SPA Taper Bore Pulleys

As standard, V-belt pulleys are available in undrilled, pre-drilled or clamping bush variants. The clamping bush variant, also known as a taper or taperlock variant, is always used in combination with the associated clamping bush. The undrilled and pre-drilled variants must first be provided with a bore hole and possibly with a key way and a threaded hole.

The clamping bush variant is equipped as standard with a conical bore and threaded holes for fastening the bush to the shaft. The associated clamping bushes are available with bore holes in various sizes and with a key way in both metric and imperial dimensions. They are supplied together with the appropriate socket head screws and can be found in this online shop under clamping bushes. The major advantages with using a clamping bush lie in the fact that the pulley and shaft do not have to be modified beforehand and that mounting and removal are very easy.

The most common types of V-belt pulleys are SPZ, SPA, SPB and SPC. They are stocked in both standard and clamping bush variants. Of course the corresponding pulleys are also available for the remaining V-belt types. Furthermore, we supply V-belt pulleys to match customer specifications, and in our turning shop we can machine standard pulleys according to customer requests or drawings.
