PFC-20 high strength fabrice resin guide ring is made of solute phenolic resin containing homogenously dispersed graphite and high-quality cotton fiber and finally finished with heat solidifying process under certain pressure and temperature. This material is featured in its high mechanical strength, excellent abrasion resistance and excellent temperature resistance, ability to sustain strong vibration under semi-static state, ability to sustain impact loads and slight torque loads. It can work under conditions where oil is little or even with no oil at all. It is applied to the production of bushings for the pillars of hydraulic machines as well as guiding sleeves for the vertical pillars of forging presses and spherical bearings.
