03G-1 C020349A Gearbox Assembly for MX48 Power Feeder 119x89x50.5mm Bore 37mm Includes 03G-5 Washer 163.5g

A power feeder that slips under load or drifts away from its set feed rate often points at the gearbox, not the rollers. The 03G-1 / C020349A gearbox assembly is the listed part for the MX48 feeder: 119 mm long, 89 mm wide, 50.5 mm high, 37 mm bore, 163.5 g, with 1 pc 03G-5 washer in the box. It sits between the drive and the feed rollers and takes the reduction duty. Measure those four sizes on your old housing before ordering.

A power feeder that slips under load, hums louder than it used to and drifts away from the set feed rate usually points at the gearbox, not the rollers. The housing rarely looks wrong from outside, because the play is inside, so most shops strip the feeder first and then go hunting a replacement by photo.

The 03G-1 / C020349A gearbox assembly is the listed housing for the MX48 power feeder: 119 mm long, 89 mm wide, 50.5 mm high, 163.5 g, with a 37 mm bore. It is a one-piece cast body with a machined top boss and a flat base flange, so the reduction shaft locates square to the feeder frame instead of sitting on shims.

It ships with 1 pc 03G-5 washer, the spacing part that belongs to this housing, so the axial gap at the bore is closed with the part the drawing calls for rather than a bench washer of roughly the same thickness.

The body is high-strength wear-resistant alloy / steel, cast and then machined on the bores and the mounting face, and the 37 mm bore is the reading that decides fit. Caliper that bore in two directions and check the 50.5 mm height against the old part before the feeder comes apart. Price is quoted on request.

Every line below is a property you can check on the part or with a caliper.

• One-piece cast housing — boss, rib and flange cast as one 119 × 89 × 50.5 mm body, so the two bores cannot shift against each other.
• 37 mm bore — carries the reduction shaft, and is the first reading to take off your old housing when the feeder slips.
• Machined top boss — the face around the 37 mm bore is cut flat, so the shaft runs square instead of tilting on a cast surface.
• Flat base flange — the mounting face is machined, so the bolts pull onto the casting rather than onto shims.
• 163.5 g net weight — one hand can hold it during fitting and the casting stays thick enough to carry the gear reaction load.
• 1 pc 03G-5 washer included — the spacing washer for this assembly comes in the box, so the axial gap is set with the listed part.
• Wear-resistant alloy / steel — the listed body material, chosen for the bores that carry the gear load.
• MX48 fitment — listed against the MX48 power feeder under part number 03G-1 / C020349A.
• Small shelf footprint — at 50.5 mm high and 89 mm wide, a spare stores in the space of two feed rollers.

The usual choice is between running a slipping feeder to the end of the batch and buying a whole drive section. This assembly is the third option.

• Replace the housing, keep the drive. wear collects at the 37 mm bore and the mounting face, so the gears and shafts that are still in size stay on the machine.
• Four numbers settle the fit. 119 × 89 × 50.5 mm and a 37 mm bore describe the whole envelope, so a caliper check happens before the feeder is opened.
• The washer arrives with it. 1 pc 03G-5 ships in the box, so the axial spacing part is neither a second order nor a bench substitute.
• Order by number, not by picture. 03G-1 / C020349A identifies the assembly on its own, which is what keeps a repeat order or a second spare simple.
• One casting means fewer joints. boss, rib and flange are one 163.5 g body, so there is no multi-part stack to line up on the frame.
• A spare on the shelf shortens the stop. a feeder down mid-batch stops the line; at 119 mm long the assembly stores on a shelf and covers the section that fails most often.

Yes, if the four sizes match your old part: 119 mm long, 89 mm wide, 50.5 mm high and a 37 mm bore. Those four readings cover the envelope and the shaft seat, so they confirm fit better than the model name alone.

Quote 03G-1 / C020349A. The number identifies this assembly on its own; adding the 37 mm bore and the 163.5 g weight to the enquiry lets it be matched against your feeder before it ships.

Yes. 1 pc 03G-5 washer ships with the assembly, so the axial spacing part for this housing is in the box rather than a separate line on the order.

It is the gearbox assembly as listed: a 163.5 g cast body, 119 × 89 × 50.5 mm, with a 37 mm bore and the 03G-5 washer. If your unit also needs internal gears or shafts, send the feeder model and we confirm what the number covers before you order.

Caliper the 37 mm bore in two directions at right angles and compare. A bore that reads 37 mm one way and clearly more the other has worn oval, and that reading is what tells you the housing, not the roller, is the problem.

It removes bore and mounting play, which is one cause of slip. If the rubber rollers are glazed or the chain is stretched, those parts still need attention, so check them at the same time.

High-strength wear-resistant alloy / steel, as listed for this part. The cast body is then machined on the 37 mm bore and on the mounting face, which are the two surfaces that set how the assembly sits.

Yes. Price is quoted on request and follows the quantity, so put the quantity and the 119 × 89 × 50.5 mm sizes in the same enquiry and the quote comes back against the right part.
