Frequently Asked Questions
Q: What are the key specifications of the CR 310160-035 load wheel?
A: The CR 310160-035 is a 3.25 inch diameter wheel with 4.4 inch hub, premium polyurethane tread rated Shore 97A, and a machined cast iron core. It is designed as an OEM Crown replacement for electric pallet trucks and walkie lift trucks. The wheel is compatible with standard 6006-2RS bearing assemblies.
Q: Why use a cast iron core instead of steel on the CR 310160-035?
A: Cast iron core construction in the CR 310160-035 provides excellent rigidity, dimensional stability, and resistance to load-induced flex. Machined cast iron offers superior wear characteristics on the bearing surfaces compared to steel and reduces cost while maintaining performance. This core type is preferred for heavy-duty warehouse and dock lift truck applications.
Q: What does the 6006-2RS bearing compatibility mean?
A: The CR 310160-035 is designed to work with standard 6006-2RS deep groove ball bearings. The 6006-2RS designation indicates 30 mm bore, 55 mm outside diameter, and sealed closure (2RS = rubber sealed on both sides). Verify that your existing bearing meets this specification before ordering the wheel.
Q: Is the CR 310160-035 suitable for both pallet jacks and walkie trucks?
A: Yes. The CR 310160-035 is engineered for direct OEM fitment on Crown electric pallet trucks and walkie-type lift trucks. The 97A Shore polyurethane tread and cast iron core support the load and duty cycle characteristics of both equipment types. Confirm your specific Crown model and bearing compatibility before ordering.
Q: How does Shore 97A hardness perform compared to softer polyurethane compounds?
A: Shore 97A is a harder compound that offers superior wear resistance, reduced rolling resistance, and extended tread life under continuous use. The trade-off is slightly less floor protection and impact absorption compared to softer compounds like 95A. For warehouse-intensive applications, the 97A hardness of the CR 310160-035 provides better value through extended service life.
