Frequently Asked Questions
Q: What does the 383770 thrust bearing do in a forklift?
A: The 383770 thrust bearing is a specialized bearing that supports axial (up-down) loads in forklift mast assemblies. Unlike radial bearings, thrust bearings handle vertical load transfer when the mast raises or lowers, preventing metal-to-metal contact between shaft and housing.
Q: Which forklift equipment uses the 383770 thrust bearing?
A: The 383770 thrust bearing is used in Crown, Toyota, Raymond, Yale, Hyster, and other OEM forklift mast assemblies. Specific placement depends on mast design and load rating. Verify your equipment model and production year to confirm compatibility.
Q: What are the bore diameter and load capacity of the 383770?
A: The 383770 has a specific bore diameter and dynamic/static load rating engineered for forklift duty. These specifications ensure the bearing handles peak mast loads without premature failure. Contact us with your equipment details to confirm exact ratings.
Q: How do I diagnose a failing 383770 thrust bearing?
A: Signs of thrust bearing failure include knocking or clicking sounds during mast raise or lower, excessive vertical play in the mast assembly, or rough rotation. If the bearing spins roughly by hand or exhibits excessive play, replacement is required.
Q: What maintenance extends the life of the 383770 thrust bearing?
A: Thrust bearings require adequate lubrication and freedom from contamination. Regular mast inspection for debris, maintaining proper alignment, and avoiding overloading extend service life. Most thrust bearings in forklift service last 3-5 years with proper maintenance.
