BA 9503003550

Frequently Asked Questions

Q: What are the specifications of the BA 9503003550 bearing?
A: The BA 9503003550 is a Baker OEM ball bearing with a 20 mm bore diameter, equipped with two rubber shields for contamination protection. It is designed for manual pallet jack wheel and load assemblies requiring precision and durability.

Q: What manual pallet jacks does this bearing fit?
A: The BA 9503003550 is confirmed as an OEM bearing for Baker model 6600 manual pallet jacks. Before ordering, verify your equipment model and axle bore diameter to ensure correct fitment. Bearing size is not interchangeable between models.

Q: Why are the rubber shields important?
A: The two rubber shields protect the rolling elements and raceways from dirt, moisture, and chemical splash. This is critical in warehouse environments where floors are wet-cleaned or exposed to salt. Sealed bearings extend service life by preventing contamination from reaching the bearing races.

Q: How long will the BA 9503003550 bearing last?
A: With proper installation and normal manual pallet jack duty, expect 6 to 10 years of service life. Cold storage facilities may see longer life due to lower ambient temperatures reducing wear rates. Wet floor or outdoor use may reduce lifespan to 4 to 6 years due to moisture ingress.

Q: What causes this bearing to fail?
A: Bearings fail when water penetrates the rubber shields, contamination compromises the race surfaces, the bearing is overloaded beyond design limits, or the axle is misaligned. Impact damage to the outer race or shock loads during load drops accelerate failure.

Q: What are the failure symptoms?
A: Listen for grinding, clicking, or rough rotation sounds when the wheel turns. Feel for binding or drag when pushing the pallet jack freely. Observe excessive wheel play or axial movement on the axle. A bearing with a failed seal will show water residue or rust inside the wheel hub.
