Bearing Assembly

Frequently Asked Questions

Q: What does the C3 clearance designation indicate?
A: C3 clearance indicates internal radial clearance that is larger than standard (C0 or C1). This allows the bearing to operate with higher thermal expansion and is commonly used in heavy-duty applications where temperature fluctuations or sustained loads occur, such as manual pallet jack wheel assemblies under continuous use.

Q: Is the NT6205C3 compatible with manual pallet jacks from different manufacturers?
A: The NT6205C3 is a replacement bearing designed for standard manual pallet jack wheel assemblies across Crown, Toyota, Raymond, Yale, Hyster, and comparable equipment. Verify the bore diameter, outer diameter, and width match your specific equipment before ordering to ensure proper fitment.

Q: What maintenance does the NT6205C3 bearing require?
A: The NT6205C3 is a sealed bearing assembly that requires minimal maintenance. Inspect the bearing periodically for signs of noise, resistance, or leakage. Do not attempt to relubricate sealed bearings; replace the assembly when performance degrades or bearing play becomes excessive.

Q: How long does an NT6205C3 bearing typically last?
A: Bearing lifespan depends on load, frequency of use, and environmental conditions. Under normal warehouse duty cycles, expect 2 to 4 years of operation before replacement becomes necessary. Wet conditions, high ambient temperatures, or heavy sustained loads can reduce service life.
