Z Cut Wear Ring Seal

The guide wear ring has precise guiding support for the moving piston and piston rod and absorbs the radial force generated at any time. Ensuring that the seal is not broken by radial forces has been achieved for the purpose of extending the life of the hydraulic cylinder.

Max pressure: ≤15N/mm²
Temp range: -50 ~+200℃
Max Speed: ≤15m/s

Description-Wear ring seal

Wear ring seal provides guidance and support for the piston and piston rod of the hydraulic cylinder. As well as absorbing lateral loads. At the same time, it can prevent metal contact between the moving parts of the cylinder and optimize the performance of the sealing system.

The washer, gasket are the mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

Gaskets for specific applications, such as high-pressure steam systems, may contain asbestos. However, due to the health hazards associated with asbestos exposure, when practical, we are using non-asbestos gasket materials.

● Good wear resistance
● Avoid contact between metals
● Can suppress mechanical vibration
● Due to the centering action of the wear ring, a large radial clearance is allowed
● The groove is simple and easy to install
● Low maintenance costs are based on the above advantages, so it is widely used
