Sliding bearings for the working conditions with the hydrodynamic lubrication, suitable for static and dynamic load.
The sliding material is deposited by the casting on the base steel. It has got a universal structure, it is characterised by good sliding characteristics also under the conditions of boundary friction. Normally it is being used with galvanically spread superficial layer of PbSn. The bearings with the lining BS 3332 are not being galvanised. A journal in sliding bedding does not require superficial friction. For the high loaded sliding bedding, the sliding material CuPb22Sn with higher dynamic load is used. Because of its good sliding characteristics, they are applied as the main crank bearings in combustion engines, as the bearings of tool machines etc.
The dimensions of bearings, which are produced by this method :
- minimal diameter : 20 mm
- maximal diameter : 500 mm
- maximal width : 400 mm
