Shepherd Casters manufactures plate casters for medium-duty mobility applications in store fixtures and material handling equipment. These casters feature a heat-treated steel construction with RoHS-compliant zinc plating for extended durability, and polyurethane / thermoplastic rubber wheels with a dual ball bearing raceway to ensure even load distribution. Selected models also feature an NSF-approved thread guard to help prevent entangling of debris into the wheels. These Shepherd caster wheels are capable of bearing loads up to 315 lb (142.88 kg) and temperatures up to 180 degrees Fahrenheit. These casters are available in A-, C- and D-plate mounting options on Raptor Supplies.
