2. Construction

The TANN mounted bearing unit is a bearing unit that combines the spherical outside surface ball bearing, seal, and a housing of high-grade cast iron or pressed steel. It features a variety of structure patterns and is suitable for application under tough conditions.
The outer surfaces of the bearing and the internal surface of the housing are spherical, so that the unit is self-aligning. Set-screw locking is the most popular method of mounting to the shaft. Adapter sleeve and eccentric locking collar are also available. For service under more severe operating conditions, Bearing unit with cast iron covers and pressed steel covers and or in plastic available as standard types.
The covers are constructed i such a way as to guarantee even eventual substitution of rubber seals with common selt rings. There are also closed covers used in application where the shaft does not pass.
The outside diameter of the self-contained bearing's ground spherical to match corresponding spherical inside diameter of the housing provide self-alignment between these two parts, which compensates for misalignments of the units resulting from errors in mounting and distortion of the foundation.
