Wire Coil: Steel wire of specific material and size is checked for correctness.
Cutting: The wire is cut into required lengths.
Forging / Heading: Spherical shapes between dies are formed.
Deflashing: The flash line along the circumference is removed.
Heat Treatment: Chrome and bearing steel balls are thorough hardened.Â
Cleaning / Descaling: Basic surface cleaning is done.
Hard Grinding / Filing: An exacting process to achieve required sphericity and size of the steel ball.
Lapping: The final surface finish is acquired through this process.
Polishing / Burnishing: Surface lustre, work hardening, higher product life is achieved.
 Passivation: Carryover iron and other contaminants are removed and a surface film prevents atmospheric and water corrosion on stainless steel balls.
Inspection: For surface finish, size and tolerance.Â
Rust preventive oil: Applied on chrome alloy steel balls to save from rusting and corrosion.
Packing: Done as per requirement in numbers, pieces or by weight. VCI paper or bags are used wherever necessary.
Certificate display
The best steel, pre-tested, is used with modern production, inspection procedures.
Proprietary polishing, lapping processes employed, result in world class finishes.
Strict quality control and inspection at each stage ensures that each steel ball whichÂ
finally rolls out, conforms to the required quality and specification.
The steel ball are offered in a wide range
Of  material compositions in chrome, bearing, inox and stainless steel;
In sizes ranging from 1 mm to 12.7 mm and 3/64" to 1/2" diameters;
And Grade 100 to 2000, which basically denotes the tolerance and surface finish.
