Brass Cage Spherical Roller Bearing

Spherical roller bearings have two rows of rollers, a common with spherical outer ring raceway and inner ring raceway in the bearing axis into an angle tilt. The centre point of the spheres in the raceway of the outer ring is at the axis of the bearing. The bearing, therefore, is self-aligning and insensitive to shaft misalignment relative to the housing, which can, for example, be caused by deflection of the shaft. Spherical roller bearings are designed to carry heavy radial loads, as well as heavy axial loads in both directions.

Mounting forms

Angular contact ball bearing fast and easy automatic selection book can provide selection, angular contact ball bearing mounting forms, there are back-to-back, face-to-face and tandem arrangement of three. Back to back (two bearings of the wide end face relative) installation, bearing contact angle line along the direction of the rotary axis diffusion, can increase its radial and axial support angle rigidity, resistance to deformation capacity of the largest; face to face (two bearings of the narrow end face relative) installation, bearing contact angle line towards the rotary axis direction convergence, its support angle rigidity is smaller. As the inner ring of the bearing extends out of the outer ring, when the outer ring of the two bearings are pressed together, the original clearance of the outer ring is eliminated, which can increase the preload of the bearing; Tandem arrangement (the wide end face of the two bearings in one direction) when installed, the contact angle line of the bearing in the same direction and parallel, can make the two bearings share the same direction of the working load. However, when using this mounting form, in order to ensure the axial stability of the installation, two pairs of bearings in tandem arrangement must be installed at the opposite ends of the shaft.
