Frequently Asked Questions
Q: What is the 4081688 and how is it constructed?
A: The HY 4081688 is a load roller assembly featuring Durarun 95A polyurethane tread permanently bonded to an industrial steel core with a pre-mounted bearing. Bonded construction eliminates tire separation risk and ensures unified performance throughout the wheel's service life.
Q: What equipment is the 4081688 designed for?
A: The HY 4081688 is a direct replacement load wheel assembly for Hyster electric pallet jacks, specifically compatible with Hyster W-series walkie models. Verify your equipment model and serial range before ordering to ensure fitment.
Q: What does 95A Durarun polyurethane provide?
A: Durarun 95A at 95 Shore A hardness balances wear resistance with rolling efficiency. It resists abrasion on concrete and sealed warehouse floors while maintaining smooth operation under typical load conditions. This hardness is standard for electric lift truck load wheels.
Q: How long does the 4081688 typically last in service?
A: Under normal warehouse conditions, this wheel assembly typically serves 12-24 months. Service life varies with load cycles, floor type, and maintenance. Replace when tread wear exceeds 10% diameter loss, visible out-of-round develops, or bearing noise appears.
Q: Is the 4081688 maintenance-free?
A: Yes, the pre-mounted bearing is designed for maintenance-free operation. Periodically inspect bearings for noise or roughness during routine equipment checks. Replace the assembly if bearing performance degrades to maintain safety and reliability.
