Tungsten Carbide Mechanical Seal Ring / Flat Tungsten Ring Dimensions Customized
Production Description
1.Tungsten carbide mold is in high precision,the tolerance can
according yours.
2.For the shape,size,material etc. are made by customers' needs and
requirements.
3. It has many advantages such as Wear resistant, Heat resistant
and Corrosion resista and so on.
Product characters of carbide roller ring
Virgin raw material, fine processing, high precision, diamond polishing, wear resistance and long service life.
Outer surface is as sintered, inner surface is crowned and diamond polished to 10 micro and no lines and steps to be seen. Make sure no scratches when wires passing through the guides.
Carbide wire guide is made of tungsten carbide for its extremely hard and wear-resistant features, with sophisticated equipment for precision grinding and polishing, coupled with advanced production and processing technology, the inner and the outer diameter of the hole and tolerance R at less than 0.01mm, the surface roughness over the trough reached Ra 0.025 and above, it requires high hardness, smooth surface in use to reduce injury and other enameled wire
