Frequently Asked Questions
Q: What manual pallet jack models does the 7180775 bearing assembly fit?
A: The 7180775 single shield bearing assembly is used on manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other major OEM manufacturers. Confirm your pallet jack model, serial range, and wheel position before ordering.
Q: What does single shield mean on the 7180775 bearing assembly?
A: Single shield means the bearing has protective metal coverage on one side only, not a full seal. This design allows some bearing grease to migrate out over time while providing moderate protection against dirt and debris ingress.
Q: How long does the 7180775 bearing assembly typically last?
A: Lifespan depends on load, usage intensity, and environmental conditions. Shielded bearings typically last 2 to 5 years in normal warehouse use. Harsher environments or high-cycle operations may require more frequent replacement.
Q: What symptoms indicate the 7180775 bearing needs replacement?
A: Replace the bearing if you hear grinding or squeaking from the wheel, observe rough wheel rotation, see grease leaking or dried grease around the bearing, notice excessive wheel play, or if wheel movement is notchy or jerky.
Q: Is the 7180775 single shield bearing different from a sealed bearing?
A: Yes. Single shield bearings are not sealed and require periodic maintenance or re-lubrication to extend life. Sealed bearings contain more grease and provide complete environmental protection but cannot be serviced and must be replaced when worn.
Q: Are there sealed bearing alternatives to the 7180775?
A: Sealed or double-shield equivalents may be available for your pallet jack model. Sealed bearings cost more but provide longer life in wet or dirty environments. Contact us with your equipment model to explore alternatives and compare durability.
