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 a 6.00 inch diameter, 2.75 inch tread width, and 95A Shore hardness polyurethane tread. It features an integrated shoulder bearing configuration designed to reduce the need for installation spacers.
Q: Which Crown pallet jack models does the 312021-003-A fit?
A: The 312021-003-A is engineered for Crown pallet jack series models that utilize this load wheel assembly specification. Verify your model compatibility with the cross-reference numbers: CR312021-003-A, CR312021-003, 312021-003, or 312021-003A before ordering.
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: Does the 312021-003-A have cross-reference part numbers?
A: Yes. Cross-reference part numbers for the 312021-003-A include CR312021-003-A, CR312021-003, 312021-003, and 312021-003A. These reference numbers help ensure you get the correct replacement for your Crown equipment.
Q: How does the integrated shoulder bearing configuration improve performance?
A: The integrated shoulder bearing setup is pre-aligned and self-contained, reducing assembly complexity and the need for additional installation spacers. This design minimizes play and improves load wheel stability during operation.
