ANGULAR CONTACT BALL BRG DOUBLE-ROW ZZ CN P0 20X52X22.2MM BTC

Double-row angular contact ball bearings have two rows of balls arranged back to back. 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. The difference is that double-row angular contact ball bearings can take a bi directional axial load in one bearing where it takes a matched pair otherwise. This means the bearings are particularly suitable for accommodating simultaneously acting radial load and axial load in both directions. Fitted with two metal dust shields to prevent the ingress of dirt and foreign matter.
