small size angular contact ball bearings high precision internation standard

 Angular Contact Ball Bearings : There is contact angle between ferrule and ball, the standard angle are: 15º,30º,40º. The larger the contact angle the axial load capacity larger, the smaller angle is suitable for high speed revolution. Single row Bearings can sustain radial load and one-way axial load, DB combination,DF combination and double row bearings can sustain radial load and two-way axial load, DT combination is suitable for the occasion which the single-way axial load is large and the rated load of one bearing is not enough. The sphere diameter of high speed ACH bearings is small and more ball count, they are mostly used for machine tool spindle; angular contact Ball bearings is suitable for high speed and high precision rotation, the structure are two back combined single row angular contact Ball Bearings which share the same inner ring and outer ring, they can sustain radial load and two-way axial load, there is closed type for no filling notch bearings.  Main application:    Double row: oil pump,roots blower,air compressor,various variator,fuel injection pump,printing machinery.      inner structure  and cage material

    Type:
1). Single row angular contact ball bearings
2). Double row angular contact ball bearings
3). Four-point contact ball bearings Mounting
/DB: Mount in duplex, back to back
/DF: Mount in duplex, face to face
/DT: Mount in duplex, tandem    Four- point contact angular ball bearings: It can sustain radial load and two-way axial load. Single bearing can replace front combined or back combined angular contact ball bearings. Suitable for sustaining pure axial load or complex load which has the larger axial load, this type bearings can form a contact angle whichever direction axial load it sustains (a), so the ferrule and ball can always contact on double-dealing point of any contact line.   Main cage : copper alloy cage Main application : jet engine of airplane,gas turbine.
