High quality electric bicycle self- aligning ball bearing 1209

Details of self- aligning ball bearing

1.self-aligning ball bearings can be automatically compensated coaxiality error due to shaft deflection and shell deformation.
2.self-aligning ball bearings mainly withstand pure radial load,can take a little axial load at the same time support radial load,usually not used to bear pure axial load,if must take pure axial load,only stress in single row ball.
3.the inner,outer ring relative inclination not more than 3 degrees.
4.self-aligning ball bearings is widly used to take heavy load and shock load,precision instruments,low noise motor,automobile,motorcycle,metallurgy,rolling mill,mine,oil,papermaker,cement,sugar industry etc.
