Frequently Asked Questions
Q: What is a thrust bearing and what does the 220023558 do?
A: The 220023558 is a thrust bearing designed to handle axial loads, meaning forces that push along the shaft axis rather than perpendicular to it. In manual pallet jacks, thrust bearings are used in hydraulic pump assemblies and lift mechanisms to support vertical load during raising and lowering.
Q: What manual pallet jack equipment uses the 220023558 thrust bearing?
A: The 220023558 is used in manual pallet jack hydraulic systems. It supports the pump or lifting mechanism under vertical load. Verify compatibility with your equipment by checking your parts manual or equipment model. Standard pallet jacks from common OEM brands use similar thrust bearing designs.
Q: How do I identify a failing thrust bearing?
A: Symptoms of thrust bearing failure include resistance or drag when pumping the jack handle, grinding or clicking sounds during lift operation, excessive heat in the pump area, or jerky lifting action. If the bearing races are damaged, the jack may lift unevenly or not at all.
Q: What is the difference between a thrust bearing and a radial bearing?
A: A radial bearing handles loads perpendicular to the shaft (side loads), while a thrust bearing handles axial loads along the shaft. Thrust bearings use flat races and ball or roller elements arranged to resist pushing forces. In pallet jacks, thrust bearings prevent upward movement of pump shafts during lift cycles.
Q: How often does the 220023558 thrust bearing require maintenance?
A: Thrust bearings are typically sealed and do not require regular lubrication. Inspect the bearing during routine maintenance by checking for noise, heat, or resistance during operation. Replace the bearing if you detect grinding sounds, excessive friction, or visible wear on the races. Lifespan depends on load intensity and operating environment.
