Schaeffler UK publishes plain bearings compendium

The 428-page catalogue guides selection.
Precision bearing manufacturer Schaeffler UK has published a 428-page catalogue on its range of plain bearings.

The catalogue contains information on ELGES radial, angular contact and axial spherical plain bearings, as well as rod ends, metal/polymer composite plain bearings (in the form of plain bushes), thrust washers/strips, and ELGOTEX plain bushes. The revised catalogue replaces three previous catalogues (238, 706 and ELGOTEX plain bearings).

The Technical Principles section has guidance on the selection of plain bearing for different applications. Design factors are considered, including load carrying capacity, rating life, friction, increases in temperature, internal and operating clearance, sealing, mounting and dismounting, and ISO tolerances.

The catalogue also contains updated chapters on Special Materials, including examples of non-standard materials that can be specified for spherical plain bearings such as glass fibre-reinforced plastic sliding layers. Other examples include E60, a new plain bearing material for maintenance-free film bearings. This metal/polymer composite comprises a bronze rib mesh that is filled with a dry lubricant made from PTFE with embedded chemically non-reactive additives. The mesh functions as both a carrier and a sliding layer.

The Special Designs chapter includes examples of custom-engineered plain bearings, such as plain bushes with slots, pivoting cradle bearings, ball cups, bush and pin systems, linear plain bearing units, flanged spherical bearings, prop shaft centering bearings, central joint bearings, and spherical plain bearings with bellows.

Throughout the catalogue are examples of X-life plain bearings. These are premium quality bearings that use higher performance materials, lower co-efficients of friction and reduced running-in wear when compared to conventional, standard plain bearings.
