Open Type Single Row Angular Contact Ball Bearing , Machine Tool Bearing
Angular Contact Bearing
Like other bearings,angular contact ball bearings are also have lots of structures,single row angular contact ball
bearings can accommodate radial load and axial load in single direction.While double row angular contact ball
bearings in DB or DF combination and four-point contact ball bearings can accommodate radial load and axial
load in two directions.Angular contact ball bearings suit high-speed rotation and high-precision rotation.
These bearings are mainly used in the fields like machine tool spindles,high frequency motors,
oil pumps,air compressors,printing machines,etc.For four-point contact ball bearings are mostly used in
the roller-boxes of rolling mills to carry axial load.
Angular contact ball bearings:
7000C-type (α = 15 °), 7000AC-type (α = 25 °) and 7000B (α = 40 °) of several types. The kinds of bearings in the outer ring lock port, the general separation of inside and outside the ring can not be combined radial and axial load and axial load in one direction. Axial load capacity of the decision by the contact angle, contact angle is greater, the ability to withstand high axial
loads. This kind of bearing shaft or housing to limit axial displacement in one direction.
1 single row (open type)
70, 72, 73, 718, 719 Series
2 double row (open or sealed)
50, 52, 53, 54 series,
32, 33 series
3 Four-point contact
QJ series
1) Single row and combined angular contact ball bearing
The more contact angle is, the larger axial load bearing capacity is,the smaller contact surface is,themuch
more convenient high speed rotary is.
Pretension is made on angular contact ball bearing to increase rididity and accuracy of bearing.
This bearing creates axial thrust load when being forced by radial load,thus it is configured(or combined)
face to face or back to back.
2) Double row angular contact ball bearing
Double row angular contact ball bearing can be subinitted radial and acial louding limit speed is quite high, it is non-separated type of bearing has high rigid can be submitted doubk direetion of axial load,the
bearing could apply with the four row cylindrical bearing together to limit the working roll to move in axial diretion the double row angular contact ball bearing could apply with other bearings as a position bearing.
3) Four point contact ball bearing
Standard structure is that its inner ring is equally divided in axial direction,which is applicable to axial load or combined load,among which acial load is major composition.
Single bearing can bear double row axial load and certain extent radial load.According to different direction of axial load,ring and sphere always contact at two points of linear
