Frequently Asked Questions
Q: Which manual pallet jack brands and models use the 12AL12 bearing assembly?
A: The 12AL12 bearing assembly fits manual pallet jacks from Crown, Toyota, Raymond, Yale, and Clark. This assembly is engineered for the load wheel axle in specific model generations. Confirm your equipment serial range matches this part number before ordering.
Q: What are the physical dimensions and bore specifications for the 12AL12?
A: The 12AL12 has a defined bore diameter and assembly length that must match your axle specifications. Incorrect bore size results in axle misalignment and premature bearing failure. Measure your current bearing assembly or provide your pallet jack model for exact dimension verification.
Q: What maintenance does the 12AL12 bearing assembly require?
A: Regular bearing lubrication extends service life to the full 3-5 year window. Keep contamination away from bearing areas on warehouse floors. Monitor load wheel movement monthly for increased friction or grinding sounds, which indicate worn bearings requiring replacement.
Q: What failure conditions indicate the 12AL12 needs replacement?
A: Replace the assembly if the load wheel shows excessive radial or axial play, does not spin freely, or produces grinding or squealing sounds. Water or dirt ingestion and corrosion of internal races also warrant replacement to prevent further equipment damage.
Q: How does the 12AL12 differ from the 12AL11A and 12AL12A variants?
A: The 12AL12 has a different bore diameter and ball complement compared to 12AL11A and 12AL12A. Each variant is optimized for specific pallet jack models and load ranges. Review your parts diagram or equipment manual to identify the correct assembly for your application.
