These bushes are assigned for working conditions with hydrodynamic and limited lubrication for transfer of rotary and translation movemments. They allove withstand the static and dynamic radial forces. They are made from bimetalic strips with various sliding layers in the Shape of the wrapped bushes with the gapping on the join. The bushes in the which fast joins the contact surfaces. The sliding material B10, B22, B30 is sintered on the found steel in the form of the powder and is compacted by the rolling. It has the homogeneous structure and good slide properties in the conditions of boundary friction. The sliding material A20 is plated on the found steel.
