CULTIVATING FUTURE WITH WORLD-CLASS TECHNOLOGY

RINGS RANGE STARTING FROM 10MM TO 300MM

INTRODUCTION

With over 64 years of experience in the Piston Ring industry, OAM SAAI INTERNATIONAL INC. is a leader in Quality Piston Ring manufacturing from India exporting to more than 35 Countries Worldwide. Under our brand name ‘CROME’ We manufacture Piston rings ranging from Dia – 10MM to 300MM for all industrial and automotive applications.
With our extensive sales and marketing network, CROME is known for QUALITY and REALIABILITY in the international market with over 200 employees involved in production and dispatch creating a turnover that exceeds 5 million US DOLLARS. Our company ensures that a high degree of quality control is being exercised at every stage of production and inspection.

Piston rings and their application
Piston rings are metal seals which are to prevent leakages and gas blow-by between the combustion chamber and the crankcase as well ensure heat transfer from the piston to the cylinder. Moreover, the piston rings prevent the oil excess necessary for correct functioning of the system piston ring – piston – cylinder from leaking to the combustion chamber and create a uniform oil film on the cylinder working surface (see Fig. 1.3).

In order to do that, the piston rings must be in contact with the piston working surface and with side surface of the piston groove. Radial action is provided mainly by natural spring force of the ring. Gas pressure in the combustion chamber increases radial (to the piston groove) and axial thrust, which improves the ring compression properties. Axial pressure alternates between the upper and the lower piston groove surface due to the action of gases, inertia and the friction force (see Fig. 2.3).
