3222 3078 39 COUPLING CENTAFLEX ATLAS COPCO – High-Performance Vibration-Isolating Coupling for Rock Drilling Systems

The 3222 3078 39 COUPLING CENTAFLEX ATLAS COPCO is a premium-grade, torsionally flexible rubber coupling used across Atlas Copco’s rock drilling and heavy machinery systems. Its purpose? To absorb torque shocks, reduce system vibrations, and provide reliable mechanical flexibility in rugged, high-vibration applications such as surface drilling rigs, underground jumbos, and hydraulic systems.

Crafted using high-durability elastomers and reinforced with precision-engineered steel inserts, this CENTAFLEX coupling ensures seamless torque transmission even under misalignment, vibration, or rotational load. It’s the go-to solution for reducing wear on drive components and minimizing costly downtime in harsh operational environments.
