Mechanical Carbon Products
Taking advantage of the self-lubrication and chemical and heat resistance features of carbon, our mechanical carbon grades are used for sliding parts in high temperature environments where metals cannot be used as well as for submersion in chemicals and in fields where lubricated parts cannot be used. Already, our carbon seals, rings, bearings and vanes are widely used and highly evaluated in a broad range of industries.
- Seal Rings
- Gland Rings
- Bearings
- Steam Joints
- Carbon Vanes
Seal Rings
Carbon sealing rings are used as the wear face of the most mechanical seals for the sealing of fluids in all industries. Seals are made in solid rings, split rings, and segmental rings for use in both liquid and dry running applications. Applications include Process pumps, Rotary steam joints, Seals for agitators and autoclaves, Chemical pumps, Cold and Warm water pumps, Corrosive liquid pumps.

Gland Rings
These rings are highly specialized products and used as shaft seals in fans, water and steam turbine installations, nuclear power stations and hydroelectric schemes. Gland rings are of two types Tenon types and Wedge types.

Bearings
This product offering includes Stocker Bearings, Axial Bearings, Bush Bearings, Clutch Bearings. Carbon is self-lubricating and has a low coefficient of friction at high and low temperatures. Its use as a bearing material is extensive when a conventional lubricant is not possible and also where the performance of other lubrication is poor. There are other properties which give it unique and distinctive advantages for bearings. Applications include Submersible pump motor, Vertical centrifugal pump, Aircraft fuel pump

Steam Joints
These joints connect a flow of liquid or vapour from a stationary supply piped to a rotating machine part, such as a roll, dryer or cylinder. Rotary pressure joints fitted with carbon rings are widely used in the paper industry. They also find application in the textile, plastics, rubber, petro chemical, food and other industries handling liquids and vapours up to temperatures of 350

Carbon Vanes
Carbon vanes are self-lubricating and are ideal for pumps, handling liquids such as petrol which has poor lubricating properties. Vanes can also operate in unlubricated compressors to deliver air or gas uncontaminated by lubricating oil or greases, in which carbon gives a fine polish to cylinder wall which reduces the wear rate of the vane after bedding almost negligible proportions. Carbon vanes are chemically inert and non-toxic and cannot contaminate the liquid or gas being handled. They can safely be used in food-processing equipment and in other fields where purity is essential. Carbon vanes are totally unaffected by water (pure or salt), most acids, alkalis or oil solvents such as petrol or paraffin. In these conditions, the liquid can reduce friction and wear by providing lubrication between vane and rotor slots and vane top and cylinder wall.
One of the most important requirements for vane materials is high mechanical strength. Carbon vanes meet this requirement. Their strength is indicated by the pressure regularly handled, which ranges from 3.2 kgf/cm2 down to high vacuum conditions, with peripheral speeds up to 12.7 m/sec.
