The groove sleeve, which is a flat loop, slips into the drive belt groove on conveyor rollers. The thermoplastic polyurethane provides a high coefficient of friction with the steel roller and drive belt, reducing slippage of the belt under heavy loads, and increasing conveyor weight capacity by up to 50 percent.
The company currently uses a flat sheet of SS-1485 material, 0.03 inch thick and cut into strips 1/4-inch wide. The strips are then welded into the closed loop groove sleeve.
