Frequently Asked Questions
Q: What are the dimensions and specifications of the 312021 load wheel?
A: The 312021 is a Durarun polyurethane load wheel measuring 4.50 inches in diameter and 3.25 inches wide. It features a 95A durometer polyurethane tread bonded to a steel core with factory pre-installed double-shielded ball bearings. This configuration is designed for heavy-duty warehouse material handling equipment including electric pallet jacks.
Q: Which electric pallet jack models is the 312021 compatible with?
A: The 312021 is compatible with Crown PE 3000, Yale MPB 040 AB, Yale MPB 045 VG, Jungheinrich EJE120, Toyota 7HBE30, and Toyota 7HBW23 electric pallet jacks. It also fits comparable equipment from other major manufacturers. Always verify wheel diameter and width match your equipment before ordering. Contact us with your equipment model number to confirm fitment.
Q: What are the cross-reference and equivalent part numbers for the 312021?
A: The 312021 cross-references to GW2365, CR 312021-A, CA1342780, and 51064639. The 312021 is a direct replacement for GW2365 and supersedes 51064639. These are equivalent part numbers from different manufacturers and suppliers. Use 312021 as the primary part number, or provide your existing part number and we can verify compatibility.
Q: Why is 95A durometer polyurethane preferred for load wheels?
A: The 95A durometer rating provides optimal balance between grip and wear resistance for electric pallet jack load wheels. This hardness level resists flat-spotting and cracking under heavy continuous use while maintaining traction on concrete floors. The polyurethane compound absorbs shock loads common in warehouse operations, extending wheel life compared to harder elastomers.
Q: How long does a 312021 load wheel typically last in service?
A: In typical warehouse service with regular use, a 312021 should provide 12-18 months of useful service life. Actual lifespan depends on floor conditions, load weight, usage frequency, and equipment maintenance. Wheels operating on clean, smooth concrete last longer than those on rough or contaminated floors. Replace wheels when tread depth visibly reduces or if you notice increased vibration or noise during operation.
Q: What maintenance does the 312021 require?
A: The 312021 features factory pre-installed double-shielded ball bearings requiring no routine lubrication. Keep wheels clean and free of debris that could increase rolling resistance. Inspect bearing shields periodically for damage. If bearing noise increases or wheels become difficult to turn, the bearing or wheel assembly may need replacement. The sealed bearings are maintenance-free during normal operation.
