Thrust washers are manufactured from Wieland strip, tubes, and rods. In particular, washers punched out of strip material are very economical in large quantities. You can order thrust washers made from strip as well as tubes and rods in almost every dimension and material. The design can be customized.

With over 150 active alloys we offer you a great range of materials - find the right solutions for your application.



Materials

Dimension range:

  • With plain running surface up to 155 mm diameter
  • With lubrication indents up to 110 mm diameter
  • In standard thicknesses of 1.0 / 1.5 / 2.0 / 2.5 and 3.0 mm
  • Other sizes upon request

 Further designs:

  • With grooves
  • With safety dogs
  • As a segment
  • Curved / Convex

New piston designs have become necessary due to legislation for pollutant emission of diesel engines. These design changes result in rising temperatures in the combustion chamber of the engine, with hot tensile strength and hot hardness of the bushings becoming increasingly important.

Bushings made of Wieland-SB8 and Wieland-SC5 are particularly suitable for the reinforcement of the piston eye.

Bushings in Wieland-SB8 and Wieland-SC5:

  • are particularly suitable for aluminium pistons
  • are wrought alloys (important: no casting) which are hot and cold worked
  • have excellent hot tensile strength
  • have outstanding oil corrosion resistance
  • have dynamic load resistance up to 170 MPa, with Wieland-SC5 even more than 170 MPa.

The very high pressures in axial piston pumps are a challenge to the material and the precision of the parts. Therefore high-strength materials are increasingly used in the following applications.


In the field of special parts, we specialize in the manufacture of assemblies made of different material combinations as well as in the manufacture of other milled and turned parts, screws, nuts, thread inserts, etc. These products are made of different materials such as copper and aluminum alloys as well as partly steel and cast steel.

Types

  • Assemblies made of different material combinations
  • Milled and turned parts
  • Hot-stamped parts
  • Screws
  • Nuts
