Поршневое кольцо, внутренний диаметр 188 мм Caterpillar 7Y0976

A Piston Ring is a sealing component located within the adjuster's piston. The ring sits snugly within a groove on the piston's outer surface, creating a tight seal against the cylinder wall. This seal prevents hydraulic fluid from leaking past the piston, ensuring efficient transfer of pressure to the track tensioner.Attributes:• Minimizes friction between the piston and cylinder, protecting both components from excessive wear and tear• Helps to dampen the vibrations caused by the movementsApplications:A Piston Ring is used to maintain pressure within the adjuster's cylinder. As hydraulic fluid enters the cylinder, it pushes against the piston. The ring ensures this pressure remains focused on the piston and doesn't leak past, allowing for the effective extension of the track tensioner and subsequent tightening of the tracks.
