Polar EMC Split Pulley Assembly – SP290

V Belt Split Pulley Assembly for Polar EMC Paper Cutters. (231482, 231481, and 017289) 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 EMC hydraulic pump. Its outside diameter measures 7-3/8″ (187mm).

This pully has been Hardcoat Anodized to give maximum hardness and wear resistance to the belt contact surfaces.

This complete assembly fits the Polar 92 EMC, Polar 115 EMC, Polar 137 EMC, and the Polar 155 EMC models. Included is both pulley halves, three steel adjusting shims (our part number SP202) equivalent to Polar part numbers 230068 & 240788, and the three bolts to hold the two halves together. Each shim is .5mm (.020″) thick. The hub half of the pulleys have threaded steel inserts installed where the two pulley halves bolt together, similar to the originals, to prevent the threads from stripping.

Equivalent to Polar part numbers 231482, 017289, and 240788.
