20 Tooth Track Drive Pulley

These molded plastic pulley halves are specially designed to drive our Rhino Track Drive belt (am-3288) and are used as drive pulleys in the Rhino Track Drive module (am-3322). This design features strength improvements over earlier designs.

These two pulley halves are made from the Rev4 pulley design, which includes these improvements over the Rev3 design:

less recessed depth for screw counter bore
6 additional ribs supporting the material around the bearing pocket
increased radius for ribs supporting the material around the bearing pocket
added a fillet feature at the base of the screw counter bore

The process for improvements for this Rev4 version is documented on this web page.
