The precision machined swivel provides superior performance on both manually moved and mechanically powered equipment. The metal frames are zinc plated for rust resistance, and there are lubrication fittings for all moveable parts. Popular options include a face contact wheel brake to lock the wheels and a hand operated swivel lock that converts a swivel caster into a rigid caster for direct line travel. Capacity up to 7,000 pounds per caster. Model 30 features a large swivel and wheel bearing which allows for heavy loads and more arduous service. Benefits include easier swiveling, reduced swivel vibration, and longer trouble free performance. Ideal for steel mill operations, foundry equipment, and die and mold transport.

With a tire hardness of 90—“95 Durometer (Shore A), they provide excellent durability while maintaining a temperature range of -20°F to 180°F. The primary advantage of polyurethane wheels over rubber is their significantly higher load capacity – up to three times that of a comparable rubber wheel under ideal conditions on smooth floors. While polyurethane wheels roll more easily than rubber at the same load, they may become less easy-rolling when pushed to their maximum capacity.
