03A-1 C020333A Wheel Hub Assembly for MX48 Power Feeder OD65mm ID20mm H50.5mm Includes 03A-7 Bushing 154.9g

Need the part that mounts the feed wheel on an MX48 power feeder? The 03A-1 / C020333A wheel hub assembly is that part: 65 mm outside diameter, 20 mm inner bore, 50.5 mm height, 154.9 g, and each assembly includes 2 pieces of 03A-7 bushing. Both numbers, 03A-1 and C020333A, identify the same assembly, so an old parts list matches either way. It is a direct replacement for the MX48 guide sleeve seat, so the wheel goes back on the same shaft without machining or adapter rings. Price is quoted per order.

A feed wheel that works loose on an MX48 power feeder turns into three problems: the wheel wanders off the feed line, the board edge stops coming out square, and the operator keeps re-tightening a wheel that no longer sits flat. The cause is usually the hub that carries the wheel, yet the usual fixes are a complete wheel set or a trip to a service shop. This assembly replaces the failing part only.

The 03A-1 / C020333A wheel hub assembly is the mount that positions the feed wheel on the MX48 power feeder shaft. It measures 65 mm outside diameter, 20 mm inner bore and 50.5 mm height, and every assembly includes 2 pieces of 03A-7 bushing. Net weight is 154.9 g.

The 65 mm outside diameter holds the wheel face square to the stock, and the 20 mm bore seats on the shaft so the wheel returns to the position it was machined for. The 2 pcs of 03A-7 bushings take friction out of the rotating joint, so the wheel turns instead of dragging and the hub and shaft wear more slowly. That is what keeps the feed rate repeatable pass after pass.

It is made from wear-resistant metal and is supplied as a direct replacement: no machining, no adapter, no second component to order. Origin: China. Price is quoted per order.

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 assembly goes onto the wheel position without adapters, shims or reaming.
• Three dimensions you can measure. 65 mm outside diameter, 20 mm inner bore, 50.5 mm height; check the old hub against all three with a caliper.
• 22.5 mm of radial section. The 65 mm outside diameter less the 20 mm bore leaves 22.5 mm of wall, the section that keeps the wheel face square under feed pressure.
• Two bushings in every assembly. 2 pieces of 03A-7 bushing are included, so the low-friction joint is rebuilt with the hub and vibration at the wheel face drops.
• Wear-resistant metal. Machined from wear-resistant metal, so the 20 mm bore keeps its fit through continuous running.
• Holds the guide sleeve position. The assembly fills the MX48 guide sleeve seat, sitting between the wheel and the shaft rather than replacing either of them.
• Two part numbers, one part. 03A-1 and C020333A both identify this assembly, so an old parts list matches whichever number it carries.
• Single-part replacement. One assembly per wheel position; no bearing cage, seal or adapter to press in.
• 154.9 g per assembly. Light enough not to change the shaft load, and light enough to keep a spare on the shelf.

When a feed wheel starts to run loose the choice is usually to keep tightening it, send the feeder out, or buy a complete wheel set. One spare assembly removes all three.

• Fix the mount, not the wheel. A wheel that wanders is usually sitting on a worn hub, so the repair is the 154.9 g assembly rather than the wheel set around it.
• Feed rate you can repeat. With the wheel held square by a 65 mm hub on a 20 mm bore, the feed setting you dialled in still means the same thing tomorrow.
• The bushings come with it. 2 pieces of 03A-7 bushing are already in the assembly, so the job does not stall waiting on a second line item.
• Shorter downtime. One assembly, one position, no machining and no adapter, so the wheel is back on the same shaft inside the same shift.
• Cheap to keep in stock. At 65 mm across and 154.9 g, a spare takes a corner of a shelf, so the second one is already there when the first wears out.
• Identifiable from an old parts list. 03A-1 and C020333A are both on the part, so a reorder from a printed list matches without guesswork.
• Verifiable before you fit it. Three dimensions and one weight are enough to confirm the part against the old hub with a caliper and a scale.

Yes, if your feeder is the MX48 and the wheel position takes a 65 mm hub. The 03A-1 / C020333A is listed for the MX48 power feeder with a 65 mm outside diameter, 20 mm inner bore and 50.5 mm height. Measure the old hub before ordering, because a reworked shaft may no longer take the standard size.

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

Measure three things on the old hub: 65 mm outside diameter, 20 mm inner bore and 50.5 mm height. If all three match within a fraction of a millimetre it is the right part, and 154.9 g is the weight check.

Included. Every assembly is supplied with 2 pieces of 03A-7 bushing, so there is no second line item to order for the rotating joint.

No. Only the hub assembly is supplied, and only the hub assembly needs replacing. The wheel, the shaft and the gearbox side stay on the machine.

Usually a worn hub or worn bushings. The hub is what centres the wheel on the shaft, so as the 20 mm bore and the bushings wear, the wheel loses alignment and the stock starts to drift.

Wear-resistant metal. It is a machined metal assembly rather than a plastic bushing, which is why the 20 mm bore holds its fit under continuous feed load.

154.9 g per assembly. Price is quoted per order: send the part number 03A-1 / C020333A and the quantity you need, and a quote comes back.
