BA 948076

Frequently Asked Questions

Q: What is the BA 948076 bearing and what does it fit?
A: The BA 948076 is a sealed ball bearing with two rubber shields designed for manual pallet jack wheel assemblies. It is an OEM part for Baker manual pallet jacks. The sealed design provides contamination protection, making it suitable for both indoor and outdoor storage environments.

Q: What do the rubber shields do?
A: The two rubber shields seal out dirt, moisture, and chemical contamination while allowing the bearing to spin freely. This extends bearing life by protecting the rolling elements and raceways. The shields are not removable without damaging the bearing.

Q: What are the bore diameter and load specifications?
A: Consult the bearing specification data for exact inner diameter, outer diameter, and width. Baker bearing part numbers encode these dimensions. The load rating supports typical manual pallet jack operating loads when properly installed in wheel hubs designed for this bearing series.

Q: How long will this bearing last?
A: With normal manual pallet jack use and dry storage, expect 5 to 8 years of service life. Cold storage or wet floor environments may extend life due to reduced temperature-related wear. Heavy-use warehouses with constant handling may require replacement every 3 to 5 years.

Q: What causes bearing failure and what are the symptoms?
A: Bearings fail due to water intrusion past the shields, inadequate lubrication inside the sealed unit, overloading, or impact damage. Symptoms include grinding noise, rough rotation, wheel drag, or axial play. A damaged seal will allow water to degrade the bearing race and rolling elements.

Q: Can I cross-reference this bearing to another part number?
A: The BA 948076 is confirmed as an OEM Baker part. No verified cross-reference part numbers are available from manufacturer or authorized distributor sources. Use the exact OEM number to ensure correct fitment.
