Bearing Assembly Single Shield

Frequently Asked Questions

Q: What is the function of the 4320UTT bearing assembly?
A: The 4320UTT is a single shield bearing assembly that reduces friction and supports load on manual pallet jack masts. It enables smooth lifting and lowering operations in Crown, Toyota, Raymond, and Yale pallet jacks.

Q: Is the 4320UTT a single shield or open design?
A: The 4320UTT is a single shield bearing assembly. The shield covers one side for dust protection while the opposite side remains open for inspection and maintenance access.

Q: How do I confirm the 4320UTT is correct for my pallet jack?
A: Compare the bore diameter, outer diameter, and width of your current bearing against the 4320UTT specifications. Cross-reference your pallet jack model number against compatibility data. Contact technical support if you are uncertain about fitment.

Q: What is the typical service life of the 4320UTT?
A: With regular lubrication under normal warehouse conditions, expect 3 to 5 years of service life. Heavy use, inadequate maintenance, or continuous operation reduce longevity. Replace immediately if you observe grinding, vibration, or excessive play.

Q: What other bearing assemblies can be cross-referenced with the 4320UTT?
A: The 4320U-TT shares similar bore specifications but with open design. Models 43206-T and 43206P may serve related applications depending on exact dimensions. Always verify dimensional compatibility before cross-referencing part numbers.

Q: What materials are used in the 4320UTT bearing assembly?
A: The 4320UTT uses hardened steel races and ball elements for load support. The single shield is mild steel. These materials provide corrosion resistance and durability suitable for indoor warehouse material handling.
