3" X 1-1/4" Polyurethane Wheel Casters

Choose the appropriate hardness of 3" x 1-1/4" Polyurethane Wheel Casters
The appropriate hardness of 3" x 1-1/4" Polyurethane Wheel Casters depends on the specific application scenario and requirements. Here are some selection suggestions:
Places with high ground protection requirements
If the floor material in the workplace is relatively soft or needs to be protected, it is recommended to choose polyurethane coated wheels with a hardness range of 30A-70A. These wheels have good elasticity and shock absorption performance, which can reduce ground impact and scratches.
2. In situations with moderate loads and transportation requirements
For moderate loads and transportation requirements, it is recommended to choose 3" x 1-1/4" Polyurethane Wheel Casters with a hardness range of 75A-85A. These wheels can provide good load-bearing capacity and wear resistance, as well as good rolling resistance and skid resistance.
3. High intensity and heavy load scenarios
For high-strength, high-speed, and heavy-duty scenarios, it is recommended to choose polyurethane coated wheels with a hardness range of 90A-95A. These wheels have very high hardness, wear resistance, and compression resistance, which can provide stable and long-lasting performance in harsh environments.
