02G-4 A500347 Casing Guide Sleeve for MX48 Power Feeder OD37mm ID31.7mm Bottom OD43mm H15mm

Replacing a worn casing guide sleeve on an MX48 power feeder starts with the right ring. 02G-4 A500347 is that ring: OD 37 mm, ID 31.7 mm, 43 mm across the bottom face, 15 mm high, 36 g. The 31.7 mm bore holds the internal shaft and sliding guide in line inside the casing, and the 43 mm bottom face stops on the casting, so the sleeve seats square and cannot sink through the bore. Check those four dimensions against the part in your hand — if they match, it drops in.

A power feeder rarely fails at the motor. It fails at the casing: the shaft starts walking in the housing, the feed drifts a fraction of a millimetre on every pass, and the bore in the casting wears into a shape no new sleeve will sit in properly. All three end the same way — the same run re-set, a different board off it.

The 02G-4 A500347 casing guide sleeve is the replacement part for the MX48 power feeder. It is a machined ring — 37 mm outer diameter, 31.7 mm bore, 43 mm bottom face, 15 mm high — that sits in the casing and guides the internal shaft and sliding components while they turn and move.

Two of those numbers do the work. The 43 mm bottom face is wider than the 37 mm body, so the sleeve lands on the casting shoulder and stops there instead of dropping through; that shoulder, not the fitter, sets the depth. The 31.7 mm bore is the running surface — it holds the guide and shaft at a fixed position, so clearance at the housing does not turn into wobble at the feed rollers.

Net weight is 36 g, material is wear-resistant metal, and both markings — 02G-4 and A500347 — are the same sleeve. Two spares cost less in freight than one stripped feeder costs in downtime.

What makes this a replacement rather than a part that needs fitting:

• Four dimensions, all checkable — OD 37 mm, ID 31.7 mm, bottom OD 43 mm, height 15 mm; measure the old sleeve against all four before ordering.
• Stepped locating shoulder — the 43 mm bottom face is 6 mm wider than the 37 mm body, so depth is set by the casting, not by the fitter.
• One application, no trimming — built for the MX48 power feeder only; it is not a universal bush cut down to size.
• Machined ring, not pressed sheet — a solid wear-resistant metal body of 36 g, with the bore carrying the guide and shaft through the full 15 mm height.
• Wear lands on the sleeve — the 31.7 mm bore takes the sliding contact, so the 43 mm seat machined into the casing stays uncut.
• Nothing to adjust after fitting — the ring locates on its own shoulder, with no shim, thread or fastener to set at 15 mm depth.
• Easy to install and replace — one sleeve out, one sleeve in, with the casing left on the machine.
• Identified two ways — 02G-4 and A500347 mark the same sleeve, so either number on your parts list matches what arrives.
• Small enough to keep in stock — 36 g each, so a pair sits in the spares drawer without a purchase decision.

When the casing sleeve wears you have two options: keep feeding and accept the drift, or take the feeder out of service. This ring is the third.

• A 36 g part instead of a service call. The sleeve is the smallest item in the assembly and the one that wears first, so the repair stays a parts order rather than a workshop job.
• The shoulder sets the depth. 43 mm against 37 mm means the sleeve can only come to rest square on the casting — no measuring and no guesswork at refit.
• The casting stays untouched. Contact wear goes into the 31.7 mm bore and the 36 g ring, so the housing seat behind it keeps its original shape order after order.
• Feed repeatability comes back. With the shaft held in a fixed 31.7 mm bore, a run set once returns the same result on the next board instead of drifting by a fraction of a millimetre.
• Verifiable before you fit it. All four dimensions are measurable with a caliper on the bench, so a wrong part is caught before the feeder is stripped down.
• Stock two, not one. At 36 g the second sleeve adds almost nothing to freight, and it removes the wait between a worn ring and a running feeder.

The MX48 power feeder. 02G-4 A500347 is listed for the MX48, and its 37 mm outer diameter, 31.7 mm bore, 43 mm bottom face and 15 mm height are the four numbers to check against the machine on your floor.

OD 37 mm, ID 31.7 mm, bottom OD 43 mm, height 15 mm, net weight 36 g. The bottom face is the widest point at 43 mm, and the body steps down to 37 mm above it.

Either. Both markings identify the same casing guide sleeve, so quoting 02G-4 / A500347 together removes any doubt at the order desk.

Measure the old part on four points: 37 mm across the body, 31.7 mm across the bore, 43 mm across the bottom face, and 15 mm from the bottom face to the top edge. If all four match, it is the same sleeve.

It is the locating shoulder. It gives the sleeve a seat 6 mm wider than its own 37 mm body, so the ring stops on the casting instead of dropping through the bore and comes to rest square.

Wear-resistant metal, 36 g net. One sleeve travels in a padded envelope, so a spare adds almost nothing to a parts shipment already going out.

Inside the feeder casing, guiding the internal shaft and sliding components. The 31.7 mm bore holds the shaft aligned over the 15 mm ring height, and the 37 mm outer face is what the casing carries.

Yes. The same list carries the 03G-5 gear washer (42 mm OD / 38 mm ID / 6 mm H), the 03G-4 gearbox cover (119 x 89 x 31 mm), the 04A-26 26-link chain, rubber feed rollers and the 24T / 30T copper gear wheels.
