Frequently Asked Questions
Q: What equipment does the 903285 sealed ball bearing assembly fit?
A: The 903285 is a 6204 series sealed ball bearing assembly designed for manual pallet jack load wheels and rollers. It fits multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, Clark, and other manufacturers that use 20 mm bore diameter wheels and rollers.
Q: What are the dimensions and material specifications for the 903285?
A: The 903285 is a 6204 series bearing with a 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. It is constructed from chrome steel that has been hardened and ground to precise tolerances. The bearing comes sealed on both sides to prevent contamination and retain lubrication.
Q: How do I verify this bearing is compatible with my equipment?
A: Verify compatibility by confirming your load wheel or roller uses a 20 mm bore. Check the existing bearing or wheel bore diameter against the specification sheet. Cross-reference your pallet jack model number with OEM documentation to confirm 6204 series bearing compatibility.
Q: What is the typical service life of the 903285 sealed bearing?
A: Under normal operation with proper wheel alignment and load distribution, the 903285 sealed bearing typically lasts 3 to 7 years. Lifespan depends on load weight, floor conditions, maintenance, and storage environment. Pallet jacks operated on smooth surfaces last longer than those used on rough or debris-laden floors.
Q: What are the symptoms of bearing failure?
A: Replace the bearing if you notice grinding or squealing sounds from the load wheels, excessive play or wobbling in the wheel, resistance during operation, or visible damage to the bearing assembly. A failed bearing compromises jack stability and lift accuracy.
Q: Does this bearing work on both manual and electric pallet jacks?
A: The 903285 is specified for manual pallet jack load wheels and rollers. While some electric pallet jacks may also use 6204 series bearings, verify your equipment manufacturer documentation before ordering to ensure correct fit and load rating.
