M-3 Guide ring

Introduction

M-3 Guide ring is made from polyester fabric and polyester resin, with PTFE particles lubricant. It is also called polyester wear ring, or polyester guide ring.

M-3 Guide ring can bear high surface pressure, can be used as piston guide ring and rod 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

Very low humidity absorption
Improved Sliding behavior
Good Chemical resistance
High load bearing capacity
Improved self-lubricating property
High flexibility, easy installation
