High Strength 23CrNi3Mo Shank Adapter With 770mm Length And T51 Type For Atlas Copco COP2160EX
In the demanding environment of mining and bench drilling, the shank adapter (striking bar) acts as the critical bridge between the rock drill's piston and the drill string. A high quality adapter not only accelerates your penetration rate but also protects your expensive rock drill equipment from premature wear.
Specifically designed for the Atlas Copco COP 2160EX series, our shank adapters are engineered to withstand extreme impact energy and high torque. Here's why global mining contractors prefer our solutions:
- Superior Material Heat Treatment : Manufactured from premium 23CrNi3Mo alloy steel, each adapter undergoes a full carburizing process. This ensures a perfect balance — a hard, wear-resistant surface with a flexible core to prevent snapping.
- Precision Engineering : Utilizing advanced CNC machining, we guarantee the accuracy of internal and side water holes. Each unit is scientifically straightened to minimize friction and energy loss.
- Optimized Hardness (HRC38 - 45) : We maintain a strict hardness profile slightly lower than the piston's. This "sacrificial" design protects your rock drill's piston from damage, significantly reducing maintenance costs.
- Zero Tolerance Fit : Our adapters ensure a gap of less than 0.5mm with the drill sleeve, ensuring maximum energy transfer and straighter holes.
Ideal for bench drilling and heavy duty mining projects. Beyond the COP2160EX - T51 series, Henglong Factory offers a comprehensive catalog of over 300 types of shank adapters compatible with major brands like Sandv, Epiroc (Atlas Copco), and Montabert.
