Avoid Direct Hammering:
Avoid directly hammering the bearing during installation to prevent damage to the raceways or rolling elements.
Use dedicated installation tools or sleeves to ensure even force distribution.
Correct Orientation:
Thrust roller bearings have tight rings and loose rings. Ensure proper orientation during installation, with the tight ring fitted to the shaft and the loose ring fitted to the housing.
Fit Tolerance:
Ensure the dimensional tolerances of the shaft and housing bore meet design requirements to avoid excessive tightness or looseness.
Excessive tightness may cause inner ring deformation, while excessive looseness may cause bearing slippage.
Lubricant Selection:
Choose the appropriate lubricant based on operating conditions (e.g., speed, temperature, load).
Avoid mixing lubricants from different brands.
Prevent Contamination:
Maintain cleanliness during installation to prevent dust or contaminants from entering the bearing.
If the bearing is exposed to a contaminated environment, consider using seals or protective covers.
Axial Clearance:
Check the axial clearance after installation to ensure it is within the allowable range.
Insufficient clearance may cause overheating, while excessive clearance may cause vibration or noise.
Trial Run:
Conduct a trial run after installation to check for abnormal temperature, vibration, or noise.
If any abnormalities are detected, stop the machine immediately for inspection.
