JOINT-TYPE BEARINGS

Joint-type bearings - are sliding bearings. They include inner and outer rings and do not have rolling elements. Inner ring has spherical outer surface, outer ring has spherical inner surface. Joint-type bearings are designed to bear radial and combined loads in sliding and fixed connections.

These bearings may be produced with one fractures of outer ring (IllCn type) or with two fractures of outer ring (IHCJI type). Bearings with movable connection operate with mutual displacement of one ring towards the other in vibrating MIDI mode generally with angle up to 45°. Herewith angle of distortion up to 4. ..22° is allowable depending on construction.

Bearings with fixed connection operate with frequent singular displacement of one ring towards the other and are designed generally to compensate axis misalignment of shaft and housing. Bearings for movable connections are produced with bores and grooves for lubrication supply provided both in outer and inner rings (LLIC...K type), as well as in inner ring only (UIC type). Bearings for fixed connections are produced without any bores or grooves for lubrication supply (III type).
