Our expander drums work perfectly for our customers that use 3M belts to grind and smooth their material. They are designed with angled slots through the rubber rim to allow them to expand while being rotated on machines. In use, they lock the belt in place and remove scratches with their convex shape. Rubber drum expands while running to grip belts securely yet allows simple belt changes. Measure 6" diameter x 1-1/2" wide with 1/2" arbor hole.

Max. operating speed 2,400 rpm.
