Frequently Asked Questions
Q: What are the dimensions and bearing specification for part 654300?
A: The 654300 is a 6204-2RS bearing assembly with 20 mm inner diameter, 47 mm outer diameter, and 14 mm width. It is constructed from SAE 52100 chrome steel with dual rubber seals and features NBR synthetic rubber seal material on both sides. Shaft tolerance h7 is recommended for proper mounting clearance.
Q: What manual pallet jack models use the 654300 bearing assembly?
A: The 654300 bearing assembly fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar OEM manufacturers using the 6204-2RS specification. It can be positioned in both wheel and load bearing locations on pallet jack assemblies. Verify your equipment bore and shaft diameter match the 20 mm inner diameter specification before ordering.
Q: Why does the 654300 use dual rubber seals instead of metal shields?
A: Dual rubber seals (2RS designation) provide better protection against dust, moisture, and contaminants in warehouse and outdoor pallet jack environments compared to open or single-seal designs. NBR synthetic rubber resists oils, coolants, and cleaning chemicals common in material handling areas. This extends bearing lifespan on floor-level equipment exposed to wet and dirty conditions.
Q: What is the expected service life of the 654300 bearing under typical use?
A: Under normal warehouse pallet jack duty with consistent 4000 to 5000 lb fork loads and adequate lubrication, the 654300 typically operates for 18 to 30 months before replacement is needed. Lifespan decreases in harsh environments such as wet storage, freeze-thaw cycles, or extreme thermal conditions. Replace immediately if binding, grinding noise, or excessive play develops.
