Frequently Asked Questions
Q: What are the dimensions of the RL 3-91003-3 load wheel?
A: The RL 3-91003-3 features a 3-inch diameter, 3-3/4-inch width, and 1-3/4-inch tread thickness. These compact dimensions are ideal for manual pallet jack applications where space efficiency and maneuverability are important.
Q: Which pallet jacks is the RL 3-91003-3 compatible with?
A: The RL 3-91003-3 is engineered to fit Rol-Lift manual pallet jacks and select Crown PTH models. Cross-reference model numbers include 3910033 and 3 91003 3. It is a direct replacement for the discontinued RL 3-91003-A-D. Verify your equipment model matches before ordering.
Q: What is the load rating for this wheel assembly?
A: The RL 3-91003-3 features a high static load rating designed for heavy-duty industrial use. The exact capacity depends on load distribution and the complete jack assembly configuration. Contact the equipment manufacturer or our team with your complete model and serial number for precise specifications.
Q: What makes ultra-poly tread material suitable for pallet jack wheels?
A: Ultra-poly is engineered for material handling equipment, providing excellent wear resistance, superior floor protection, and reliable load durability in warehouse and dock environments. The tread meets ASTM D297 compliance standards for industrial applications.
Q: Does this wheel replace earlier Rol-Lift models?
A: Yes, the RL 3-91003-3 supersedes the discontinued RL 3-91003-A-D model with updated construction and materials. Both RL 3-91003-A and RL 3-91003-A-D refer to legacy designs. For modern compatibility, use the current RL 3-91003-3 part number.
Q: How should this wheel be maintained?
A: Inspect regularly for wear, cracks, or tread damage. Clean the tread of debris and buildup. Check that flanged bearings rotate smoothly with no binding or grinding sounds. Replace if tread thickness reduces significantly or cracks appear. Store in a dry area away from extreme heat.
Q: Is this a direct replacement part?
A: Yes, the RL 3-91003-3 is engineered as a direct replacement for the original equipment design, offering factory-specification compatibility with Rol-Lift and select Crown equipment. It meets all dimensional and performance requirements of the original component.
