Frequently Asked Questions

Q: What is SKU 443873 and where is it used?
A: SKU 443873 is a manual pallet jack thrust bearing designed for steering or pump assemblies. The thrust bearing supports axial loads during steering operations and pump cycles. It is compatible with Crown, Yale, Raymond, Toyota, and similar manual pallet jack models.

Q: What is the function of a thrust bearing in a manual pallet jack?
A: SKU 443873 thrust bearing carries axial loads—forces pushing along the axis of rotation. In pallet jacks, it supports forces generated during steering inputs and pump operation. This allows smooth turning and reduces wear on the steering column or pump components.

Q: How do I diagnose if SKU 443873 is failing?
A: Failure symptoms include resistance or grinding during steering, difficulty turning the handle smoothly, or noise from the pump area. If the steering column or pump rotates with increased friction or plays loosely, the thrust bearing may be worn and require replacement.

Q: What OEM brands use SKU 443873?
A: SKU 443873 is compatible with manual pallet jacks from major OEM manufacturers including Crown, Yale, Raymond, Toyota, and Hyster. Verify your equipment model and year to confirm fitment before ordering.

Q: What material properties does SKU 443873 have?
A: SKU 443873 is a precision thrust bearing with hardened bearing races and rolling elements designed to withstand repeated steering and pump cycles under manual load conditions. The bearing is engineered for durability and low-friction performance in industrial warehouse environments.

Q: How long does SKU 443873 typically last?
A: Expected service life is 2 to 5 years under normal warehouse use with proper lubrication and maintenance. Frequent steering or high-use pump operations may shorten lifespan. Replace when resistance, noise, or visible play develops.
