Frequently Asked Questions
Q: What are the dimensions of the 4522-04621 industrial wheel?
A: Verify measurements against your equipment specifications before ordering.
Q: What is the Durarun compound and what durometer hardness does the 4522-04621 have?
A: The 4522-04621 uses Durarun polyurethane compound rated at 95A Shore durometer hardness. Durarun is an industrial polyurethane formulation that resists abrasion, tearing, and compression set. The 95A hardness provides load capacity and durability for heavy warehouse equipment while maintaining floor grip.
Q: Is the 4522-04621 a direct replacement for Mitsubishi part 4522-04621-SMH?
A: Yes, the 4522-04621 is a direct replacement for Mitsubishi part 4522-04621-SMH. No superseding part numbers or alternative cross-references have been identified. Fitment is guaranteed for Mitsubishi electric lift truck applications when dimensions and bore size match your equipment.
Q: How does 95A durometer hardness compare to softer polyurethane wheels?
A: 95A durometer is a medium-hard compound ideal for heavy load and high-frequency warehouse use. Compared to softer compounds (80A-90A), the 95A provides less rolling resistance, greater load capacity, and slower wear. Trade-off is reduced shock absorption and slightly less floor grip on wet surfaces.
Q: What equipment is the 4522-04621 compatible with?
A: The 4522-04621 is designed for Mitsubishi electric lift trucks of the FB-series, including FB10P, FB14P, FB15P, and FB18P models. Verify your equipment make and model plate against these compatible models before ordering. Confirm wheel dimensions match your axle specifications.
Q: Should I store this wheel in any particular way?
A: Store the 4522-04621 wheel in a cool, dry location away from direct sunlight and extreme heat. Avoid storage near oils, solvents, or ozone-generating equipment, as these can degrade polyurethane compounds over time. Keep wheels in their original packaging until installation.
