There is no doubt piston rings from SPR offer the finest quality available in the world today. For a piston ring supplier who can offer total quality, reliability and service, turn to SPR.

Of course, the major engine differentiation is between 2-stroke and 4-stroke cycle specification but cylinder bore and engine RPM are also very important influences on the pattern of the piston ring pack.

Large slow speed two-stroke diesel engines used to contain 5 or 6 compression rings, all of the same design. No scraper rings are necessary as lubrication oil is injected into the cylinder bore and consumed within the engine. More recently only 4 rings have been used to help reduce engine friction. The top ring now often differs from the lower rings both in terms of its geometry as well as the materials used for its construction to allow it to better withstand ever-harshening conditions within the engine.
