Bearing basic technical knowledge

Bearing joints: the sliding contact surface of the spherical, mainly applicable to swing movement, tilting movement and rotation of spherical plain bearings.

Bearings: a set of bearing two or more simultaneously by said bearing structure combination of rolling bearings. Such as needle roller and thrust cylindrical roller bearings, needle roller and thrust ball bearings, needle roller and angular contact ball bearings.

Other Bearings: In addition to the above other than the structure of the rolling bearing.

2, the bearing parts

Bearing parts: one consisting of the parts bearing, but does not include all the accessories.

Bearing rings: one or several raceway bearing to the heart of the annular parts.

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

Flat ring: a detachable substantially flat washer, use it as an inner or outer part of the radial cylindrical roller bearing outer or inner ring of a wall.

Thrust collar (detachable): a separable with "L" shaped cross-section ring, with the outer part of a radial cylindrical roller bearing inner ring of a wall.

In the ring: having two or more rows of rollers of a roller bearing inner ring separable used to isolate two rollers and guide rollers.

Snap ring: single port having a constant cross-section ring, mounted in a ring ditch, a roller bearing in the housing or shaft axial position.

Lock ring: single port with constant cross-section ring, mounted as a ring in a ring ditch rollers or cage will remain in the bearing.

Spacer: the annular parts, for the two bearing rings or bearing washer, or between the two halves or between the bearing rings between the two halves of the bearing washer, so that they are maintained between the axial distance required.

Seals: formed by one or several parts of the ring cap fixed to the bearing and a ferrule or the gasket ring or gasket in contact with another or to form a narrow gap labyrinth, prevent oil leakage and foreign matter.

Cover: is a ring cover, usually a thin metal plate stamping, a ring fixed to the bearing or washer and extending towards the other ring or gasket, cover bearing internal space, but not with another ring or gasket contacts
