Mast bearing
Frequently Asked Questions
Q: Which forklift models use mast bearing 800010731?
A: This mast bearing fits electric and internal combustion forklifts from Toyota, Crown, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. The mast bearing supports the load wheels and lateral movement of the mast. Confirm your forklift model and mast stage before ordering.
Q: What are the bore diameter and width specifications for this mast bearing?
A: Mast bearing dimensions vary significantly by forklift manufacturer and mast stage. Provide your forklift model, serial number, and mast height range to us, and we will confirm the exact bore, outer diameter, and width. Incorrect dimensions cause improper fit and lateral play.
Q: What is the load capacity and material of bearing 800010731?
A: Mast bearings use hardened steel races and balls rated for the specific forklift tonnage class. The load rating depends on bearing size and ball diameter. Overloading or using a lower-capacity bearing causes premature failure and safety hazards. Verify the tonnage class of your forklift.
Q: How long does a mast bearing typically last on a forklift?
A: Mast bearings in heavy-duty use typically last 2-4 years, depending on load, operating hours, and lubrication maintenance. Forklifts with proper greasing intervals experience longer bearing life. Symptoms of wear include lateral play in the mast, binding during tilt, or grinding noise.
Q: What causes mast bearing failure and how do I diagnose it?
A: Common causes are inadequate lubrication, overloading, and impacts during operation. Signs of failure include loose play in the mast, resistance to lateral tilt, metal particles in the grease, or audible grinding during movement. Inspect the bearing raceway for spalling or corrosion.
