Self Aligning Ball Bearings

SBB have two rows of balls, the outer ring has a common concave spherical raceway, and the center of curvature is the same as the center of the bearing. Even if the inner ring, the steel ball and the cage are slightly inclined relative to the outer ring, they can rotate. Therefore, the bearing is self-aligning and will not be affected by the misalignment of the shaft relative to the bearing housing. It is mainly used to bear radial load, but can also bear a small amount of axial load, and generally cannot bear pure axial load. It is especially suitable for bearing applications where considerable shaft deflection or misalignment may occur. For example, precision instruments, low-noise motors, transmission shafts of automobiles, motorcycles, woodworking machinery, textile machinery, mining machinery, electromechanical equipments, plastic machinery, office equipments, medical equipments, fitness and sports equipments, and general machinery, etc. are the most widely used type of bearings in the machinery industry.

Tolerance

The tolerance class of ZWZ standard SBB meets the requirements in GB/T 307.1.

Radial Clearance

ZWZ standard SBB have 2, standard (N), 3, 4 and 5 class internal clearances, all of which are in line with GB/T 4604.1. The tapered hole SBBuse 3 sets of clearance as the standard. The value applies to unmounted and unloaded bearings. Bearings with internal clearance greater than or less than the standard value can also be produced according to user requirements.

Cage

The cage generally adopts stamped cage, solid brass cage and nylon cage. The materials are steel, brass and synthetic resin, etc.

When the outer diameter of the bearing D≤200mm, use the stamped steel plate (belt) cage, without marks of cage suffix.

When the outer diameter of the bearing D>200mm, use the solid brass cage, without marks of cage suffix.

The operating temperature of nylon cage bearings can reach up to +120℃. For bearings that need to operate continuously under high temperature or harsh conditions, a solid brass cage can be considered. For bearings with non-standard cages, please contact ZWZ in advance.
