Frequently Asked Questions
Q: What are the specifications for the MU 820039 bearing?
A: The MU 820039 is a 20MM bearing with a rubber shield. It is designed for manual pallet jack load wheel assemblies and provides protection against contamination while maintaining smooth rotation under load.
Q: Which pallet jack models use the MU 820039 bearing?
A: The MU 820039 is compatible with Multiton manual pallet jacks. Verify your load wheel assembly dimensions match 20MM before ordering, as bearing sizes vary across different equipment models and manufacturers.
Q: What does the rubber shield on this bearing do?
A: The rubber shield seals the bearing cavity to keep out dirt, moisture, and debris. This extends bearing life in warehouse and outdoor environments where dust and wet conditions are common.
Q: When should I replace the MU 820039 bearing?
A: Replace the bearing if you notice grinding noise, rough rotation, or the wheel does not spin freely. Worn bearings reduce load wheel performance and increase strain on the hydraulic system.
