Frequently Asked Questions
Q: What are the material and hardness specifications for the HY 4081687-XL?
A: The HY 4081687-XL is a polyurethane load wheel assembly with 97A Shore A hardness and features lubricated stainless steel bearings. The higher 97A hardness provides increased wear resistance compared to standard 95A wheels, making it suitable for higher-cycle operations or abrasive floor conditions.
Q: Why does the HY 4081687-XL use stainless steel bearings?
A: Stainless steel bearings resist corrosion and extend bearing life in washdown environments, cold storage, or humid conditions. The HY 4081687-XL is pre-lubricated, so bearings are sealed for maintenance-free operation. This specification is common in OEM Hyster electric lift truck wheels designed for demanding warehouse conditions.
Q: What Hyster lift truck models use the HY 4081687-XL?
A: The HY 4081687-XL is designed for select Hyster electric lift truck models. To confirm compatibility, verify your equipment serial number and consult Hyster technical documentation or provide your model number and current part number. The XL designation indicates a specific dimensional or bearing variant within the Hyster product line.
Q: How does the 97A hardness of the HY 4081687-XL affect wear compared to 95A wheels?
A: The 97A compound is slightly harder than standard 95A, resulting in slower wear rates and longer service life, typically 18 to 30 months under normal use. The tradeoff is marginally reduced grip on smooth or slippery floors. For high-cycle operations or abrasive floors, the extended durability of 97A justifies this design choice.
Q: What is the rated load capacity of the HY 4081687-XL wheel assembly?
A: Load capacity is defined by the complete Hyster electric lift truck system, not by the wheel alone. Wheel performance is rated within the equipment assembly context. Refer to your Hyster lift truck manual or technical documentation for rated load limits and operating specifications.
Q: Can stainless steel bearing wheels be used in cold storage or washdown environments?
A: Yes. The stainless steel bearings on the HY 4081687-XL are corrosion-resistant and pre-lubricated, making them suitable for cold storage and washdown areas. The polyurethane tread maintains grip at low temperatures. However, verify that the 97A hardness provides acceptable traction on wet or icy surfaces for your specific application.
