02G-2 A500302 Wheel Axle Bearing Sleeve for MX48 Power Feeding Machine OD23mm ID17mm H15mm

Need the sleeve that keeps an MX48 power feeder wheel running true? The 02G-2 / A500302 wheel axle bearing sleeve is the cylindrical replacement part for that position: 23 mm outside diameter, 17 mm bore, 15 mm height, 18.6 g. It seats in the wheel hub and carries the axle so the wheel stays square and stock feeds in a straight line instead of walking off the fence. Both numbers, 02G-2 and A500302, identify the same part, so either number on your parts list matches. Price on request.

A feeder wheel that wobbles shows up as three problems: stock that walks away from the fence, a feed rate you can no longer repeat, and a wheel hub that wears deeper every month. Most of the time the cause is one small part, the sleeve between the axle and the hub. Ordering a complete wheel assembly to cure it costs far more than the sleeve itself.

The 02G-2 / A500302 wheel axle bearing sleeve is the cylindrical sleeve that sits in that position on an MX48 power feeder. It measures 23 mm outside diameter, 17 mm inside diameter and 15 mm height. The 6 mm difference between bore and outside diameter leaves a 3 mm radial wall, which is the section that holds the axle steady under feed pressure. Net weight is 18.6 g.

Fitted correctly, the sleeve supports the wheel axle, reduces friction at the rotating joint and keeps the wheel rotating smoothly. Because the bore and the outside diameter are made to those three figures, the wheel returns to its original position on the shaft instead of being shimmed back into line, and the hub face is not ground down to compensate.

It is made from wear-resistant metal, is marked with both part numbers, and is supplied as a single direct replacement: no machining, no adapter, no second part to order. Origin: China.

What is on the part and what it does, in the order a buyer checks it:

• Exact MX48 application. Listed for the MX48 power feeder, so the sleeve goes into the wheel hub position without adapters, shims or reaming.
• Three dimensions you can measure. 23 mm outside diameter, 17 mm bore, 15 mm height; check your old sleeve against all three with a caliper before ordering.
• 3 mm radial wall. The 6 mm step from bore to outside face gives a 3 mm wall, the section that keeps the axle square while the wheel is loaded.
• Cylindrical wheel hub type. A plain cylindrical sleeve, matching the wheel hub bearing sleeve position on this feeder rather than a flanged or split bush.
• Low-friction rotation. The sleeve carries the axle and reduces friction at the rotating joint, so the wheel turns instead of dragging on the hub.
• Wear-resistant metal. Made from wear-resistant metal so the 17 mm bore holds its size through continuous running.
• 18.6 g per part. Light enough not to load the axle, and light enough to keep as a stocked spare.
• Two part numbers, one part. 02G-2 and A500302 both identify this sleeve, so an old parts list matches whichever number it carries.
• Single-part replacement. One sleeve per position; no bearing cage, seal or adapter is involved.

When a wheel starts to wobble the choice is usually to keep running it, send the feeder out, or buy a whole wheel assembly. One spare sleeve removes all three.

• Fix the cause, not the symptom. A wheel that wanders is usually a worn sleeve, not a worn wheel, so the repair is the 18.6 g part rather than the assembly around it.
• Repeatable feed rate. With the axle held square in a 17 mm bore, the wheel tracks the same line pass after pass, so the feed setting you dialled in still means the same thing tomorrow.
• Less wear on the parts around it. Less friction and vibration at the joint means less load on the wheel, shaft and hub face.
• Shorter downtime. One sleeve, one position, no machining and no adapter, so the wheel goes back on the same shaft in the same shift.
• Cheap to keep in stock. At 23 × 17 × 15 mm and 18.6 g, a spare takes almost no shelf space, so the second one is already there when the first wears out.
• Identifiable from an old parts list. 02G-2 and A500302 are both on the part, so a reorder from a printed list matches.
• Verifiable before you fit it. Three dimensions and one weight are enough to confirm the part against your old sleeve with a caliper and a scale.

Yes, if your feeder is the MX48 and the wheel hub takes a cylindrical sleeve. The 02G-2 / A500302 is listed for the MX48 power feeder with a 23 mm outside diameter, 17 mm bore and 15 mm height. Measure your old sleeve before ordering, because a hub that has been reworked may no longer take the standard size.

Yes. Both numbers identify the same wheel axle bearing sleeve. Use whichever number your parts list or manual shows; they lead to this one part.

Measure three things on the old sleeve: 23 mm outside diameter, 17 mm bore and 15 mm height. If all three match within a fraction of a millimetre, it is the right part. Weight is 18.6 g as a second check.

Wear-resistant metal. It is a machined metal sleeve, not a plastic bushing, which is why the bore holds size under continuous feed load.

No. Only the sleeve is supplied and only the sleeve needs replacing. The wheel, the axle and the hub stay on the machine.

Usually a worn sleeve. The sleeve is the part that centres the axle in the hub, so as its 17 mm bore wears, the wheel loses alignment and the stock starts to drift. Fit a new sleeve and alignment comes back.

Yes. It is one cylindrical sleeve in one position, with no adapter, no machining and no bearing cage to press, so the wheel goes back on the same shaft.

18.6 g per part. Price is quoted per order: send the part number 02G-2 / A500302 and the quantity you need, and you get a quote back.
