HY 4081700-XL

Frequently Asked Questions

Q: What bearing type is used in the HY 4081700-XL?
A: The HY 4081700-XL features sealed 97A bearings with integrated string guards. The sealed design protects bearings from contamination in warehouse environments, extending service life and reducing maintenance requirements.

Q: Which Hyster truck models is the HY 4081700-XL designed for?
A: The HY 4081700-XL is a direct replacement poly load wheel assembly designed for Hyster electric pallet jacks, specifically including W45Z HD models. Confirm your equipment model matches before ordering.

Q: What is the polyurethane tread durometer rating?
A: The HY 4081700-XL utilizes a high-durability polyurethane tread rated at 97A durometer hardness. This harder compound resists abrasion and provides extended tread life in demanding material handling applications.

Q: What function do the string guards serve?
A: The integrated string guards protect the bearing assembly from debris, dirt, and material strings that can wrap around wheel axles during operation. This reduces bearing contamination and maintenance downtime.

Q: How does the polyurethane wheel compare to other materials?
A: Polyurethane wheels offer excellent durability, better load capacity, and superior grip compared to rubber alternatives. The 97A durometer rating balances traction with abrasion resistance for warehouse and dock environments.

Q: What is the service life of this load wheel assembly?
A: Service life depends on load, floor conditions, and operating hours. The sealed bearings and high-durability polyurethane tread significantly extend operational life compared to standard assemblies. Regular inspection of bearings and tread wear is recommended for optimal performance.
