Hard Chrome Plated Rods
Precision ground and induction-hardened chrome bars offering superior corrosion and wear resistance
Service overview
Overview :
At MCS Hidrolik ve Pnömatik, we manufacture high-precision hard chrome plated rods engineered specifically for hydraulic cylinder pistons and linear motion applications. Built to withstand aggressive industrial environments, our chrome rods provide maximum resistance to wear, mechanical stress, and severe corrosion.
Technical Superiority :
Utilizing advanced induction hardening and precision centerless grinding, our rods feature extreme surface hardness, tight dimensional tolerances, and a mirror-like micro-finish. This combination minimizes seal friction, prevents oil leakage, and significantly extends the operational lifespan of hydraulic machinery.
