Excavator Cylinder Step Seal

Other seals and step seals differ in the following ways:

1. The seal of the piston rod of a hydraulic cylinder is better suited by a step seal.

Piston step seals and rod piston step seals are two types of step seals that have a single action.

3. The benefits of step seals include minimal friction, no crawling, a modest starting force, strong pressure resistance, and a straightforward groove shape, among others.

4. The material consists of an O-ring and a sealing ring (nitrile rubber or viton).
