Cylindrical bore type for 0.787 in. / 20 mm. shaft diametr, outer ring surface is cylindrical.
Made of hardened carbon chromium bearing steel, most widely used material for bearing rings and rolling elements.
Principal dimensions is 0.787х2.047х0.874 in. equal to 20х52х22.2 mm.
Capped by non-contact steel shields on both sides, filled with the appropriate amount of high quality grease under clean conditions. Typically should not be washed or relubricated, lubricated for the life of the bearing.
Contact angle is 30 °
Two-piont (normal) contact type.
Sheet metal cage.
Metric series product.

Double row angular contact ball bearings suitable for radial and axial loads acting simultaneously, where the axial load and tilting moments acts in both direction. In their design and operation correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement (O-arrangement), while requiring less axial space. They can operate at high speeds and, depending on the variant, even very high speeds. Require less axial space than equivalent pair of single row angular contact ball bearings, suitable where a stiff bearing arrangement is required.
