Frequently Asked Questions
Q: What does single-shield mean on the 43204 bearing?
A: Single-shield means the 43204 has a protective cover on one side of the bearing races. This provides some protection against dust and debris while allowing partial ventilation. It is less protective than sealed bearings but more protective than open designs.
Q: Which pallet jack models use the 43204 single-shield bearing?
A: The 43204 single-shield bearing fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers where single-shield protection is specified. Verify your equipment documentation to confirm this is the correct shield type for your jacks.
Q: What are the bearing material specifications for the 43204?
A: The 43204 uses hardened chromium steel (SAE 52100 grade) races and balls with a steel cage. This provides the durability needed for warehouse pallet jack applications supporting both load and steering functions.
Q: Should I use the 43204 or the sealed 43204-TT?
A: Use the 43204 single-shield for dry indoor warehouse environments. Use the 43204-TT sealed bearing if your facility uses floor washing, operates in wet storage, or has high humidity. Check your equipment specifications to confirm which type your pallet jacks require.
Q: How do I know when a 43204 bearing needs replacement?
A: Replace the bearing when wheels exhibit dragging resistance, grinding noise, excessive play or wobble, or when steering becomes stiff. These indicate internal wear that affects pallet jack performance and safety.
