Bushings

One-piece radial plain bearings for the piston pins of four-stroke trunk piston internal combustion engines and crossheads, camshafts and control shafts, intermediate bearings, rocker arms and items of ancillary equipment such as pumps – also as combined radial/ thrust bearings.

The ZOLLERN bushings are:

  • for universal applications in engine and machine manufacturing, in thin- or thick-walled designs
  • available in various combinations of materials and dimensions from 50 to 800 mm
  • made of steel/lead-bronze or steel/white metal by the compound centrifugal casting method
  • made of steel/lead-bronze or steel/aluminium bimetal strip with welded joint, with electroplated lining as an option
  • optionally available with galvanised coating
  • with precisely turned or ground outer diameter (between centres or centreless)
  • with special external shape for piston pin bushings
  • with specially shaped grooves for oscillating movement
  • with precise concentricity of outer and inner diameters
  • with defined eccentricity of outer and inner diameters
  • with cylindrical bore or multi-lobe sliding profile
  • with special supporting cradle for crosshead bushings without lift
