STASSKOL offers an extensive range of one-piece and multipiece piston and rider rings, with or without expansion springs, as well as pressure relief grooves.
There are single acting and double acting pressure relieved piston rings in one-piece an multi-piece designs with rectangular or angular section. Twin rings are also able to be supplied.
Rider rings of a one-piece, multi-piece or solid can be supplied. The design of the reciprocating compressor and working conditions determine the design. Beside the temperatures the unit loading is the most important design criterion for ring dimensions.
