CONSTRUCTION OF BEARING UNITS

ASAHI Bearing Units consist of a double sealed single row deep groove ball bearing and any one of cast iron, synthetic rubber or pressed steel housings of various configurations. The self-contained bearing with spherical ground outside diameter is assembled into a corresponding spherical seat of the housing providing self- alignment of the bearing in the housing at mounting.

Set-screw locking is most popular method of mounting to the shaft. Adapter sleeve and eccentric locking collar are also available. For services under more severe operating conditions, Bearing Units with Cast Iron Covers and Pressed Steel Covers are available as standard types.

FEATURES:

• Rational self-alignment: The outside diameter of the self-contained bearing is ground spherical to match corresponding spherical inside diameter of the housing providing self-alignment between these two members, which compensates for misalignments of the units resulting from errors in mounting and distortion of the foundation.
• Larger load carrying capacity: Being the same as 6200 and 6300 series single row deep groove radial ball bearings in internal construction of the self-contained bearing, Bear ing Units can sustain radial loads and substantial thrust loads as well. Quiet Operation is also assured.
• Longer service life: Bearing Units are often used in severe operating conditions where they are exposed to dirts, moisture or high temperature, and in such applications, the grease inside the self-contained bearing deteriorates in a short period of time. It is required, therefore to relubricate the units at suitable intervals so as to replace deteriorated grease with fresh grease. ASAHI Bearing Units with cast iron and rubber housings are all relubricatable type equipped with grease fittings to secure full performance and longer service life of the units under any Operating condition
• Solid housing: The cast iron housing is of solid one-piece con struction to provide maximum rigidity against deformation at mounting and wear resistance for any operating condition.
• Easy installation: The self-contained bearing is prelubricated with an adequate quantity of high quality grease. Bearing Units can be mounted on the shaft for immediate operation. The units are, therefore, free from ingress of harmful contaminants into the bearing chamber during mounting pro cedures.
• Easy positioning for mounting: Two dowel bases provided on the housing of Pillow Block, Square Flange and Two-Bolt Flange Units serve for easy and accurate positioning of the units when mounting them on the structure.
