63x48mm SCM Spare Parts Nylon Swing Arm Roller for Sliding Table Saw Machine

Looking for the white nylon roller that carries the carriage on an SCM sliding table saw? This is it. Nominal ordering size 63*48 mm; the flange measures 61 mm across, the roller is 48 mm high, and the bore through the hub is 12 mm. Those three numbers settle fitment without a parts book: if the old roller reads 61, 48 and 12, this one goes straight back on the arm. Moulded white nylon, 1 part number, other sizes also available.

A sliding table that no longer glides cleanly usually has one worn part, not a worn saw: the nylon roller that runs in the swing arm. Three things make that repair annoying. The roller costs a fraction of a service call, the parts search takes longer than the swap, and a roller picked by eye puts the carriage back at a different height on every corner.

This is that roller. The ordering size is 63*48 mm; the flange measures 61 mm across, the overall height is 48 mm, and the bore through the hub is 12 mm. Those three numbers decide fitment, not the machine's age or the number printed on the old wheel.

The body is moulded in white nylon as a flanged spool: a flange at each end, a 12 mm bore through the hub, 61 mm across the outside. Nylon is the wear surface in this position, taking the abrasion and the impact of a loaded carriage through thousands of cuts without a metal face bearing on the track.

Other sizes are also available for other carriage designs. Because the fitment test is three measurements, a roller that reads 61 mm, 48 mm and 12 mm is the match.

Fitment comes down to three measurements and one material:

• Ordering size 63*48 mm. The quote, the invoice and this page use the same two numbers, so a repeat order needs no photo.
• 61 mm across the flange. Measured over the flange: the diameter that has to clear the track and seat in the arm.
• 48 mm overall height. Flange face to flange face — the figure that sets how high the carriage rides.
• 12 mm bore. A plain through-bore in the hub, so the roller mounts on the shaft the worn one came off.
• White nylon body. Moulded in one piece from flange to flange, with no bonded tyre to peel at 61 mm.
• Flanged spool shape. A flange at each end of the barrel, so the roller is held sideways by its own shape.
• Nylon at the wear point. The 61 mm barrel gives up the material, leaving the arm and track at the size they were machined to.
• Impact absorption. Nylon deflects under a panel landing on the carriage, so the 48 mm body absorbs the hit instead of the arm.
• SCM sliding table saw fitment. Catalogued as spares for SCM sliding table saws, in the original 63*48 mm footprint.
• Other sizes available. Supplied in other diameters and heights, so a mixed carriage is covered by 1 supplier.

The choice is usually between a factory parts order and a roller that is close enough. This one is a measurement: 61 mm, 48 mm, 12 mm.

• Fitment settled before the order. If the worn roller measures 61 mm across, 48 mm high and 12 mm through the bore, the carriage goes back to the height the saw was set up at.
• The arm stays on the machine. Only the 1 nylon roller is replaced, so the swing arm, its shaft and the track are not disturbed and the saw keeps its alignment.
• Nylon gives up the material, not the track. The 61 mm barrel is the sacrificial surface, so the rail the carriage runs on keeps its profile through repeated changes.
• A repair priced like a spare part. One moulded nylon roller and 3 measurements, against a service call and the days a table saw sits idle waiting for one.
• One supplier for a mixed carriage. Other sizes are available from the same source, so front and rear stations with different 63*48 mm footprints do not become two purchase orders.
• Spares that match the machine's own geometry. Supplied as SCM sliding table saw spares in the original 48 mm height, so the carriage sits where the manufacturer put it.

Yes, if the old roller measures 61 mm across the flange, 48 mm high and 12 mm through the bore. Those three numbers are the whole fitment test; the machine model and the number on the old wheel do not change the answer.

No. 63*48 mm is the ordering size that identifies the part. The flange itself measures 61 mm across and the roller is 48 mm high, and those are the numbers to check against the old one.

12 mm. A plain 12 mm through-bore in the hub, so the roller mounts on the shaft the worn one came off without a bushing.

White nylon. The whole body is moulded in nylon from flange to flange, with no rubber tyre bonded onto a core.

Yes. It is catalogued under 63*48 as a spare part, so a single worn roller can be replaced without re-specifying the arm or the carriage.

Yes. Other sizes are also available for other carriage designs, so measure the old roller before ordering rather than assuming 61 × 48 mm fits every saw.

Made in China. Origin is stated on the packing and the invoice to match the documents your forwarder needs.

Take three readings: 61 mm across the flange, 48 mm from flange face to flange face, and 12 mm through the bore. If all three match, order the 63*48.
