THRUST PLATE BEARING
Frequently Asked Questions
Q: What is the LF PR-8512 thrust plate bearing?
A: The LF PR-8512 is a thrust bearing component that supports vertical load and prevents axial movement in the hydraulic cylinder or pump assembly of a Lift-Rite pallet jack.
Q: Where is the LF PR-8512 thrust plate bearing located in a pallet jack?
A: The LF PR-8512 is typically mounted in the pump or motor assembly to handle radial and thrust loads during lift cycles. The exact location depends on the specific pallet jack model and hydraulic system design.
Q: What material and specifications does the LF PR-8512 have?
A: The LF PR-8512 thrust plate bearing is manufactured with hardened steel races and precision rolling elements to withstand continuous load cycles. The bearing is sized and rated for the pump displacement and maximum load of the pallet jack model it serves.
Q: What symptoms indicate the LF PR-8512 thrust bearing needs replacement?
A: Replace the bearing if you hear grinding, squealing, or knocking noise from the pump during operation, feel excessive vibration, or if the jack loses pressure and does not maintain load. These are signs of bearing wear or failure.
Q: How long does the LF PR-8512 thrust bearing last before wear?
A: Bearing lifespan depends on load cycles, lubrication, and operating conditions. Proper hydraulic fluid maintenance and regular filter changes extend bearing life. A typical bearing may perform 10,000 to 50,000+ lift cycles before wear requires replacement.
Q: Can the LF PR-8512 be replaced individually or must the entire pump be replaced?
A: The LF PR-8512 thrust bearing can be replaced individually if it can be accessed in your pump assembly. However, some pump designs require complete pump replacement. Consult the equipment documentation for your specific pallet jack model.
