DESCRIPTION
Martin idler bushings are designed to accommodate stock V-belt drives, sprockets, timing belt pulleys, or other products that use QD or MST® type bushings. They are equipped with two electric motor grade, permanently lubricated ball bearings, mounted on a precision shoulder bolt. Shoulder bolt and two hex jam nuts are zinc plated. Installation is made by slipping the threaded shaft through a hole bored in support structure and tightening the locking nut. Sheaves, sprockets or other products can be removed without dismounting the idler bushing.
