CONNECTING ROD is a very important component of internal combustion engine because it connects piston to crankshaft. Connecting Rod converts reciprocating motion into rotary motion.

We manufacture and supply precision and quality construction of Connecting Rod . We make our products to maximize strength, durability & high accuracy.

Connecting Rod forms the heart of any Internal Combustion Engine, which is an integral part of Cars, Tractors, Trucks, Ship etc. It transforms the circular motion of crankshaft into reciprocal motion thereby moving the piston to create the compressive strength to start and accelerate the engine. Material used for this component commonly CK45, EN-16, EN-9 or as per customer requirement etc.

UMA INDUSTRIES manufactures closed die forged CONNECTING RODS from Alloy Steel materials as per recommended O.E. Specification.

T he Bolts used are made from high tension steel material. The Bush is supplied by some of the leading manufacturers of the country, as per O.E. Specification. We also utilize gunmetal bushes.
