Single Shield Bearing Assembly for Pallet Jacks

Frequently Asked Questions

Q: What does the single shield design on the MS556034 bearing mean?
A: The MS556034 features a single shield on one side of the bearing assembly, providing partial protection against contamination and moisture while allowing easier access on the unshielded side for mounting or installation. This design is common for wheel bearings in manual and electric material handling equipment.

Q: Which manual pallet jack models use the MS556034 bearing?
A: The MS556034 is designed for manual pallet jacks from major manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify your equipment model and wheel axle specifications match the bearing bore, outer diameter, and width before ordering.

Q: What protection level does the MS556034 single shield bearing provide?
A: The single shield design protects against direct contamination entry while maintaining lower drag and heat generation compared to fully sealed bearings. This makes it suitable for typical warehouse and dock environments. For wet storage or chemical environments, confirm adequate protection level before use.

Q: Is the MS556034 bearing pre-lubricated?
A: The MS556034 arrives pre-lubricated and ready for deployment in pallet jack wheel applications. The single shield design allows some access to the bearing interior if future relubrication is required, though it is designed for extended operation under normal warehouse duty without additional maintenance.

Q: How does the MS556034 compare to fully sealed bearing designs?
A: The MS556034 single shield design offers lower operating temperature and friction compared to fully sealed or dual-shield bearings, resulting in smoother jack operation. Trade-offs include slightly less protection against water and dust ingress. Choose single shield for standard indoor warehouse use; select fully sealed variants for wet storage or harsh environments.
