Radial bearing structure

- Sep 23, 2019-

Radial plain bearings are available in split, integral, flanged and self-aligning versions. The bearing cap of the split bearing can be opened to facilitate the loading of the journal, and the bearing bush can be easily adjusted after the bearing is worn. The integral bearing is simple in construction, but the journal must be loaded from one end and the gap cannot be adjusted after wear. The mounting surface of the flanged bearing is perpendicular to the bearing centerline. Self-aligning bearings automatically adjust the axis to accommodate the deflection of the shaft.

 

The diameter of the inner bore of a radial plain bearing is called the bearing diameter. The axial dimension of the bearing pad is called the bearing width. The ratio of the bearing width to the bearing diameter is called the aspect ratio, which is generally 0.4 to 1.5, and 0.25 is also taken to reduce the axial dimension (as in an internal combustion engine). The aspect ratio has a large impact on bearing performance.
