HZ-RFC High strength cloth-reinforced phenolic bearing

Material Introduction

PFC-1 material is a high-strength load-bearing material that uses thermosetting linear phenolic resin as the substrate and high-quality cotton fiber fabric as the reinforcement material and is heat cured under certain temperatures and pressure. It has ha igh load-bearing capacity, good temperature resistance, wear resistance, and good dimensional stability. Suitable for hydraulic cylinder guide rings, support rings, construction machinery, swing bridge support bushings for construction vehicles, thrust washers, hydraulic machinery column guides, etc.

Typical applications

01 / hydraulic cylinder guide ring, support ring
02 / hydraulic machinery, forging machine tool column guide sleeve
03 / construction machinery, vehicle swing axle bracket bushing

Material Introduction

PFC-2 material is a high-strength composite material formed by thermosetting at a certain temperature and pressure using soluble phenolic resin containing uniformly dispersed graphite and high-quality cotton fiber fabric. It has high mechanical strength, excellent friction and wear performance, good temperature resistance, and can withstand strong vibrations, impact loads, and mild rotational loads under semi-static conditions. It can work in a low oil or oil-free state and is suitable for engineering machinery, engineering vehicle swing bridge support bushings, forging press bed column guides, spherical bearings, etc.
