3313-DA-MA Double-Row Angular Contact Ball Bearing

Double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide or sheet steel cages. The bearings are available in open and sealed designs. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Sealed bearings are maintenance-free and therefore allow particularly economical bearing arrangements.

Bearings of series 33..-DA have a split inner ring. Due to the contact angle of α = 45°, they can support very high axial forces in both directions.The inner ring halves are matched to the particular bearing and must not be interchanged with those of other bearings of the same size.

Open bearings are suitable, depending on their outside diameter, for different operating temperature ranges. Bearings are available by agreement for temperatures up to +200 °C
