Tungsten carbide is an inorganic chemical compound which contains
numbers of tungsten and carbon atoms. Tungsten carbide, also known
as “cemented carbide”, “hard alloy” or “hardmetal”, is a kind of
metallurgic material which contains tungsten carbide powder
(chemical formula: WC) and other binder (cobalt, nickel. etc.).
Tungsten carbide bearing bush shows high hardness and transverse
rupture strength, and it has superior performance on resisting
abrasion and corrosion, which enable it to be widely used in many
industries.
The tungsten carbide bearing bush sleeve will be used mainly for
rotating support, aligning, anti-thrust and seal of the axle of
motor, centrifuge, protector and separator of the submerged
electric pump in the adverse working conditions of high speed
rotating, sand lash abrasion and gas corrosion in the oil field,
such as slide bearing sleeve, motor axle sleeve and seal axle
sleeve.
Cemented carbide sleeve adopts raw and auxiliary materials such as
primary saturated tungsten carbide, high-purity ultra-fine cobalt
powder, precise carbon blending, tilt ball milling, vacuum stirring
drying, precision pressing, digital degreasing sintering and
pressure sintering personalized post-processing and other advanced
powder metallurgy processes. Hard alloy sleeve is widely used in
special pump industry, with long service life and reliable quality.
Bearing bush sleeves are working in an abrasive environment due to
rotation, friction, etc. and the particles involved in the media.
Tungsten carbide bushing sleeve with wear and corrosion resistance
and a high fracture toughness for demanding axial thrust, and could
meet API standard disaster bushing requirement.
