Bearing Assembly for Pallet Jacks

Frequently Asked Questions

Q: What is the dimensional tolerance for the A-750-12 bearing assembly?
A: Bearing assembly dimensions are precision-manufactured to specification tolerances. Verify the bore diameter, outer diameter, and width measurements from the product sheet match your equipment shaft and housing before ordering.

Q: Is the A-750-12 a single-row or double-row bearing assembly?
A: Check the product specification to determine row configuration. Double-row assemblies provide higher load capacity and different mounting requirements than single-row versions.

Q: How often should the A-750-12 bearing assembly be lubricated?
A: Lubrication intervals depend on bearing type and operating environment. Sealed bearings require no maintenance. Unsealed bearings typically need lubrication every 500 to 1000 operating hours. Check the specification sheet for exact recommendations.

Q: What happens if the A-750-12 bearing assembly is over-lubricated?
A: Excess grease causes heat buildup, accelerates seal wear, and reduces bearing lifespan. Follow the product specification for proper lubrication quantities and intervals.

Q: Can the A-750-12 be relubricated or must it be replaced when dry?
A: If the bearing assembly is designed as sealed-for-life, replacement is necessary when lubrication is depleted. If it features accessible grease fittings, relubrication is possible. Verify the bearing type in the specification.
