Frequently Asked Questions
Q: What is a bearing assembly used for on lift trucks?
A: The 631685 bearing assembly supports and reduces friction on rotating shafts and components. In lift trucks, bearing assemblies support load wheel spindles, steering assemblies, and transmission shafts.
Q: Which lift truck models use this bearing assembly?
A: The 631685 is compatible with internal combustion and electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other OEM manufacturers. Cross-reference your equipment model and serial number to verify compatibility.
Q: What causes bearing assembly failure?
A: Bearing assemblies fail due to lack of lubrication, contamination from dirt and debris, impact damage from rough handling, or excessive load. Failed bearings produce grinding noise, vibration, and resistance in steering or load wheel rotation.
Q: How long does a bearing assembly typically last?
A: Bearing assembly lifespan depends on maintenance, operating conditions, and equipment usage. Well-maintained bearings last thousands of hours. Bearings in contaminated environments or with inadequate lubrication fail much sooner.
Q: What symptoms indicate a failing bearing assembly?
A: Failing bearings produce grinding or squealing noise, excessive vibration, hard steering, or binding of load wheels. Early warning signs include reduced smooth operation and intermittent noise during load handling.
