Correct installation and removal are key to ensuring bearing performance and service life. Improper handling can easily lead to damage to the raceways, deformation of the cage, or even premature failure.

Installation Points:

Clean Environment: Ensure that the shaft, bearing housing and tools are free of dust and burrs.

Fit Tolerances: Select the appropriate interference or clearance fit according to operating conditions; avoid forcing the bearing into place by hammering.

Heat Installation: For inner rings with an interference fit, induction heating to 80–120°C is recommended (open flames are prohibited); after uniform expansion, slide the ring onto the shaft shoulder.

Apply Force Evenly: Use specialised press-fitting tools; pressure should be applied to the ring with the interference fit (e.g., apply force to the inner ring when installing the inner ring).

Key points for disassembly:

Cold removal is preferred: Use a puller or hydraulic removal tool; avoid hammering.

Heat assistance: If rust has caused the bearing to seize, the bearing housing (outer ring) may be locally heated to expand it before removal.

Protect components: Take care not to damage the surface of the shaft or bearing housing during disassembly, as this may affect the accuracy of the next installation.

Note: For precision equipment (such as motors and machine tool spindles), it is recommended to use professional tools equipped with temperature measurement and positioning functions, and to record installation parameters for maintenance traceability.

Proper operation yields twice the result with half the effort — one correct installation is better than ten repairs.
