3115 0821 00 SHAFT ATLAS COPCO – OEM Rock Drill Transmission Precision by 3GEN Export

When it comes to high-impact drilling operations, every component within your machinery must work in perfect synchrony to ensure peak performance. One such vital component is the 3115 0821 00 SHAFT ATLAS COPCO, engineered to withstand the demanding conditions of rock drilling applications in heavy-duty environments. This shaft plays a critical role in torque transmission within the drifter assembly, enabling smooth and precise power transfer between mechanical parts.

Engineered for Strength and Endurance

Manufactured from hardened, high-grade alloy steel, the 3115 0821 00 SHAFT ATLAS COPCO is precision-machined to ensure optimal fitment and performance. The shaft’s surface is finished with anti-corrosive treatment and heat-treated splines for enhanced resistance against wear and mechanical fatigue. Its hardened profile guarantees consistent reliability even under the most intense vibratory and rotational stress levels encountered during deep rock boring tasks.

Functional Purpose in Rock Drill Assemblies

This shaft serves as a rotational intermediary between the hydraulic motor and key rotary components of the rock drill. By transferring torque smoothly without compromise, the 3115 0821 00 SHAFT ATLAS COPCO ensures efficient energy delivery, minimized vibration, and improved operational accuracy in Atlas Copco hydraulic drifters.

Key functions include:

• Transmission of mechanical power from the motor to the drill feed

• Absorption of axial and torsional loads

• Precision alignment for smoother motion and tool longevity
