These rigid pulleys come in two halves that interlock and screw together. The pulleys can be found in our TreadRunner (am-3437_TDR) robot platform and drives the powerful treads (am-3963).

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 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
