Frequently Asked Questions
Q: What are the key specifications of the RL 3-91003-A load roller assembly?
A: The RL 3-91003-A is a load wheel featuring ultra-poly tread, aluminum alloy hub, and four flanged ball bearings.
Q: Which Rol-Lift models use the RL 3-91003-A?
A: The RL 3-91003-A is compatible with Rol-Lift Series T and Series E manual pallet jacks. Cross-reference numbers include RL3-91003, RL391003, and 391003. Verify your equipment model before ordering.
Q: What does the RL 3-91003-A-D designation mean?
A: The RL 3-91003-A-D is an obsolete variant that has been superseded. The current direct replacement is the RL 3-91003-A. Always confirm your equipment generation and serial range to ensure you order the correct part.
Q: What is the load capacity of this wheel assembly?
A: The RL 3-91003-A has a rated load capacity under standard warehouse duty with proper load distribution. Actual working capacity depends on load configuration, equipment condition, and bearing maintenance.
Q: Why does this wheel have four flanged bearings?
A: Four flanged ball bearings provide superior radial and axial load support for smooth rotation under heavy lifting cycles. The flanged design protects bearings from dirt and debris common in warehouse environments.
Q: What advantages does the aluminum hub provide?
A: Aluminum construction reduces overall wheel weight compared to steel while maintaining rigidity and strength. Aluminum also resists corrosion in damp warehouse and outdoor dock environments, extending bearing life and reducing maintenance needs.
Q: Why is the ultra-poly tread material preferred for load wheels?
A: Ultra-poly high-density polyurethane delivers excellent durability, floor protection, and noise reduction. This material withstands heavy compression and repeated lifting cycles while minimizing damage to flooring and providing consistent rolling characteristics.
