Description
The insert meters hydraulic oil and is part of the hydraulic cylinder piston assembly.
Features
The insert used in a hydraulic cylinder piston meters hydraulic oil and minimizes high-speed movement of the piston and rod assembly, preventing cylinder damage. As pressure in the cylinder chamber increases, pressure can be bled off through the insert to slow piston movement as the piston approaches the cylinder head or the cylinder end.
Recommended Use:
This type of hydraulic cylinder insert is typically used where the hydraulic cylinder is subjected to constant heavy loads, such as the tilt cylinders on dozers with large tracks.
