3216294900 – 3216 2949 00 PIN ATLAS COPCO

3216 2949 00 PIN ATLAS COPCO – Precision-Machined Rock Drill Pin for High-Performance Drifters

The 3216 2949 00 PIN ATLAS COPCO is a core structural and guiding component engineered for the heavy-duty internal assemblies of ATLAS COPCO hydraulic drifters. Manufactured with extremely tight tolerances, this pin plays a crucial role in maintaining alignment, impact stability, and movement precision inside the drifter’s percussion and rotation system. Designed to withstand the brutal dynamics of rock drilling and mining operations, the 3216294900 pin ensures that the drifter operates with maximum efficiency, minimal vibration, and long-term structural stability under sustained high-impact loads.

As an internal mechanical element, this pin is exposed to repetitive shock frequencies, rotational forces, lubrication cycles, and sliding contact. For this reason, 3GEN Export supplies this component using only high-grade alloy steels, controlled heat-treating cycles, and perfectly polished machining lines — guaranteeing that every pin reliably fits into its designated bore with the correct interference tolerance and alignment accuracy.

Whether you operate a quarry, mining fleet, tunneling project, or drilling contractor, the 3216 2949 00 PIN ATLAS COPCO ensures your drifters run smoother, last longer, and maintain consistent striking energy. With ATLAS COPCO drifters frequently running thousands of percussive cycles per minute, even a small deviation or worn pin can cause misalignment, accelerated wear, and expensive system downtime. This makes the replacement of internal pins one of the most critical predictive-maintenance tasks in rock drilling.

What the 3216 2949 00 PIN Does Inside Your ATLAS COPCO Drifter

The 3216 2949 00 pin is used in the internal guiding, retention, or connection assemblies within ATLAS COPCO drifters. Depending on the drifter model, this pin may serve one or more of the following structural and functional purposes:

1. Alignment Control

This pin helps maintain the internal alignment of moving assemblies such as:

• Piston guides

• Housing brackets

• Rotation sleeves

• Shuttle or valve cages

Proper alignment ensures that the piston moves linearly and that rotation torque remains stable during drilling.

2. Structural Retention

The 3216 2949 00 pin also functions as a retention element, preventing internal components from rotating, drifting, or loosening under shock loads. Drifters operate at impact frequencies exceeding 50–60 Hz, making internal retention absolutely critical.

3. Vibration Absorption Assistance

Because the pin is made of heat-treated alloy steel, it absorbs a portion of the micro-vibrational energy within the drifter body, reducing fatigue stress and prolonging the lifespan of mating components.

4. Lubrication and Flow Integration (via Side Bore Hole)

The hole machined through the pin is a functional feature used for:

• Grease passage

• Oil flow distribution

• Ventilation

• Retainer-bolt engagement

This precise geometry ensures the lubrication circuit remains continuous, preventing dry-running conditions that could lead to premature scoring or galling.

Material Engineering & Manufacturing Quality

The 3216 2949 00 PIN ATLAS COPCO is manufactured using a multi-stage industrial process that ensures maximum durability:

Selected specifically for rock-drill requirements, the alloy delivers:

• High tensile strength

• Excellent fatigue resistance

• Superior sliding-surface durability

• Hardness retention under heat

Heat Treatment Process

Each pin undergoes:

• Induction hardening

• Core stabilization

• Tempering at controlled temperatures

This process produces:

• A tough, impact-resistant core

• A hardened exterior surface

• Perfect microstructural consistency

CNC Machining to Micron-Level Precision

To ensure perfect compatibility, 3GEN Export supplies pins with:

• Perfectly centered lubrication/retention bores

• Burr-free edges

• Strict tolerance within ATLAS COPCO specifications

• Precision-ground outer diameter

This ensures zero misalignment during installation.

Why the 3216 2949 00 PIN Matters for Drifter Health

Replacing internal pins is essential for preserving drifter performance. A worn or undersized pin can cause:

• Piston misalignment

• Uneven striking surfaces

• Loss of drill power

• Damage to rotation components

• Increased vibration

• Premature wear of expensive assemblies

By installing a new 3216 2949 00 PIN ATLAS COPCO, you instantly restore mechanical stability and protect the drifter from catastrophic failure.
