Rider Rings

For reciprocating compressors

  • Selection from a comprehensive range of tribological materials
  • No pressure applied to the rider ring by relief grooves
  • Conversion of cylinder from lubricated to non-lubricated operation

In reciprocating compressors, rider rings guide the piston in the cylinder bore. HOERBIGER manufactures them from materials that are specifically developed for the respective application.

The interaction between the ring design and tribological properties yields optimum results. The extensive range of materials available at HOERBIGER makes it easy to select the right product for any application. In conjunction with a construction that is designed with the particular use in mind, this results in a long service life, even with wet and dry gases, at all molar weights of gases, and with contaminated or corrosive gases.

HOERBIGER rider rings are suitable for use in lubricated and non-lubricated reciprocating compressors.
