3217 8525 02 WASHER

3217 8525 02 Washer Atlas Copco – Premium Load-Bearing Ring for Driller Assemblies

The 3217 8525 02 Washer Atlas Copco is a precision-engineered ring designed for heavy-duty drilling systems. Crafted from high-carbon alloy steel and finished with corrosion-resistant treatment, this washer serves as a critical load-bearing shim between joint surfaces in rock-drilling repositor systems. Its flat, polished surfaces ensure even pressure distribution, prevent metal galling, and maintain precise alignment throughout thousands of impact cycles.

🛠️ Purpose & Functionality

The 3217 8525 02 Washer Atlas Copco serves several vital roles:

1. Even Load Distribution
   When installed between mating components, it spreads compressive loads over a broader surface, protecting softer metals from damage.

2. Precision Alignment
   The washer helps maintain consistent axial clearance, keeping pistons, liners, and bushings aligned under harsh conditions.

3. Vibration Dampening
   By acting as a shim, it absorbs minor shocks and vibrations from impact drilling, helping preserve tight joint connections.

4. Wear Resistance
   The polished, hardened surfaces resist frictional wear and galling, extending the life of bolted or pressed assemblies.

5. Thermal Expansion Control
   It stabilizes gaps under temperature shifts, preventing misalignment during hot-down or cold-up cycles.
