Frequently Asked Questions
Q: What are the key specifications of the UL 1227-N load roller assembly?
A: The UL 1227-N features a 20mm bearing bore, glass-reinforced nylon tread and hub construction, and precision ball bearings for low-friction operation. The nylon material provides superior wear resistance compared to standard rubber or polyurethane alternatives in lift truck applications.
Q: Which pallet jack models use the UL 1227-N wheel assembly?
A: The UL 1227-N is compatible with manual pallet jacks featuring 20mm axle bore specifications and nylon-tread wheel assemblies. Confirm your equipment OEM part number matches UL 1227-N before purchase to guarantee fitment and rated load capacity.
Q: How does the ball bearing precision fit improve performance?
A: Ball bearing precision fit ensures minimal axial play and consistent rotational smoothness under rated pallet loads. This tight tolerance reduces vibration, lowers friction drag, and extends bearing life by preventing lateral movement that accelerates wear.
Q: Is glass-reinforced nylon more durable than polyurethane wheels?
A: Glass-reinforced nylon is harder and more resistant to flat-spotting, cracking, and abrasion than softer polyurethane formulations. However, nylon may be less suitable for extremely cold storage environments where brittleness can occur. Verify your application temperature range before ordering.
