Bearing Assembly - Single Shield

Frequently Asked Questions

Q: What is a single-shield bearing and when do you need BR-545?
A: The BR-545 is a bearing assembly with a single metal shield that provides dust and contamination protection on one side. Single-shield design is used in manual pallet jack applications where one side of the bearing is exposed or where contact with the wheel hub requires a lower shield profile.

Q: Which manual pallet jacks use the BR-545 bearing?
A: The BR-545 is compatible with standard manual pallet jacks and hand trucks from brands including Crown, Yale, and Hyster. This bearing is used in load wheel and steer wheel applications. Confirm your specific model before ordering.

Q: What is the difference between single-shield and double-shield bearings?
A: Single-shield bearings have one metal shield, providing protection on one side only. Double-shield bearings have shields on both sides for maximum contamination exclusion. Single-shield designs like the BR-545 are lighter and allow easier bearing seating in applications where space is limited.

Q: How does environment affect BR-545 bearing life?
A: In clean, dry indoor warehouse environments, the BR-545 typically lasts 2 to 4 years. Outdoor use, wet floors, and contact with salt or corrosive materials significantly shorten lifespan. Regular inspection and timely replacement prevent wheel lockup and equipment downtime.

Q: Can I replace just the bearing in the BR-545, or must I replace the whole assembly?
A: The BR-545 is a complete bearing assembly. Individual bearing races and balls are not replaceable. When the BR-545 fails, replace the entire assembly. This approach ensures consistent performance and eliminates field failures from partial repairs.
