02G-3 A500301 Turbine Shaft Sleeve for MX48 Power Feeder OD23mm ID17mm H29mm

Replacing a worn shaft sleeve on an MX48 power feeder should take one part, not a new gearbox. The 02G-3 A500301 turbine shaft sleeve is that part: 23 mm outer diameter, 17 mm inner diameter, 29 mm height, 19.3 g of wear-resistant metal. It sits on the turbine shaft seat and inside the feeder housing, carries the wheel axle, and takes the rubbing so the shaft and housing do not. Two reference numbers, 02G-3 and A500301, one sleeve. Ordered as a spare, it is the cheapest way to stop shaft wander, vibration and drifting feeding pressure.

A power feeder that has run for a few years usually shows the same three symptoms. The turbine shaft starts to wander, feeding pressure drifts from board to board, and the housing around the shaft seat wears oval. Most shops then buy a complete feeder assembly, or wait weeks for a part. The 02G-3 A500301 turbine shaft sleeve is the small part that prevents all three.

It is the replacement turbine shaft sleeve for the MX48 power feeder, listed under two reference numbers, 02G-3 and A500301. It measures 23 mm outside, 17 mm inside and 29 mm tall, so it seats on the turbine shaft and inside the housing without shimming. The same sleeve is catalogued as a wheel axle sleeve bearing, because it also carries the wheel axle and keeps it square to the drive. Body: wear-resistant metal, 19.3 g per piece.

Because the sleeve is the part that takes the rubbing, the shaft and the housing stay protected. Friction at the shaft seat drops, vibration at the wheel axle drops with it, and feeding pressure holds steady through a long run of stock. When the sleeve wears out, the repair stops at a 19.3 g part instead of a shaft, a housing or a gearbox. It is machined for accurate fit on the MX48, so replacement is a remove-and-refit job. Origin: China.

Everything below is dimensional, so you can check it against the part in your hand before you order.

• 23 mm outer diameter — OD 23 mm matches the MX48 feeder housing bore, so the sleeve seats without a shim or a press adapter.
• 17 mm bore — ID 17 mm is the turbine shaft seat size; the sleeve slides on and stays concentric with the shaft.
• 29 mm height — H 29 mm spans the full shaft seat, so bearing load is spread over the whole sleeve rather than one edge.
• 19.3 g single piece — One sleeve weighs 19.3 g, which keeps a spare on the shelf cheap and easy to post.
• Two reference numbers — 02G-3 and A500301 both point at this sleeve, so it can be ordered from either the parts list or the feeder manual.
• Wear-resistant metal body — The sleeve is the sacrificial part: it wears, the shaft and housing do not.
• Wheel axle sleeve bearing duty — It supports the wheel axle and holds it square to the drive, which is what stops the feeder crabbing.
• Drop-in replacement — No reaming, no bushing glue, no machining of the housing: pull the old sleeve, fit the new one.
• MX48 specific fitment — Built for the MX48 power feeder, not a generic 17 mm bushing sold as a universal part.

The choice is usually between two bad options: a complete assembly, or a week of downtime waiting for one. A sleeve shortens that decision.

• You repair, you do not rebuild. A worn 23 mm sleeve costs a fraction of a feeder assembly, and the shaft, housing and gearbox stay where they are.
• The machine is back on the line the same session. One 19.3 g part, no machining, no alignment fixture, no waiting on an outside shop.
• Feeding pressure stops drifting. A round sleeve on a 17 mm shaft seat holds the axle square, so the feeder grips the same on the first board and the hundredth.
• You stop wearing out the expensive parts. The sleeve absorbs the friction at the shaft seat, which is exactly what keeps the shaft and housing out of the repair.
• Spares inventory that fits a drawer. At 19.3 g and 29 mm tall, two or three sleeves cost almost nothing to keep on the shelf and remove the next emergency order.
• No fitment gamble. Three numbers to check — 23 mm OD, 17 mm ID, 29 mm H — and you know before you order whether it is the right sleeve.

Yes, if your feeder is the MX48. The sleeve is listed for the MX48 power feeder at 23 mm OD, 17 mm ID and 29 mm height. Check those three numbers on the worn part before ordering, because a feeder from another series will not share them.

No. They are two reference numbers for the same turbine shaft sleeve. The part is listed as 02G-3 / A500301, so whichever number appears on your parts list or in your feeder manual, it points at this one sleeve.

Measure the old sleeve on three axes: outside 23 mm, inside 17 mm, height 29 mm. A caliper on the worn part is enough. If the outside reads well under 23 mm the sleeve is simply worn, which is the normal reason to replace it.

Yes. The sleeve is catalogued both as a turbine shaft sleeve and as a wheel axle sleeve bearing, because it carries the wheel axle on the same 17 mm seat. Same part, two descriptions in the spare parts list.

Usually not. The sleeve is the wear part by design — it takes the rubbing so the turbine shaft and the feeder housing do not. Replace the sleeve first, and only look at the shaft if the wander and vibration survive a new sleeve.

Wear-resistant metal, 19.3 g per piece. The weight and the 29 mm height are the two figures to quote when you compare it with what came out of the machine.

It is a drop-in part: the old sleeve comes out of the housing, the new one goes on the turbine shaft seat and back into the housing. No reaming and no machining of the housing, which is why the repair does not need an outside machine shop.

None as listed. The sleeve is specified for the MX48 power feeder only, and the 23 / 17 / 29 mm figures are what make it model specific. For any other feeder, measure the seat and match the dimensions before ordering.
