128468

Frequently Asked Questions

Q: What is the 128468 bearing assembly used for?
A: The 128468 is a steel thrust bearing assembly set designed for installation in hydraulic pump assemblies on manual pallet jacks. It includes a thrust bearing, washer, and retaining ring, functioning as a complete thrust load management system.

Q: What components are included in the 128468 bearing assembly?
A: The 128468 assembly consists of three elements: a precision-machined steel thrust bearing, a load-distribution washer, and a retaining ring. All components are machined steel, untreated. This three-part design distributes axial (thrust) loads across the pump assembly and prevents bearing migration during operation.

Q: Which manual pallet jack models use the 128468 bearing assembly?
A: The 128468 is a generic replacement bearing assembly for manual pallet jacks that use hydraulic pump systems with thrust bearing configurations. No specific OEM model cross-references are documented. Verify that your pump assembly uses a thrust bearing setup before ordering, and measure existing bearing dimensions to ensure compatibility.

Q: What materials and hardness specifications does the 128468 have?
A: All components of the 128468 are machined from steel in an untreated state. The bearing and washer are precision-finished for low-friction operation and load distribution. Untreated steel surfaces require protection from corrosion, especially if the pallet jack operates in wet, outdoor, or salt-exposure environments.

Q: How long does the 128468 bearing assembly last before replacement?
A: Lifespan depends on hydraulic system cleanliness and operating conditions. In well-maintained systems with regular fluid changes and filter replacement, expect 3-5 years of service. Contaminated hydraulic fluid or high-cycle operation may reduce lifespan. Replace if you observe noise from the pump, loss of lifting pressure, or visible wear or scoring on bearing surfaces.
