M-4 Guide ring

Introduction

M-4 Guide ring is made from polyester fabric and phenolic resin, with MoS2 particles lubricant. It is also called polyester wear ring, or polyester guide ring.

M-4 Guide ring can be used in the gas spring applications, it's function is to guide the piston and piston rod, absorb transverse forces, prevent metal-to-metal contact, and optimize the performance of the sealing system, plays a very important role in hydraulic and pneumatic sealing system.

Material Benefits
