Production Description:

SKF 21304CC Low Vibration And High Performance Spherical Roller Bearing 21304 With Fast Delivery Time

Spherical roller bearings Spherical bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.

It has two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. They are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
