Frequently Asked Questions
Q: What are the full specifications of the PR 2103800-A load wheel assembly?
A: The PR 2103800-A is a complete OEM load wheel assembly with 4 inch diameter and 2 and 7/8 inch width. It features a Durarun 95A polyurethane tread, cast iron core, 25 mm ID precision bearings, and includes the axle and mounting hardware. The tread finish is machined.
Q: What BT Prime Mover models are compatible with the PR 2103800-A?
A: The PR 2103800-A is engineered as a factory OEM load wheel assembly for BT Prime Mover electric lift trucks. This assembly includes all necessary components (axle and mounting hardware) for direct replacement. Verify your truck model and serial range match Prime Mover specifications.
Q: Why is the 25 mm bearing ID important?
A: The 25 mm ID (inner diameter) bearing specification ensures compatibility with Prime Mover lift truck axle shafts and mounting assemblies. This size is standardized across the Prime Mover product line. A 25 mm ID bearing will not fit axles designed for different sizes, so verify your truck specifications.
Q: What is Durarun 95A polyurethane and how does it perform?
A: Durarun 95A is a premium polyurethane compound specified at Shore A 95 hardness. This formulation provides excellent load-bearing capability, abrasion resistance, and durability in heavy-duty material handling operations. It maintains consistent traction in typical warehouse environments and resists premature hardening.
Q: Does the PR 2103800-A assembly include hardware for installation?
A: Yes, the PR 2103800-A comes as a complete assembly with the axle and mounting hardware included. This is a direct replacement assembly designed to minimize downtime when replacing a worn wheel on your Prime Mover lift truck.
Q: How does cast iron core material compare to steel core?
A: The cast iron core in the PR 2103800-A provides strength, durability, and dimensional stability for precision bearing support. Cast iron resists wear and deformation under high load cycles typical of electric lift truck operations. It maintains bearing alignment throughout the wheel assembly service life.
