Frequently Asked Questions
Q: What are the dimensions and material composition of the PR 310147 load wheel?
A: The PR 310147 is a 3.25 inch diameter, 4.5 inch width load wheel. The tread is polyurethane with 95A durometer hardness bonded to a machined steel core. Pre-installed ball bearings and axle are included.
Q: Is the PR 310147 a direct fit replacement?
A: Yes. The PR 310147 is a direct replacement for Prime Mover BT electric lift trucks. Cross-reference part numbers include PR310147, PM310147, and 310147. Verify your equipment model is compatible before ordering.
Q: What makes the 95A durometer polyurethane suitable for load wheel applications?
A: The 95A durometer rating indicates a hard polyurethane compound that resists wear under sustained load and floor friction. This hardness provides durability on standard floors and moderate wear resistance, making it appropriate for warehouse electric pallet jacks.
Q: What is the expected service life of the PR 310147 wheel?
A: Service life depends on load, floor surface, and operating hours. Polyurethane wheels at 95A durometer typically remain serviceable for 2 to 4 years in moderate warehouse use. Inspect for flat spots, cracks, or bearing play as indicators of replacement need.
Q: Does the PR 310147 include bearings?
A: Yes. The PR 310147 assembly includes pre-installed ball bearings, axle, and fasteners ready for installation. No additional bearing kits are required.
