Heavy-duty PU casters are generally used on electric forklifts, mines, stackers and AGV flat cars. Heavy-duty PU casters have relatively high requirements for wheel hubs and polyurethane applications. In the case of high load, the stability of molecular structure needs to be considered. Because of heavy-duty casters Due to the safety factor of the occasion, the safety factor of the material is very high. In the production of heavy-duty casters, the production process control, material testing, and finished product application testing are particularly critical. The service life of the casters should also be supported by test data. The particularity of caster equipment, the length of service life of the wheels is very critical to the use of equipment
