In addition to radial loads, double row deep groove ball bearings can also withstand axial loads acting in two directions. These bearings are suitable for bearing arrangements where the load capacity of a single row deep groove ball bearing is insufficient.

Any misalignment between the inner and outer rings of a double row deep groove ball bearing will cause additional loads. Thereby increasing the load of the steel ball and the cage and shortening the service life of the bearing. Therefore, the allowable angular error is only 2 arc minutes. Any larger angular error will result in increased noise.

Cage

Double row deep groove ball bearings are fitted with two glass fibre reinforced nylon 66 cages. SKF suffix is TN9.

Attention

Bear pure axial load, generally not more than 0.5Co. Excessive axial loads may significantly reduce the bearing service life.
