## Description

With a doubled width that multiplies motion possibilities, this 16 tooth, 8mm REX™ bore pinion pulley can drive up to two 5mm pitch HTD belts of widths of 9mm or less. It’s a fantastic solution in a skid-steer drivetrain where two centrally-located motors power the chassis via belts extending to the front and back wheels on each side.

The pair of set-screws prevent the pulley from moving axially on the 8mm REX™ shaft. Built-in shims on each side allow the pulley to rest against a bearing while providing clearance between the pulley and the bearing’s outer race.
