Frequently Asked Questions
Q: What are the key specifications for the CR 310178 Polyurethane Load Roller?
A: The tread is durable 95A polyurethane in standard compound formulation.
Q: Which equipment brands is the CR 310178 compatible with?
A: The CR 310178 is a Crown direct replacement part designed for Crown electric pallet jacks and stackers. It also cross-references to Raymond equipment, including Raymond 115 and 632-014-001 models.
Q: What do the superseded part numbers mean?
A: The CR 310178 replaces earlier Crown part numbers 310178-301 and 310178-302. If your equipment uses those older numbers, the CR 310178 is the current equivalent part.
Q: What is the significance of the bore diameter specification?
A: The shaft opening size that mounts onto your equipment's axle. This dimension must match your pallet jack or stacker axle exactly to ensure proper fit and function.
Q: Why is the bore depth important?
A: Indicates how deep the bearing pocket extends into the wheel. This measurement is critical for proper wheel seating on the axle assembly and prevents misalignment.
Q: How does the 95A polyurethane hardness affect wheel performance?
A: Shore A 95A is a medium-hard polyurethane compound that balances durability with floor protection. This hardness level provides excellent load capacity while maintaining control and stability in warehouse applications.
Q: What makes the tread width significant?
A: The wide tread distributes load across a larger contact area, reducing point pressure on floors and providing stable support during load handling operations on pallet jacks and stackers.
Q: Can I use the CR 310178 as a direct replacement for Raymond equipment?
A: Yes, verify that your Raymond equipment requires the exact bore diameter and outside diameter before ordering. Cross-references to Raymond 115 and 632-014-001 confirm compatibility.
