Bibliography

Describes quality control techniques and inspection of the geometrical and material quality characteristics of various types of plain bearing.

This International Standard specifies quality control techniques and inspection of the geometrical and material quality characteristics of the following types of plain bearings:

  • thin-walled half-bearings with or without flange, as specified in ISO3548;

  • metallic thick-walled half-bearings (with and without flange) that are manufactured as halves but that are necessarily interchangeable and have the ratio s3 : Do>0,11;

  • wrapped bushes, as specified in ISO3547;

  • unsplit metallic bushes (with and without flange) made from solid and multilayer materials and with outside diameters up to 230mm;

  • solid polymer bushes (with and without flange) with inside diameters up to 200mm;

  • ring-type thrust washers and pressed bimetallic half-thrust washers, as specified in ISO6525 and ISO6526, respectively;

  • bushes made from sintered material, as specified in ISO2795.
