Material Performance Parameters

Polyurethane is renowned for its high strength, wear resistance, and impact resistance. In logistics warehouses, this type of  caster is typically used to support and move heavy-duty shelves and other equipment. Its excellent wear resistance allows it  to withstand frequent use, reducing maintenance costs and downtime. Additionally, polyurethane heavy-duty casters offer a  quieter operation, helping to maintain a peaceful working environment and improving the comfort of employees.
