HP-476

Frequently Asked Questions

Q: What is the HP-476 bearing assembly designed for?
A: The HP-476 is a single shield bearing assembly engineered for manual pallet jack load wheel and pivot applications. This bearing fits standard manual hydraulic hand trucks from Crown, Toyota, Raymond, Yale, and equivalent OEM manufacturers. The single shield configuration reduces drag while providing adequate debris protection for typical warehouse environments.

Q: What are the material specifications of the HP-476?
A: The HP-476 uses high-carbon chromium steel bearing races (AISI 52100 or equivalent), precision ground hardened steel balls, and a stainless or carbon steel open cage. The bearing is pre-lubricated and finished with an oil-protective coating to resist oxidation in warehouse and outdoor handling environments.

Q: How do I verify the HP-476 is compatible with my manual pallet jack model?
A: Verify bore diameter, outside diameter, and width measurements against your original bearing. Most manual pallet jacks use standard metric bearing sizes. Check your equipment documentation or the original bearing marking. If dimension specs match, the HP-476 will function as a direct replacement for load wheel or steer wheel positions.

Q: What is the typical service life of the HP-476 bearing assembly?
A: Under normal manual pallet jack usage, the HP-476 typically lasts 2000 to 4000 operating hours. Lifespan varies based on load weight, floor condition, and maintenance. Replace the bearing if you notice squeaking, grinding noise, wheel wobble, or increased rolling resistance.

Q: Why is the HP-476 single shielded instead of sealed?
A: Single shield design reduces friction and heat generation, important for manual equipment where lower operating loads make full sealing unnecessary. The shield prevents large debris from entering while allowing slight lubricant circulation. This design balances protection and performance for typical warehouse pallet jack use.

Q: Are there cross-reference part numbers for the HP-476?
A: The HP-476 is an OEM-equivalent bearing designed to replace original equipment bearing assemblies. Cross-reference compatibility depends on specific pallet jack model and year. Contact us with your equipment serial number for exact interchangeability confirmation and any available equivalent part numbers.
