Frequently Asked Questions
Q: What are the specifications for the 312021-003-A load wheel assembly?
A: The 312021-003-A is a precision-machined load wheel assembly with 95A Shore hardness polyurethane tread. It features an integrated shoulder bearing configuration for enhanced performance and stability.
Q: Which Crown pallet jack models does the 312021-003-A fit?
A: The 312021-003-A is engineered as a direct replacement for Crown pallet jack series models that utilize this load wheel assembly specification. Verify your model compatibility using the cross-reference numbers: CR312021-003-A, CR312021-003, 312021-003, or 312021-003A.
Q: What does 95A Shore hardness mean for this load wheel?
A: 95A Shore hardness indicates the polyurethane tread density and resistance to wear. This rating is typical for industrial load wheels and provides a balance between durability and floor grip. Higher Shore values offer greater hardness but may reduce traction in wet conditions.
Q: What are the cross-reference part numbers for the 312021-003-A?
A: Cross-reference part numbers include CR312021-003-A, CR312021-003, 312021-003, and 312021-003A. These reference numbers help ensure you obtain the correct replacement for your Crown equipment.
Q: What makes the integrated shoulder bearing configuration beneficial?
A: The integrated shoulder bearing is pre-aligned and self-contained, reducing assembly complexity and minimizing play during operation. This design improves load wheel stability and performance across your pallet jack applications.
