A useful range of small but heavy duty nylon rollers.For convenience each size has the same hub width and diameter bore. The rollers are fitted with two ball races with side shields making them very free running and quiet.

The special feature is that they can be ordered with either a plain face, a vee groove, or a round groove. Ideal for constructing heavy duty travellers, small lifts, under stage tracking, etc. The vee grooved rollers will run smoothly on inverted angle iron tracks. Trucks will self centre if there is any width discrepancy between the tracks whereas flanged wheels running on square tracks may bind and screech.

Bore: 10 mm
Hub width: 25 mm.
