1,Double row self-aligning ball bearing outer ring raceway is spherical design.
2,steel stamping cage , brass and nylon cage design3,Adopting high precision rolling element G6、G8、G10 depand on your requirement.4,simple structure desgin can adapt to high-speed self-aligning operation。5,self-aligning ball bearingCan withstand Bi- axial and radial load,6,For double row self-aligning ball design designs can be aligning the maximum angle of 4º,Sealed bearings up to 1.5º.
.7,self-aligning ball bearing 12,13,22,23 series in both cylindrical and tapered bore two designs.8,self-aligning ball bearing has many internal meridional clearance，C2,CN,C3,C4 etc.9,Whole bearing adopt high quality chrome steel , chrome molybdenum steel,nickel-chromium -molybdenum steel , using fine steel carburizing hardened tissue suitable hardness.10,on both sides of the series 12 and 13  no dust cover，on both sides of the series 12 and 13 no dust cover，widely used，Due to the filling high quality oil suitable for any temperature work , increased bearing service life.11,Double row self-aligning ball bearing Most suitable for high speed ,low noise,self-aligning.
