Sealing
Rider rings are mainly used to correct the axial run out of piston rings.
These rings, mounted in the upper or lower part of a piston, are necessary to increase the piston's compression efficiency. Their materials are selected according to the service condition.
Also, rider tings with metal are sometimes used to prevent back pressure.
