Shaft seal bush ring

Rock Metal offers a wide selection of sealing materials in silicon carbide, carbon graphite, tungsten carbide, ceramic, rubber and stainless steel, etc. View our variety of sealing types equipped to handle the vast majority of sealing solutions and available for nearly all applications.

Silicon carbide (SIC) has the property of excellent resistant-corrosion, high mechanical strength, high thermal conductivity, good self-lubrication；working well in acid, weak alkali, organic solvents, etc. Used as seal faces, bearings and tubes in spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, pharmaceutical, auto industry and so on. When the sic faces are combined with graphite faces, the friction is the smallest and they can be made into mechanical seals which are able to work in highest working requirements.
