The special Semi-Hub roller, patented by Maggi, allows for the replacement of the worn rubber without having to change the entire wheel—only the outer coating needs to be replaced. This ensures significant cost savings and reduces waste, resulting in a lower environmental impact. Additionally, this innovative system helps to reduce roller wear by over 50% compared to standard rollers.

For a visual explanation, please refer to the attached image.

The "rubber coating for Semi-Hub System 120 x 60 mm" accessory (code 31301019) does NOT include the two aluminum semi-supports that are needed to complete the wheel and must be ordered separately (code 41300062).

For the old variant "rubber coating for Semi-Hub System 110 x 50 mm" (code 31500062), the aluminum semi-hub is NO longer available as it has been out of production for several years.

The two Semi-hub supports can be replaced either as a pair or individually, depending on your needs and the level of wear.

Single Semi-hub accessory - 120x60 mm - code (41300062)

The semi-hub supports measuring 100x50 mm are no longer available. Currently, the Steff 2033 and STEFF 20316 POWER feeders are equipped with semi-hubs measuring 120x60 mm. However, the rubber coatings for semi-hubs measuring 100x50 mm are still provided under code: 31500062.

The standard gears provided for speed doubling are as follows:

STEFF 2038 and 2048 SMART = Gears Z43, Z22

STEFF 2032 = Gears Z46, Z24

STEFF 20316 POWER = Gears Z30, Z35"

The STEFF 2033 and STEFF 20316 POWER models are fitted with SEMI-HUB rollers ONLY and cannot be replaced with standard rollers. See the attached image to appreciate the differences between standard rollers and SEMI-HUB rollers.

The maximum height at which I can position the wheels of the power-feeder relative to the work surface may vary depending on the model (please refer to the image for the specific data related to your model of interest). On the other hand, the minimum height is always zero, as the wheels will always make contact with the work surface

First of all, it is necessary to set the most appropriate feeding speed according to the type of processing to be carried out.

The right working speed is determined by considering various aspects: the type of material to be feeded (weight and surface finish) and the extent of the processing or removal to be performed.

As a good rule of thumb, the more important the processing and the heavier the piece to be feeded, the lower/slower the selected speed should be.

In addition to the feeding speed, the choice of the type and number of rollers is also important:

Soft rubber rollers with high grip are for very smooth and lacquered surfaces

Hard rubber rollers with high resistance are for rough surfaces

Steel wheels are for rough surfaces

Rubber tracks are for short and narrow pieces

To feed long pieces, we recommend purchasing the STEFF 2068 power-feeding unit with 6 rollers.

Discover more about speed and the types of rollers available by viewing the attached images!

Please, make reference to the enclosed pictures and instructions with respect to each model ... 

Please, watch the enclosed video ...

Please refer to the attached speed table.

Please refer to the attached table for the available stand types ...

In the attachment, you will find the complete comparison table of all models in the Maggi power-feeders line.

Maggi power-feeders are available in the following voltages: 

On all power-feeding units (excluding STEFF 2032, STEFF 2033, and STEFF 20316 POWER), it is possible to install softer springs (Accessory on request - code 41200013) to achieve greater cushioning (suspension) of the wheels (> 20 mm). One spring is required for each wheel.

The rollers we mount on our power-feeders differ from each other in TERMS OF TYPE, MATERIAL, and DIMENSIONS.

TYPE

STANDARD: with aluminum support and FIXED rubber coating

SHS: with "Semi-Hub" aluminum support and REPLACEABLE rubber coating

MATERIAL

Rubber: patented vulcanized "Feeder Grip" with high grip and durability, available in different SHORE indices (which determine the hardness and flexibility of the rubber for various uses)

ROLLERS 40 Shore: softer rubber, offers greater grip suitable for dragging coated materials, very smooth surfaces, and delicate finishes.

ROLLERS 50, 65, and 70 Shore: harder rubber, suitable for dragging standard panels, semi-finished products, with rough surfaces.

CAST IRON ROLLERS: for dragging raw wood.

DIMENSIONS:

The rollers that are standardly mounted on professional power-feeders are STANDARD rubber rollers, 120 x 60 mm with 50 Shore hardness.

The STEFF 2033 and STEFF 20316 POWER feeding units are equipped with SHS rubber rollers, 120 x 60 mm - 50 Shore.

The STEFF 2032 is equipped with standard rubber rollers, 80 x 28 mm - 50 Shore

As of today, our range does NOT include a stand with motorized positioning, but only manual.

Yes, it is possible to apply a new power-feeding unit to an old stand, as long as it is manufactured by Maggi; however, it is always advisable to verify compatibility by measuring the following dimensions, as per the attached drawing:

- Diameter of the hole in the horizontal tube, and diameter of the base hole: 58 mm

- Inner diameter of the collar hole: 75 mm

- Height (thickness) of the collar: 30 mm

Attention! STEFF 2032 and STEFF 2033 models are always supplied complete with a stand; it is not possible to purchase only the feeding unit without its stand.

Please, make reference to the enclosed pictures and video

Yes, it is completely normal for the motor of a feeder to reach high temperatures (even up to 50°C) during operation without causing any damage or affecting the proper functioning of the device. This is a typical characteristic of the equipment when in use.

The Maggi rubber-coated rollers are made from vulcanized rubber, which is treated at high temperatures. This process protects the product from wear in temperatures ranging from -20 °C to +40 °C, making them resistant to weather conditions and ensuring a long lifespan.

The lifespan can vary depending on the type of processing and the material being conveyed.

The Maggi feeders are supplied complete with an electric cable (3 meters long for professional and semi-professional feeders and 1 meter for the STEFF 2032), but they do NOT come with a power plug. The compatible plug variants for different machine tools are numerous and have very different characteristics depending on the country, making it impossible to standardize their supply.

All Maggi feeders - except for the STEFF 20316 POWER - are also available in the single-phase version.

PROFESSIONAL FEEDERS

LUBRICATION TYPE A: SLIDING POINTS ON THE STAND: Thread of the crosspiece, lifting screw, and rack of the horizontal tube. Lubricate with grease type "Persian Poligrease EP/2" or equivalent. Frequency: As needed, if the parts show excessive friction.

LUBRICATION TYPE B: WHEELS through grease fittings/nozzles located on the shafts of the rollers and under the feeder. Lubricate with the appropriate lubrication pump (provided with the feeder), pumping the grease into the nozzles. Use grease type "Persian Poligrease EP/2" or equivalent. Recommended frequency: Every 3 months.

LUBRICATION TYPE C: OIL PAN AND TRANSMISSION Regularly check the oil inside the pan. The oil level should not drop below 4 cm. Use oil type "IP MELLA -NA 220" or equivalent. Recommended frequency: Every 6 months.

SEMI-PROFESSIONAL (STEFF 2033) AND HOBBY (STEFF 2032) FEEDERS

The STEFF 2033 model has wheels mounted on a bearing system, for which NO lubrication is necessary; therefore, the lubrications to be performed are exclusively types A and C.

The STEFF 2032 HOBBY model does not require lubrication on the wheels. The lubrications to be performed in this case are also exclusively types A and C.

Please refer to the attached image to identify the standard color of the rubber, for the various types of available rollers ..

In the attached image, you will find the rollers that we supply as standard, for the different types of automatic power-feeding units.

TYPE A ADJUSTMENT: Positioning the feeder at 'Point 0'

The zero point represents the height at which the power-feeding unit must be positioned to correctly pull the piece. Since the feeder must exert a certain pressure on the piece, it is advisable to position it at a height such that the rollers remain 3/4 mm lower than the work surface. This distance represents the 'preload' that is intended to be exerted on the piece. The mentioned distance varies based on the pressure you want to exert and the type of processing.

TYPE B ADJUSTMENT: Unlocking the counter.

Using a 2.5 mm Allen key, act on the collar of the counter located under the handle and look for the release screw that is under the rubber sheath. Once the screw is found, unlock the counter from the lifting mechanism.

TYPE C ADJUSTMENT: Resetting the counter.

Once the counter is unlocked, by turning the screw around the axis of the handle, reach the position 0000-0. The last zero to the right of the line represents tenths of a millimeter.

TYPE D ADJUSTMENT: Locking the counter.

Once you reach zero, tighten the internal screw again to lock the movement of the counter to that of the lifting handle. By acting on the counter from this position (0), it is possible to adjust it to all the thicknesses of the panels that you intend to work on."

In the attached image, you will find the dimensions and measurements of the accessory 'Tipper clamp 96' (code 22100151)."

The feeders are supplied with a 3-meter long electric cable; the only exception is the hobby feeder, STEFF 2032, which has a shorter cable, measuring 1 meter."

Attached is the complete list of recommended spare parts for the automatic feeders...

For pricing information, please contact our spare parts office (service@maggi-technology.com )."

Please see the attached video..."

Please see the attached drawings..."

The vertical and horizontal tubes of the stands for the professional feeders (STEFF 2034 / 38 SMART / 2038 / 2038-CI / 2044 / 2048 / 48 SMART / 2068 / VARIO 3 / VARIO 4 / SUPERSONIC 3 / SUPERSONIC 4) have a diameter of 58 mm; while the tubes of the stands for the STEFF 2033 feeder have a diameter of 49 mm, and those for the STEFF 2032 feeder have a diameter of 40 mm.

It is a safety system that, thanks to the careful design of the cross support, prevents any risk of disconnection between the various components, even in the event of improper tightening by the operator, thus avoiding the risk of the power-feedig unit detaching and falling, which could cause injuries to the operators.

In the case where the support is mounted on a potential "Tilter" (see Fig. 2), the Elastic Pin System, through the pin (13b) (see Fig. 1), ensures that the vertical tube (11) does not slide out of the base (12), even if the handle has not been locked. This safety system also applies to the horizontal tube (10) (see Fig. 1), as the pin (13a) prevents the pipe (31) from sliding out of the tube itself."

The distance between the mounting holes for professional feeders, specifically for rollers measuring 120 x 60 mm and 118 x 50 mm, is 48 mm, while for the 80 x 28 mm rollers, it is 32 mm. The SEMI-HUB rollers used on the STEFF 2033 and STEFF 20316 POWER models do not have mounting holes.

Please see the attached image for further clarity."

Yes, the stands of the professional feeders are supplied with a pipe-joint-collar group (also called joint group or connection group) to allow connection to the feeding device.

Some models of power-feeders such as: STEFF 20316 POWER, STEFF 2033, and STEFF 2032, due to their particular design, do not require the collar; the stand is supplied only with a pipe that connects to the joint already mounted on the body (baty) of the feeder.

See images for further clarity..."

The STEFF 2033, thanks to its compact dimensions but professional performance, is undoubtedly the ideal model for working on a combination machine."

For the internal lubrication of the gears of our feeders (automatic advancements), we recommend using IP - MELLANA OIL / ISO VG 220.

TECHNICAL DATA:

Density at 15°C = 0.895

Viscosity at 100°C = 18.7

Viscosity at 40°C = 220

Viscosity index = 95

Flash point V.A. = 240

Pour point = -21

The complete technical data sheet and safety data sheet are available upon request (service@maggi-technology.com )."

The stand, or support, for the feeder consists of:

- A cast iron base, with mounting holes, for fixing to the machine tool table, or tilting device

-A vertical tube

- A crosshead assembly

- A horizontal tube with rack

- Positioning handwheels

- A top lifting handle

- A pipe assembly, joint, and collar for attaching the feeder 

(the stand for STEFF 20316 POWER, STEFF 2033, STEFF 2032 only includes the pipe assembly, while the joint assembly is provided pre-mounted on the baty - structure of the automatic power-feeder ; the collar is not needed.)

The STEFF 2033 and STEFF 2032 power-feeding units include the stand in the standard equipment, while all other models are sold WITHOUT a stand, which can be purchased separately as an accessory."

STEFF 2033 and STEFF 2032 power feeding units include the stand in the standard equipment, while all other models are sold WITHOUT a stand, which can be purchased separately as an accessory."

Please, refer to the attached table ...

The height of the feed roller, relative to the work surface, is adjusted by manually turning the handwheel positioned at the top of the vertical column of the stand; the STAND PLUS (cod. 13400600) also has a numeric counter on which the exact height can be read for more accurate and faster adjustment.

Attached you will find all the layouts with the overall dimensions for each type of Maggi feeder.

Yes, in the range of Maggi feed units, the STEFF SUPERSONIC 3 and 4 models have variable speed with an electronic inverter.

In the range of Maggi feeders, there is already a specific model with tracks, namely the STEFF 2038-CI (see product data sheet in the products section of the website). The replacement of the rollers with tracks, through the special PULLEY AND TRACK KIT (Spare part to be ordered separately) is possible ONLY on the 3-ROLLER PROFESSIONAL models, such as: STEFF 2034, STEFF 2038, STEFF 38 SMART, but this operation must be carried out by a specialized technician. For more information, we invite you to contact our service department (service@maggi-technology.com).

Automatic feeders are an indispensable safety device:

- They ensure the operator's safety.

- They guarantee precise operations with consistent quality on every piece.

- They provide higher productivity compared to manual pushing by an operator.
