Frequently Asked Questions
Q: What equipment type is the 608870 bearing assembly designed for?
A: The 608870 is a bearing assembly for manual pallet jack and hand truck wheel replacement. It is compatible with standard wheel hubs used on manual material handling equipment from Crown, Toyota, Raymond, Yale, and similar OEM brands. Confirm your equipment model and wheel hub specifications to ensure fitment compatibility.
Q: Is the 608870 pre-lubricated and sealed?
A: Yes. The 608870 bearing assembly is factory sealed and pre-lubricated with bearing grease. It requires no additional preparation before installation and does not need manual lubrication at the time of replacement. The sealed design protects against floor contaminants and moisture ingress during warehouse operations.
Q: How long does a 608870 bearing assembly typically last in service?
A: Under normal warehouse conditions on manual pallet jacks, the 608870 bearing assembly typically operates for 18 to 36 months before replacement becomes necessary. Service life varies based on load patterns, floor conditions, and frequency of use. High-traffic areas with frequent cycle loading or rough floors may require earlier replacement.
Q: What symptoms indicate the 608870 bearing assembly is failing?
A: Signs of bearing failure include grinding or rough rolling noise when the wheel rotates, increased resistance requiring greater manual effort to push the pallet jack, visible wheel wobble or side play, and discoloration or corrosion visible on the bearing outer surfaces. Any of these conditions warrant bearing replacement to prevent wheel hub or load wheel damage.
Q: Can the 608870 bearing assembly be refurbished or must it be replaced as a complete unit?
A: The 608870 is designed as a sealed, factory-assembled bearing unit and is replaced as a complete assembly. Disassembly is not recommended because the bearing races are precision-matched at manufacture and seals are factory set to retain lubrication. Replacement ensures consistent performance and bearing life specifications.
Q: What dimensions should I verify before ordering the 608870 bearing assembly?
A: Before ordering the 608870, confirm the bore diameter, outer diameter, and width of your current bearing assembly or wheel hub specifications. Also verify the wheel hub bolt pattern and any mounting surfaces. Compare these dimensions to the 608870 specifications to ensure fitment with your pallet jack model.
