Frequently Asked Questions
Q: What are the key specifications of the CR 310160-035 load wheel?
A: The CR 310160-035 is a wheel with premium polyurethane tread rated Shore 97A hardness and a machined cast iron core. It is designed as a factory-spec direct replacement for Crown electric pallet trucks and walkie stackers. The wheel is compatible with standard 6006-2RS bearing assemblies.
Q: Why use a cast iron core instead of steel?
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 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 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 electric pallet jacks and walkie trucks?
A: Yes. The CR 310160-035 is engineered for factory-spec fitment on Crown electric pallet trucks and walkie-type stackers. 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.
Q: What maintenance is recommended for this load wheel?
A: Inspect the wheel regularly for wear, cracks, or damage to the polyurethane tread and cast iron core. Keep the bearing area clean and dry. Periodic lubrication of the 6006-2RS bearing assembly (if not sealed for life) will extend wheel life. Replace the wheel if tread wear becomes uneven or excessive, or if core damage is visible.
