Bearing Assembly for Manual Pallet Jack

Frequently Asked Questions

Q: What bearing type is used in the 901773801 assembly for manual pallet jacks?
A: The 901773801 uses a sealed deep groove ball bearing construction manufactured from high carbon bearing steel. This sealed design protects the bearing from dust and moisture contamination common in warehouse and dock environments.

Q: What equipment does the 901773801 bearing assembly fit?
A: The 901773801 is an OEM bearing assembly for wheel and roller applications on manual pallet jacks. This assembly is compatible with multiple OEM brands including Crown, Toyota, Raymond, and Yale manual jack models. Verify your equipment serial range and model number match before ordering.

Q: Why is high carbon bearing steel used in the 901773801 assembly?
A: High carbon bearing steel provides superior hardness and load-carrying capacity required for constant-load manual pallet jack wheel applications. This material resists surface wear and deformation under repeated lift cycles and heavy load transfer on warehouse floors.

Q: What is the typical service life of the 901773801 bearing assembly?
A: The sealed bearing construction extends service life by preventing internal corrosion and contamination. In typical warehouse duty cycles with proper maintenance and lubrication, this assembly supports 2-5 years of operation before replacement becomes necessary.

Q: What maintenance does the 901773801 sealed bearing assembly require?
A: The sealed bearing design eliminates regular relubrication. Periodically clean around the bearing housing to remove dirt buildup. Do not attempt to disassemble or force additional grease into sealed bearings, as this can damage the seals and introduce contamination.
