Frequently Asked Questions
Q: What are the technical specifications of the RL 3-91003-A load roller assembly?
A: The RL 3-91003-A is a load roller assembly featuring a 3.25 inch diameter ultra-poly tread mounted on an aluminum alloy hub. It is equipped with four flanged ball bearings and is rated for 6500 lbs capacity. Width is 3-3/4 inches with 1-3/4 inch tread thickness. This assembly is engineered for durability in manual pallet jack applications.
Q: Which Rol-Lift pallet jack 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 part numbers include RL3-91003, RL391003, 391003, and 3-91003-A-D. The model designation is also listed as Series T. Verify your equipment generation and serial range matches before ordering.
Q: Is the RL 3-91003-A obsolete?
A: The RL 3-91003-A-D variant is obsolete and superseded by the RL 3-91003-3. However, the RL 3-91003-A itself remains a valid cross-reference for Series T and Series E equipment. For new orders, confirm whether your equipment requires the legacy RL 3-91003-A or the current RL 3-91003-3 replacement.
Q: What is the load capacity of the RL 3-91003-A?
A: The RL 3-91003-A has a rated load capacity of 6500 lbs. This rating applies under standard warehouse duty with proper load distribution across the pallet jack carriage. Actual working capacity depends on load configuration, equipment condition, and bearing maintenance.
Q: Why does the RL 3-91003-A have four flanged bearings?
A: Four flanged ball bearings provide radial and axial load support, ensuring smooth rotation and durability under heavy lifting cycles. The flanged design contains the bearing within the wheel hub, protecting it from dirt and debris common in warehouse environments. This bearing arrangement is standard for load wheels rated at 6500 lbs and above.
Q: What advantage does an aluminum hub offer on the RL 3-91003-A?
A: The aluminum alloy hub reduces overall wheel weight compared to steel construction while maintaining rigidity and strength for heavy loads. Aluminum also resists corrosion in damp warehouse or outdoor dock environments, extending bearing life and reducing maintenance frequency.
