DOUBLE-ROW ANGULAR CONTACT

Double-Row Angular Contact Ball Bearings

Our differentiated strong line. Two rows of balls in a back-to-back arrangement handle combined radial and axial loads in both directions — ideal for applications where a single deep-groove bearing isn't enough.

Typical applications: Gearboxes, pumps, compressors, machine tool spindles, automotive wheel hubs, lifting equipment.
