Function and Role in Hydraulic Drifters

The 3115 2117 89 STOP RING ATLAS COPCO acts as a locking and positioning component inside the hydraulic drifter housing. In the Atlas Copco percussion system, it retains the moving parts in their designated axial positions, preventing unwanted displacement during repeated impact cycles.

Hydraulic drifters like those in the COP series rely on precision synchronization between moving elements—piston, shank adapter, bushings, and chuck components. A stop ring secures these parts against axial drift, which would otherwise cause loss of energy transfer, mechanical imbalance, or catastrophic failure.

By providing a mechanical limit to motion, the stop ring ensures:

• Stable positioning of internal components

• Consistent impact alignment between piston and shank adapter

• Reduction of wear on adjacent parts

• Protection of seals and internal bearings

• Smoother percussion cycles

This makes the 3115211789 STOP RING ATLAS COPCO an indispensable part of the hydraulic drifter’s operational integrity, extending the equipment’s service life and maintaining optimal drilling precision.

Material and Construction

The 3115211789 , 3115 2117 89 STOP RING ATLAS COPCO is crafted using hardened chromium-molybdenum steel, renowned for its superior mechanical strength and fatigue resistance. This alloy composition ensures excellent resilience under high-impact conditions while maintaining precise elasticity—critical for locking and absorbing axial forces.

Key Design Features:

• Split-Ring Construction: The stop ring is split into symmetrical halves to allow easy installation and removal within the drifter housing without full disassembly.

• Precision-Ground Contact Surfaces: Each face is machined and polished to micron-level smoothness to reduce wear and maintain perfect seating.

• High Elastic Modulus: The material’s elasticity ensures the ring maintains clamping tension even under continuous load cycles.

• Thermal Stability: The component retains its mechanical properties at elevated drilling temperatures, ensuring consistent performance across various operating conditions.

These attributes make it one of the most reliable retaining components in modern rock drilling systems, ensuring both operational stability and maintenance efficiency.

Manufacturing Excellence and Quality Control

Each 3115 2117 89 STOP RING ATLAS COPCO manufactured under 3GEN Export’s OEM-grade standards goes through an advanced production process that guarantees consistent quality, dimensional accuracy, and metallurgical integrity.

Manufacturing Stages:

1. Forging and CNC Shaping: High-strength steel blanks are forged under controlled temperature conditions, then CNC-machined for dimensional precision.

2. Heat Treatment: The component is induction hardened and oil quenched to enhance wear resistance and structural stability.

3. Grinding and Lapping: Each surface undergoes fine grinding and lapping for perfect roundness and flatness.

4. Inspection: Using 3D coordinate measuring machines, dimensional checks ensure tight tolerance adherence.

5. Surface Treatment: A specialized anti-corrosion coating is applied to improve longevity and reduce oxidation under harsh environments.

Every batch is subjected to tensile testing, Rockwell hardness testing, and non-destructive ultrasonic examination to ensure absolute reliability before global dispatch.
