Connecting Rod

– Water steam treated, low friction and light weight design with high lubricity.

– Roughness and Cylindricity maintained up to 3.5µm, roundness is about 2.50 µm, and maximum precision level maintained about 0.7µm.


In a reciprocating compressor Connecting Rod transfers rotary motion from crankshaft as a reciprocating motion to piston. The connecting rod of our compressor is made of Sintered Iron. It can withstand force up to 240 MPa. Its damping capability is also very good.
