PISTON RINGS

Description

Piston rings play the role of controlling lubricating oil, and because they are used in a high-speed motion part, they are critical functional parts demanding high precision and high durability.
as KETSUMI piston rings improve engine fuel efficiencies, a critical challenge is to make engines lighter, with reduced mechanical losses. To reduce the friction losses around pistons, where approximately 40 to 50% of total engine friction losses occur, there is an increase in “thin Piston Rings for compactness” and “low tension Piston Rings”. In addition to thin, low tension Piston Rings, we offer KETSUMI unique new technology.
