Product Description

   We can also supply thrust washer used on the pumps.Standard or non-standard , Tailor-made parts according to the customers' drawings or samples. 

    Thrust plates in a variety of styles, flat plate, tapered land, compound tapered land, pressure pocket, and step. Solid or split designs are available in diameters ranging from 1.5 to 25 inches. Thrust plates sizes are determined by the requirements of the application. Thrust plate designs can also be integral with the journal bearing shell. Orion offers a complete line of pivoted shoe journal bearings with flat plate or tapered land thrust face designs.

Silicon Carbide (SiC) is one of the most popular high performance tribo-materials, which has been commercially available for more than twenty-five years. Its features include:

· Excellent abrasion and wear resistance
· Excellent corrosion resistance
· Low coefficient of friction
· Low coefficient of thermal expansion
· High thermal conductivity
· Hardness greater than Tungsten Carbide

Different grades of Silicon Carbide are available as following:
· Reaction Bonded Silicon Carbide (RB SiC) - a very economical material which gives excellent wear characteristics, as well as good chemical resistance.
· Sintered Silicon Carbide (SSiC) - the absence of free silicon makes it most resistant to chemically-aggressive fluids, and ideal for high temperature applications.
· Graphite-Loaded Silicon Carbide - this is a composite of silicon carbide and free graphite. Graphite is added to RB SiC (RB SiC + C) or SSiC (SSiC + C), to improve tribological behavior by enhanced lubricity.
