Bearing Assembly

Frequently Asked Questions

Q: What equipment type does the 6103248-08 bearing assembly fit?
A: The 6103248-08 is a bearing assembly for manual and electric pallet jack wheel replacement. It is compatible with standard wheel hub configurations used by major OEM brands including Crown, Toyota, Raymond, Yale, and Hyster. Verify your pallet jack model number and wheel hub bore diameter to confirm fitment before ordering.

Q: Is the 6103248-08 pre-lubricated?
A: Yes. The 6103248-08 bearing assembly is factory pre-lubricated with high-performance bearing grease and sealed to retain internal lubrication. No additional lubrication or assembly preparation is required at the time of installation. The sealed design protects the bearing against warehouse floor contaminants and moisture.

Q: What is the typical service life of the 6103248-08 bearing assembly?
A: Under normal warehouse duty cycles, the 6103248-08 bearing assembly typically operates for 18 to 36 months before replacement becomes necessary. Service life depends on load patterns, floor conditions, and usage frequency. High-traffic areas with frequent pallet movements or uneven floor surfaces may require earlier replacement.

Q: What warning signs indicate the 6103248-08 bearing assembly is worn?
A: Replace the 6103248-08 if the wheel exhibits grinding noise during rotation, rough rolling feel without noise, significant wheel wobble or side play, or visible discoloration and corrosion on bearing surfaces. These symptoms indicate internal wear, seal failure, or loss of lubrication. Continued operation can damage the wheel hub and increase load on adjacent components.

Q: Can the 6103248-08 bearing assembly be refurbished or repacked with grease?
A: The 6103248-08 is a sealed, factory-assembled bearing unit designed for replacement as a complete assembly only. Disassembly is not recommended because the bearing races are precision-matched at manufacture and the seals are factory set. The sealed design cannot be repacked. Replacement with a new bearing ensures consistent performance and specified service life.

Q: What critical dimensions must I verify before ordering the 6103248-08?
A: Before ordering the 6103248-08, confirm the bore diameter, outer diameter, width, and wheel hub mounting interface of your current bearing assembly or wheel hub. Also note the wheel hub bolt pattern and any keyway specifications. Cross-reference these dimensions to the 6103248-08 specifications to ensure proper fitment with your pallet jack model.
