HY 4081637-XL

Frequently Asked Questions

Q: What durometer rating does the HY 4081637-XL use?
A: The HY 4081637-XL features a 97A polyurethane durometer rating, which is harder than standard 95A compounds. The 97A provides increased wear resistance and longer service life in high-cycle applications while maintaining adequate floor contact and stability.

Q: Why are stainless steel bearings specified on this wheel?
A: Stainless steel sealed bearings provide corrosion resistance in wet, cold storage, or high-humidity environments. They also reduce maintenance requirements and extend bearing life compared to standard sealed bearings in harsh operating conditions.

Q: What is the purpose of the integrated string guards?
A: Integrated string guards prevent rope, twine, and debris from wrapping around the axle and wheel assembly during operation. They reduce downtime caused by entanglement and protect the bearing seals from contamination.

Q: Is the HY 4081637-XL compatible with standard Hyster electric trucks?
A: The HY 4081637-XL is designed for industrial electric lift truck applications matching Hyster specifications. Verify your equipment model number and compare against the OEM specification to confirm compatibility before ordering.

Q: When should this load wheel be replaced?
A: Replace when tread wear reaches approximately 50 percent thickness, or immediately if you observe flat spotting, cracking, or damage to the polyurethane compound. The stainless steel bearings typically outlast the polyurethane tread in normal service.
