Frequently Asked Questions
Q: What is the RL-31-3 wheel diameter and tread material?
A: The RL-31-3 features ultra-polyurethane tread rated at 92 Shore A hardness. This firm compound resists wear during heavy load cycles while maintaining excellent floor contact and grip.
Q: What type of bearings does the RL-31-3 use?
A: The RL-31-3 is equipped with flanged ball bearings in a sealed configuration. Flanges contain rolling elements to reduce lateral play and axial movement, improving alignment accuracy and reducing wobble during load handling.
Q: Why is 6061-T6 aluminum used for the RL-31-3 hub?
A: 6061-T6 aluminum provides excellent strength-to-weight ratio and superior corrosion resistance. The T6 heat treatment hardens the alloy for precision machining and load bearing, making it ideal for pallet jack components exposed to variable conditions.
Q: How do integrated alignment washers improve the RL-31-3 performance?
A: Integrated alignment washers maintain precise roller positioning on the axle, preventing axial drift and uneven tread wear. This centering function ensures smooth rolling and reduces operational friction, extending both roller and bearing service life.
Q: Which Rol-Lift manual pallet jack models are compatible with the RL-31-3?
A: The RL-31-3 is engineered for Rol-Lift Series manual pallet jacks. Verify your pallet jack model and axle bore specifications match the roller hub diameter. Cross-reference numbers include RL RL-31-3, Rol-Lift RL-31-3, RL RL31-3, and RLRL-31-3.
Q: How should I maintain the RL-31-3 load roller?
A: Periodically inspect the tread for excessive wear or damage. Clean the roller and bearing area of debris and moisture. Check bearing movement for excessive side play or grinding sounds. Store in a dry location. Replace when tread depth becomes uneven or bearing movement becomes loose.
