Single-row Angular Contact Ball Bearing Inner Diameter: 60-750 mm

Duplex Angular Contact Ball Bearing Inner Diameter : 45-380 -mm
Double-row Angular Contact Ball Bearing Inner diameter: 45-300 mm
Four-point Contact Ball Bearing Inner diameter: 30-560 mm
Two-way Thrust Angular Contact Ball Bearing Inner Diameter: 100-170 -mm

Angular contact ball bearings are suitable for high speed and high precision rotation, and can withstand synthetic loads.

Single-row and Combined Angular Contact Ball Bearing

The standard contact angle is 15 °, 25, and 40 °, with respect auxiliary code— "C", "AC" and "B".

The bigger the contact angle is, the greater the capacity of axial load is; the smaller the contact surface is , the more conducive it is to the high-speed rotation.

Angular contact ball bearings are mostly preloaded to improve their stiffness and rotation accuracy.

The axial thrust load will occur when these bearings are bearing radial load, so two bearings should be assembled face to face or back to back(or in combination).

Double-row Angular Contact Ball Bearing

Only the inner ring and the outer ring of two single row angular contact bearings in a back-to-back structure are used.

Four-point Contact Ball Bearing

The standard structure requires the axial in the Inner ring has an contact angle of 35 °, suit for purely axial load or synthetic load with larger axial load .

A single bearing can bear two-way axial load and radial load in a certain degree. The ring can always contact balls at 2 points in any side of the contact line according to the direction of the axial load.

The conditions for using four-point contact ball bearings, such as the bearing load etc., should be fully analyzed. For more information, please contact WGYS.
