Product Description
The RL-31-3-SUPER is a precision-molded polyurethane load roller assembly designed for Rol-Lift TE Series manual pallet jacks. Featuring a 3.25-inch nominal diameter with machined aluminum hub and double flanged bearings, this load roller delivers consistent rolling performance on concrete, tile, and sealed warehouse floors. The ultra-polyurethane tread distributes load over an increased contact patch, improving load capacity and extending roller service life.

Frequently Asked Questions
Q: What is the roller diameter and bearing configuration of the RL-31-3-SUPER?
A: The RL-31-3-SUPER features a 3.25-inch nominal roller diameter with double flanged ball bearings. The machined aluminum hub provides a precision mounting surface. The larger diameter compared to standard RL-31 rollers offers increased contact area and load distribution.
Q: Which Rol-Lift pallet jack models are compatible with the RL-31-3-SUPER?
A: The RL-31-3-SUPER is designed for Rol-Lift TE Series manual pallet jacks, including both Series T and Series E models. Verify that your pallet jack frame and axle configuration accommodate the 3.25-inch diameter and double flanged bearing assembly. Cross-reference numbers include RL-31-3, Rol-Lift RL-31-3, and RLRL-31-3.
Q: What does double flanged bearing mean and how does it benefit the RL-31-3-SUPER?
A: Double flanged bearings have flanges on both sides of the rolling elements, providing superior axial containment and lateral stability. This configuration minimizes end-play and wobble, ensuring smooth rolling and reducing radial stress on the bearing races during load handling.
Q: How does the ultra-polyurethane tread on the RL-31-3-SUPER perform in different floor conditions?
A: Ultra-polyurethane provides consistent grip and traction on concrete, tile, and sealed warehouse floors. The precision-molded tread resists floor damage and maintains rolling efficiency during load cycles. Performance may vary on extremely wet or icy surfaces depending on warehouse climate control.
Q: Why is the RL-31-3-SUPER larger than the standard RL-31?
A: The larger 3.25-inch diameter increases the contact patch with the floor, distributing load over a greater surface area. This design reduces rolling resistance, improves load capacity, and extends roller service life by decreasing per-cycle tread stress compared to smaller diameter rollers.
Q: What materials are used in the RL-31-3-SUPER hub and tread?
A: The hub is machined from aluminum with a natural finish, providing lightweight strength and corrosion resistance. The tread is precision-molded ultra-polyurethane, engineered for durability and consistent rolling performance in manual pallet jack applications.
