Frequently Asked Questions
Q: What is the PR 2103800-A load wheel assembly?
A: The PR 2103800-A is a complete load wheel assembly designed as a direct replacement for Prime Mover electric lift trucks. It features a wheel with Durarun 95A polyurethane tread, cast iron core, precision bearings, and includes the axle and mounting hardware for installation.
Q: What are the key material specifications?
A: The assembly features Durarun 95A polyurethane tread at Shore A 95 hardness, which provides excellent load-bearing capability, abrasion resistance, and durability. The cast iron core provides strength and dimensional stability for precision bearing support and resists wear under heavy-duty lift truck operations.

A: The PR 2103800-A is engineered for BT Prime Mover electric lift trucks. Verify your specific truck model and serial number range match Prime Mover specifications to ensure compatibility. Contact your equipment documentation or supplier to confirm fitment before ordering.
Q: Why is the bearing ID important?
A: The bearing specification ensures compatibility with Prime Mover lift truck axle shafts and mounting assemblies. This bearing size is standardized for this product line. Using a bearing with a different ID will result in incompatibility with your truck's axle configuration.
Q: Does this assembly come with hardware for mounting?
A: Yes, the PR 2103800-A includes the axle and all necessary mounting hardware. This is a complete direct replacement assembly designed to minimize downtime when replacing worn wheels on your Prime Mover lift truck.
Q: What is the service life of this wheel assembly?
A: The Durarun 95A polyurethane tread and cast iron core construction deliver long service life under typical warehouse and distribution center operations. Actual lifespan depends on load weight, floor conditions, usage frequency, and maintenance practices.
Q: How does cast iron core compare to other core materials?
A: Cast iron provides strength, durability, and dimensional stability for precision bearing support. It resists wear and deformation under high load cycles typical of electric lift truck operations and maintains bearing alignment throughout the assembly's service life.
