M-2 Guide ring

Introduction

M-2 Guide ring is made from cotton fabric and phenolic resin, with graphite particles lubricant. It is also called phenolic wear ring, or graphite wear ring.

M-2 Guide ring can bear high surface pressure, often used as piston guide ring, 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

Good wear resistance
Good dimension stability
Extended service life
Self-lubricating by graphite
Low maintenance cost
Wide range of dimensions
