Frequently Asked Questions
Q: What is the thrust bearing DA B4-97 designed for?
A: The DA B4-97 is a thrust bearing assembly designed for Dayton model 4YX97 pallet jacks. It manages vertical load and axial forces at the mast base connection point, reducing friction and wear on the frame structure.
Q: Does the DA B4-97 fit other Dayton pallet jack models?
A: The DA B4-97 is engineered specifically for Dayton model 4YX97. Cross-compatibility with other Dayton models depends on frame design and mast base dimensions. Verify your equipment model and serial range before ordering.
Q: What material is the DA B4-97 thrust bearing made from?
A: This bearing assembly combines steel races with hardened rolling elements. The contact surfaces are engineered for high-cycle loading in material handling environments and resist deformation under sustained weight.
Q: When should the DA B4-97 thrust bearing be replaced?
A: Replace the DA B4-97 when you notice grinding noise during mast extension, visible axial play in the mast base, or rough rotation when the jack is under load. A worn bearing increases friction and can damage the mast guide rails.
Q: What is the typical lifespan of the DA B4-97?
A: The DA B4-97 typically lasts 3-5 years in moderate to heavy-use applications. Lifespan depends on load cycles, storage conditions, and regular lubrication. Bearing wear accelerates in environments with dust, moisture, or extreme temperatures.
