Double Row Angular Contact

Angular Contact Bearings are double-row angular contact ball bearings. Each of the two rows has a 30° contact angle. Polyamide cages offer high-impact strength, abrasion- and wear-resistance, and energy and shock absorption.These type of bearings are made in two contact angle levels as shown in Table. They are selected according to sustained axial and moment load.

Cages are made of pressed steel. Some sizes of Double-row Angular Contact Ball Bearing are available with contact seals (2NS) or shields (ZZ). A double row angular contact ball bearings correspond in design to two single row angular contact ball bearings arranged back-to-back, but take up less axial space. They can accommodate radial loads as well as axial loads in both directions.

Double row angular contact ball bearing have two rows of balls arranged back-to-back. The lines of action of the load at the contact between balls and raceways (load lines) diverge at the bearing axis and form an angle of 30° to the radial plane. In essence, they work similarly to having a matched pair of Single Row Angular Contact ball bearings either face-to-face or back-to-back.
