Frequently Asked Questions
Q: What is the PU B-1-22 thrust bearing?
A: The PU B-1-22 is a thrust bearing component used in the load arm pivot assembly of Pallet Mule manual pallet jacks. It supports and reduces friction on the load arm shaft, allowing smooth tilting and lowering of the forks. Also referenced as part designation B-1-22 or B122.
Q: Which pallet jacks use the PU B-1-22 thrust bearing?
A: The PU B-1-22 is designed for Pallet Mule model B-1-22 manual pallet jacks. Alternate model numbers include B122 and B 1 22. Check your parts diagram reference designation AA-30 CR to confirm correct component.
Q: What does a thrust bearing failure feel or sound like?
A: Failing thrust bearings produce grinding, squeaking, or grinding noises during load arm tilting. You may feel increased resistance or stiffness when lowering the load arms, or notice the forks do not tilt smoothly. These symptoms indicate bearing wear and warrant replacement.
Q: How long does a thrust bearing typically last?
A: Thrust bearing lifespan depends on duty cycle, frequency of tilting, and maintenance practices. Regular lubrication extends service life significantly. Bearings in continuous-duty applications typically wear out within 3-5 years, while lighter-duty usage may extend this to 7+ years.
