Piston Rings
PISTON RINGS
SUPER CIRCLE's automotive venture began with the production of piston rings over 40 years ago. The company now manufactures piston rings which are used in tractors, cars, heavy and light commercial vehicles, two wheelers, industrial engines and compressors. With special expertise in production of piston rings for tractor applications, the company's products are used in Massey Ferguson/Perkins, Ford, Fiat, International Harvestor and Zetor among others.
Over 75% of the piston rings production is being exported mainly to countries in Europe and America. There are OE supplies to many companies in India as well as overseas. The rest piston rings are being supplied to government departments and other markets.
All the piston rings are designed with latest techniques like AutoCAD by the engineering staff for maximum efficiency over the life of the engine. Each piston ring is made from highest quality raw materials and machined to OEM standards. Statistical Process Control has been applied at all critical processes to control the quality of the piston rings. The company has a very progressive environment, where all members, from machine operators to top management personnel are involved in contributing to achievement of the quality objectives.
With over 150 employees involved in production and despatch of piston rings, the strictest quality control measures are followed for all the parameters:
Closed gap
Axial width
Radial depth
Chemical Composition
Microstructure
Hardness
Tangential tension
Light tightness
Keystone angle
Cross sectional dimensions
Coating thickness
Surface roughness
Flatness
Parallelism
Tensile strength
Modulus of elasticity
