The bearing is fixed and reducing load coefficient of friction parts of the mechanical transmission in the process of. Can also be said that when the other parts on the shaft between the relative motion to reduce power transmission in the process of friction coefficient and adhere to the fixed position of the parts for the central axis.

Bearing composition

Is one of the bearing parts of rolling bearing parts, but does not include all attachments.

Bearing ring: ring with one or several parts of the heart of the rolling bearing raceway.

Bearing washers: ring with one or several parts of the thrust bearing raceway.

Flat ring: a separable substantially flat washer, with the inner and outer part as centripetal cylindrical roller bearing outer ring or inner ring of a flange.

Oblique ring (separable a separable "L-shaped section of the circle, the outer part as a centripetal cylindrical roller bearing inner ring of a wall.

Check ring with two or more columns roller roller bearings in a separable ring for isolation of two rows of roller and guide roller.

Stop ring: a ring with constant cross section, installed in the ring ditch, the rolling bearing in the shell or the shaft axial positioning.

Lock ring: single ring with constant cross section, installed in the ring ditch as collar or the roller frame to keep in bearing.

The spacer ring: ring parts for between the two bearing rings, or bearing washer, or two and a half between the bearing ring or two and a half between the bearing washer to make it adhere to the provisions of the axial distance.

Sealing ring: composed of one or several parts of the ring cover, fixed on a ring or a washer bearing and other ring or gasket contact or the formation of narrow clearance of the labyrinth to prevent leakage of lubricant and external invasion.
