Piston rings and rider bands are used in horizontal, vertical and v-shaped cylinders.
STASSKOL manufactures a wide range of one-piece or multipiece piston rings and rider bands with and without expansion springs as well as pressure-relief grooves. The axial and radial dimensions and the ring gaps are decided for long-life cycle of the piston and rider rings. The basis for the exact calculation is mean piston temperature as well as the coefficient of expansion of used materials.
