Profile: Sunray, Inc. specializes in providing polyurethane and urethane products. Our products include polyurethane wheels, covered bearings, extended hub wheels, drive rollers, V-groove wheels and flanged wheels. Our heavy duty polyurethane caster wheels are being used on towing carts at higher than normal speeds, and our industrial urethane wheels are being used on stacker systems. We can recover, retread, or design any heavy duty polyurethane wheels. Our extended hub wheels are available with bearings, or with a straight bore. We also offer retreading and CNC milling services. Our zero crush wheel is provided with a chambered construction. These wheels can delicately handle materials that are easily damaged by conventional wheels and rollers.
