Bearing Assembly - Single Shield

Frequently Asked Questions

Q: What is the difference between single shield and double seal bearings like the APGP-2557?
A: The APGP-2557 features single shield protection on one side of the bearing. Single shield provides lighter contamination protection compared to double seals. Use single shield bearings when space is limited or when one side of the bearing faces an open mounting.

Q: What manual pallet jack models use the APGP-2557 single shield bearing?
A: The APGP-2557 is a single shield bearing assembly for manual pallet jacks. Confirm your pallet jack manufacturer and model to verify fitment, as single shield design is application-specific.

Q: What are the bore and outer diameter specifications for the APGP-2557?
A: Contact us with your pallet jack details for exact dimensional specifications of the APGP-2557. Bore size and outer diameter must match your equipment axle and wheel mounting to ensure proper fitment.

Q: When should I use a single shield bearing instead of a sealed bearing?
A: Single shield bearings are specified when installation space is tight or when one bearing side connects to an open area. For full contamination protection, double sealed bearings are preferred in typical warehouse conditions. Verify your equipment design specifications.

Q: How do I know if the APGP-2557 needs replacement?
A: Replace the bearing if you notice grinding noise, rough rotation, lateral play, or resistance during wheel operation. Single shield bearings may require more frequent inspection if used in dusty environments.
