234 387 71 PIN SANDVIK

234 387 71 PIN SANDVIK – OEM Rock Drill Component by 3GEN Export

The 234 387 71 PIN SANDVIK is a precision-engineered mechanical component, crafted for robust and heavy-duty rock drilling operations. It plays a pivotal role in connecting, aligning, or transferring motion within a wide range of Sandvik rock drill systems. As a central fastening and structural part, this pin ensures machine stability, torque resistance, and operational continuity even in the most rugged conditions of quarrying, tunneling, and mining.

Designed with hardened alloy steel, this pin offers unmatched resistance to wear, fatigue, and mechanical shock, which are frequent occurrences in rock drilling machinery. Its cylindrical design with a conically tapered or threaded end allows secure and exact fitting into bores, sockets, or guide systems. This specific geometry ensures minimal clearance, reducing vibrations and preventing component misalignment during long drilling cycles.

Key Features of 234 387 71 PIN SANDVIK

• Part Number: 234 387 71

• Material: High-strength, thermally treated alloy steel

• Surface Finish: Precision-ground with anti-corrosion coating

• Design: Dual-ended – conical and threaded for secure integration

• Weight Class: Optimized for handling both axial and radial stress

• Threading Type: Internal female threading for rigid locking with mating parts

Functionality & Application

The 234 387 71 PIN SANDVIK is primarily used as a rotation and locking pin within rod changers, drifter frames, or hammer assemblies in Sandvik rock drilling machines. It plays a crucial role in maintaining the correct spatial relationship between interlinked parts, ensuring that rotation, percussion, and feeding forces are transmitted efficiently.

In operations that involve cyclic loads, temperature fluctuation, and repetitive assembly/disassembly – such as those found in the mining and infrastructure development sectors – this pin maintains dimensional stability and secure joint integrity.
