Polar Split Pulley Assembly – Long Hub – SP188

V Belt Split Pulley Assembly for Polar CE Paper Cutters. (equivalent to Polar 010280 and 010127) This precision machined aluminum split pulley is a direct replacement for the original die cast pulley used on the tapered output shaft on the Polar Model CE hydraulic pump. This pulley has been Hardcoat Anodized to give maximum hardness and wear resistance to the belt contact surfaces.

Included is both pulley halves, four steel adjusting shims (our part number SP182), and the three bolts to hold the two halves together. Each shim is .5mm (.020″) thick. The pulleys have threaded steel inserts installed where the two pulley halves bolt together, similar to the originals, to prevent the screw threads from stripping out in the aluminum.

This is the “Long Hub” version of this pulley assembly. The hub length measures approximately 7/8″. (See our part number SP187 for the 1/2″ long “Short Hub” version.)

See the attached photo to determine if you have the “Long Hub” or the “Short Hub” version of this sheave.
