Our liners are centrifugally cast using premium-grade cast iron, ranging from 150 mm to 500 mm in diameter, and are compatible with a wide range of engine models.
To ensure superior durability and abrasion resistance, our liners are made from alloyed lamellar graphite cast iron—engineered to perform under the toughest conditions. Most liners are pre-honed for easy installation and optimal oil film formation. Upon request, additional treatments such as annealing, chromium or nickel plating, and roller burnishing can be arranged to suit specific operational requirements.
All cylinder liners supplied by JRS meet stringent industry standards and are certified by major classification societies, assuring quality, reliability, and long service life.
