SPC V-belt pulleys

SPC V-belt pulleys are designed for the largest narrow V-belt profile - SPC and the cogged XPC, with a top width of 22 mm and a height of 18 mm. They are used in heavy drives: crushers, mills, industrial fans, large pumps and compressors.

SPC V-belt pulleys - a very high-power drive with fewer belts

One SPC belt transmits much more than an SPB belt, so a very high-power drive can have fewer grooves, be narrower and easier to maintain. Fewer belts also means fewer parts to replace during servicing. Standard-compliant grooves accept SPC or XPC belts from any manufacturer.

SPC V-belt pulleys: pilot bore and for Taper-Lock bush

Single and multi-groove SPC pulleys in subgroups by mounting method: pilot bore and for Taper-Lock bush. The largest pulleys of this profile can be found among the Taper-Lock pulleys. The diameter and number of grooves are given in the pulley name, and exact dimensions - on the product page.

SPC V-belt pulleys - customer questions

When should I choose the SPC profile instead of SPB?

When a drive with SPB belts would require a very large number of grooves or very large pulleys. Moving to SPC lets you transmit the same power with fewer belts.

Why do SPC pulleys have relatively large diameters?

An SPC belt is thick and stiff. Bending it too sharply on a small pulley would cause it to overheat and crack prematurely, which is why the smallest pulleys of this profile are larger than with SPB.
