Radial plain bearing / thin-walled / bronze / self-lubricated

Thin-walled split radial plain bearings are applied for two-stroke crosshead and four-stroke trunk piston internal combustion engines and for other piston-type machines. They are generally used as main bearings, conrod bearings and crosshead bearings, and as bearings for camshafts and control shafts.

The ZOLLERN plain bearing shells are:

designed for internal combustion engines and other piston-type machines, but also proven in other areas of general industrial machines, e.g. gearboxes and roll stands
with a ratio of wall thickness to diameter less than 0.06
bimetal plain bearings in materials consisting of steel/white metal or steel/aluminium, trimetal plain bearings made of steel/bronze or steel/aluminium with an additional lining
with steel supporting shells and bearing metal coatings of between 0.5 and 3 mm and linings of between 0.01 and 0.04 mm
type of material selected to meet the requirements of the stress loading profile
made in exchangeable halves. When arbitrarily assembled, the pair of bearing shells always fits in such a way that, when installed, the seat complies with the specified prestress level
if required, compensation for housing distortion by adapted wall thickness progression to support the optimum bearing function, so that the inner diameter complies with a geometric shape which favours the formation of a uniform lubricating film
tested with special crush height measuring machines, which we produce also for our customers. The crush height is the characteristic required to achieve the necessary prestress in installed condition
