About Us
We are a group engaged in various fields of engineering services and have a background supported by 35 years of experience in carrying out repairs to worn out or damaged INDUSTRIAL & MARINE equipments.
Guided with the experience and capability of Mr.Girish Singh, we have achieved high standards in the production of large white metal and babbitt lined bearings. We have the ability to repair/reline worn out bearings as well as manufacture new bearings from prime grades of ferrous and non-ferrous outer castings. Our machining and testing facilities compare to the best in the industry. Remetalling equipment has been developed in-house for centrifugal lining of bearings upto 1 metre diameter.
We have the capacity to produce high quality bearings for use in equipment/industries such as: Diesel Power Generators, Steam Turbines, Steel Plants, Cement, Marine Propulsion, Stern Tube Bushes, Petrochem, Steel Cold Rolling Mills, Roll Neck Bearings, Sugar Mills, Power Plants, Hydroelectric Power Plants, and Large Electric Motors..
White metal compositions of most types are regularly stocked by us and we provide certified test reports that establish the true composition of the babbitts used by us.

Process: Centrifugal Lining
We hope you will find this information useful in understanding the centrifugal casting process, the superior quality it provides and the ways we can help you to reline old WHITE METAL bearings unto 80 inches dia. or manufacture new bearings as per your drawings.
- Physical properties such as tensile, creep, and fatigue strength are increased up to 30% Centrifugal metal purity withstands greater overload and strain without fracture.
- No Rejects - Blowholes, porosity, and inclusions are eliminated before finish machining.
- Machining Expenses Reduced - Expensive machining time is not wasted on defective parts and material waste is significantly reduced.
- Production Flexibility - The centrifugal process provides economical production of a diversified range of sizes, and quantities.
Four characteristics emerge from the "molecular packing" action common only to the high-velocity centrifugal process:
- Since the parts are formed under pressures many times that of gravity, they exhibit a denser, closer-grained structure with greatly improved physical properties.
- During spinning, heavier metal is forced outward, displacing the lighter oxides and impurities and causing them to "float" inward toward the central axis to be removed later in the boring operation.
- Unlike conventional gravity or static castings that chill from both the inside and outside surfaces, centrifugals freeze from the outside surface inward. The result is a part free of shrinkage cavities, gas pockets, and blowholes.
- We guarantee 100 percent bond strength in all our bearings and provide ultrasonic test reports along with the relined bearings.
