Frequently Asked Questions

Q: What are the specifications of bearing L5520001156?
A: Bearing L5520001156 is a precision deep groove ball bearing designed for manual pallet jack wheel axle applications. It features double rubber seals, carbon steel construction with a minimum hardness of 60 HRC (Rockwell), and accommodates 20 mm axle shafts. The bearing is rated for loads up to 5,500 lbs and is pre-lubricated for standard material handling operations.

Q: Which manual pallet jack models does bearing L5520001156 fit?
A: This bearing is compatible with typical manual pallet jack configurations and fork tip wheel assemblies that use 20 mm axle shafts. Verify your equipment has a matching 20 mm bore specification before ordering. Cross-reference your equipment documentation with the OEM part number L5520001156 for compatibility confirmation.

Q: What does the double rubber seal provide?
A: Double rubber seals on bearing L5520001156 protect the ball races from contamination, moisture, and debris. This design extends bearing life in warehouse and material handling environments where exposure to dust, water, and particulates is common. The seals are integral to the bearing assembly and do not require separate maintenance.

Q: What load does bearing L5520001156 support?
A: Bearing L5520001156 is rated for loads up to 5,500 lbs in manual pallet jack wheel axle applications. This rating assumes proper axle alignment and distribution across the bearing assembly. Overloading beyond the rated capacity will reduce bearing life and may cause premature failure.

Q: How long does bearing L5520001156 typically last?
A: Bearing lifespan depends on load cycles, operating environment, and maintenance. Pre-lubricated double sealed units like L5520001156 typically provide 2-5 years of service in active warehouse operations. Performance degrades faster in wet or contaminated environments. Monitor for rough operation or unusual noise as signs of wear.

Q: Is bearing L5520001156 available under other part numbers?
A: The primary identifier is OEM part number L5520001156. Cross-reference with your equipment manufacturer documentation to confirm any alternate part numbers specific to your pallet jack model. No additional cross-reference numbers are currently documented for this bearing assembly.
