Medium-Duty Single ball bearing PU Caster
Our medium-duty single ball bearing PU caster is a cost-effective mobility solution widely used for industrial trolleys, workshop tool carts, medical equipment, hotel service carts, storage racks and light mobile machinery. Designed with a single axle structure, this caster delivers smooth rolling performance, reliable medium load capacity and excellent floor protection, suitable for long-term indoor handling operations.
The wheel is made of premium polyurethane material. It combines good hardness and toughness, featuring outstanding abrasion resistance, tear resistance and load-bearing performance. The wheel runs quietly during movement and leaves no black marks on wooden floors, tiles, epoxy floors and vinyl floors, effectively protecting ground surfaces.
Adopts optimized single axle assembly. Simple and compact structure, easy for maintenance. The axle firmly locks the wheel, reducing wheel wobble during transportation and ensuring stable linear rolling.
Thick stamped steel bracket with galvanized anti-rust treatment. The precision ball swivel enables flexible 360-degree rotation with low pushing force. Flat four-hole mounting plate provides stable installation. Multiple types are available: swivel caster, swivel caster with brake and fixed rigid caster.
Optimized for medium-weight mobile equipment. Uniform stress distribution prevents deformation under regular load, bringing stable and labor-saving handling experience.
Industrial handling trolleys, medical mobile equipment, hotel service carts, office mobile cabinets, workshop tool carts, warehouse storage racks, cleaning equipment and exhibition display stands.
