Frequently Asked Questions
Q: What are the exact dimensions and specifications of the PR 21058-00?
A: The PR 21058-00 is a factory load wheel for electric pallet trucks with 3.25 inch diameter and 4.5 inch width. It features a 95A hardness polyurethane tread over a steel core, sealed precision bearings, and includes installation hardware.
Q: Which Prime Mover electric lift truck models use the PR 21058-00?
A: The PR 21058-00 is designed exclusively for Prime Mover electric lift truck applications. Verify your specific equipment model and series to confirm compatibility. The 3.25 inch x 4.5 inch size is specific to certain Prime Mover truck designs, so measure your current wheel before ordering.
Q: Why is this wheel wider than the PR 21038-00 series?
A: The PR 21058-00 is 4.5 inches wide compared to 2.875 inches on the PR 21038-00. The wider wheel footprint is engineered for specific Prime Mover truck chassis designs. Wider wheels distribute load over a larger contact area, affecting weight distribution and truck stability. Do not substitute wheel widths without engineering verification.
Q: What bearing type is used in the PR 21058-00?
A: The PR 21058-00 uses sealed precision bearings. The sealed design protects the bearing cavity from dust, moisture, and contaminants common in warehouse and production environments. Sealed bearings require minimal maintenance compared to open-style bearings.
Q: How long does the 95A polyurethane tread last in normal use?
A: Tread lifespan depends on lift truck usage intensity, load weight, floor surfaces, and environmental conditions. The 95A polyurethane formulation is designed for extended durability in electric pallet truck operations. Replace the wheel when tread wear becomes uneven, when traction is visibly reduced, or when the truck begins showing handling changes.
Q: Does the PR 21058-00 come with installation hardware?
A: Yes, the PR 21058-00 is supplied with installation hardware included. This factory assembly is ready for deployment on Prime Mover electric lift trucks designed to accept this wheel size and specification.
