Angular contact ball bearing type:
Single row angular contact ball bearing: only carry a direction of the axial load, when in bear radial load, can cause additional axial force must be applied to the corresponding reverse load, therefore, the bearings are generally used in pairs.
Double row angular contact ball bearing: At the same time can bear radial and axial load joint load, limit shaft on both sides of the axial displacement.
Angular contact ball bearing main technical indicators:
(1) Bearing precision index: More than GB / 307.1-94 P4 level accuracy
(2) High-speed performance index: 1.3~1.8x 106 /min
(3)Service life:more than 1500h
Feature:
1) Load capacities are higher than deep groove ball bearings of same dimensions
2) Used for bearing radial-axial combined loads or pure thrust loads
3) Low operating friction and high limiting speed
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
Tolerance & Precision.
Accuracy from low to high is expressed as P0 ( general ), P6 (P6X), P5, P4, P2
