Self-Aligning Ball Bearing

Self aligning ball bearing has two structures: cylindrical hole and conical hole. The material of the cage is steel plate, synthetic resin, etc.


BCHH Self-Aligning Ball Bearings are expertly engineered to automatically compensate for shaft 

misalignment and mounting inaccuracies, a critical feature developed through our 20+ years of bearing 

manufacturing experience. Operating under strict ISO 9001 certified quality systems, these bearings consist 

of two rows of balls running on a spherical outer ring raceway, allowing for ±2~3 degrees of misalignment 

adjustment. This unique design effectively reduces stress concentration, minimizes friction, and extends 

service life in challenging operating conditions where alignment precision is difficult to maintain.


Applications:

Agricultural machinery and implements

Textile manufacturing equipment

Conveyor systems and material handling equipment

Industrial fans and ventilation systems

Paper making machinery

Printing and packaging equipment
