What Is the 3115 2117 89 STOP RING ATLAS COPCO?

The 3115 2117 89 STOP RING ATLAS COPCO is a precision-machined mechanical ring designed to limit movement along a shaft or inside a housing. Commonly deployed in the bearing assemblies and rotating substructures of hydraulic rock drills, this part ensures the alignment, safety, and operational accuracy of key components in Atlas Copco systems.

It acts as a mechanical “limit,” preventing excessive inward or outward travel of components like sleeves, bushings, or spacers. This part becomes essential in repetitive, high-impact cycles typical of drilling operations, where component shift—even by millimeters—can lead to operational failure or reduced efficiency.

Technical Specifications

The 3115 2117 89 STOP RING ATLAS COPCO is produced from high-grade, wear-resistant alloy steel, chosen specifically for its ability to retain shape and resist shearing forces in high-torque and high-vibration environments. Key specifications include:

• Material: High tensile alloy steel, surface hardened

• Outer Diameter: Precision cut to fit Atlas Copco bearing housings

• Inner Diameter: Calibrated to snugly fit around the shaft or sleeve

• Split Design: Two-part structure enables easier installation without dismantling surrounding assemblies

• Finish: Anti-corrosion coating with precision grinding for secure locking

• Performance Range: Tested to endure extreme loads during drilling cycles

• Weight: Engineered to be light enough not to disrupt rotational balance, yet robust enough to prevent distortion

This unique combination of strength, precision, and durability allows the 3115 2117 89 STOP RING ATLAS COPCO to serve as a failsafe in rock drills, extending the operational life of associated parts and improving long-term reliability.
