Bearing Assembly Single Shield

Frequently Asked Questions

Q: What does single shield mean on the 30-A-164 bearing assembly?
A: Single shield indicates one side of the bearing assembly has a protective metal or plastic shield. The 30-A-164 single shield design provides contamination protection on one side while allowing direct access or grease application on the opposite side, common on manual pallet jack load wheels.

Q: What equipment is the 30-A-164 bearing assembly compatible with?
A: The 30-A-164 single shield bearing assembly fits manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster. Verify your equipment model and wheel position to confirm compatibility before ordering.

Q: Is the 30-A-164 sealed or does it require periodic maintenance?
A: Single shield bearings like the 30-A-164 provide moderate protection but are less sealed than fully shielded or sealed bearings. They may require periodic lubrication depending on operating environment and manufacturer recommendations. Check your equipment manual for maintenance intervals.

Q: What bearing bore size does the 30-A-164 assembly have?
A: The bearing bore size on the 30-A-164 assembly varies by application. Contact us with your specific pallet jack model and wheel type to confirm the bearing bore diameter, hub length, and other dimensional specifications.

Q: What is the difference between single shield and double shield or sealed bearings?
A: Single shield bearings have one protective cover; double shield have two; sealed bearings have contact seals. Single shield allows easier relubrication but offers less contamination protection. Double shield and sealed designs are better for wet or harsh environments. Choose based on your operating conditions.

Q: Are there OEM cross-references or equivalent part numbers for the 30-A-164?
