3115357100, 3115 3571 00 SPRING WASHER ATLAS COPCO

The 3115357100 Spring Washer Atlas Copco (also searched as 3115 3571 00 Spring Washer Atlas Copco) is a precision-engineered mechanical component designed to provide consistent tension, controlled load distribution, and reliable fastening performance in demanding rock drilling environments. This washer plays a critical role inside Atlas Copco drifter assemblies by maintaining bolt torque, absorbing vibration, and protecting core components from premature wear. As an essential part of the tightening system, the 3115357100 Spring Washer Atlas Copco contributes directly to drilling accuracy, structural stability and long-term machine reliability.

Manufactured using premium-grade alloy steel and heat-treatment processes, this washer offers exceptional resistance to deformation, corrosion, cyclic fatigue and high-impact stress—conditions that define heavy-duty mining, quarrying and tunneling work. 3GEN Export supplies this part as an OEM-standard replacement, providing global delivery in just 5 working days, supporting Atlas Copco equipment fleets anywhere in the world.

What Is the 3115357100 Spring Washer Atlas Copco?

The 3115357100 Spring Washer Atlas Copco is a specially shaped, compression-retaining washer designed to secure threaded fasteners in rock drill applications. Unlike flat washers, which only distribute load, a spring washer stores elastic energy and actively maintains tension on the assembly. This is especially valuable in high-vibration systems such as:

• Rock drills

• Drifter mechanisms

• Feed systems

• Percussion assemblies

• Rotation units

When mounted between a bolt head and a joint surface, the 3115 3571 00 Spring Washer Atlas Copco supports consistent preload, preventing bolts from loosening during impact cycles, rapid reciprocation and abrasive drilling operations.

This washer also reduces risk of:

• Bolt back-off under vibration

• Fatigue cracking at the fastening point

• Component misalignment

• Torque instability

• Energy loss in the percussion chamber

Its reliability under stress makes it indispensable for maintaining safe and efficient drilling operations.

Key Features of the 3115357100 Spring Washer Atlas Copco

High-Strength Alloy Steel Construction

The 3115357100 Spring Washer Atlas Copco is produced from hardened alloy steel, engineered for superior tensile strength, elasticity and deformation resistance. The controlled heat-treatment process helps the washer retain spring force over thousands of compression cycles.

Precision Machined for Accuracy

Every washer undergoes CNC machining to achieve exact thickness, diameter and angular tolerances. This precision ensures:

• Smooth seating

• Balanced load distribution

• Compatibility with OEM bolt systems

• Stable torque retention

Anti-Vibration Performance

The core purpose of a spring washer is to counteract vibration-induced loosening. The design of the 3115 3571 00 Spring Washer Atlas Copco makes it ideal for:

• High-frequency percussive drilling

• Rotational energy transfer systems

• Reversing loads

• Rapid impact cycles

Corrosion-Resistant Surface

To handle moisture, dust, mud and drilling fluids, the washer is surface-treated to enhance corrosion resistance. This extends service life and helps maintain consistent torque even in harsh environments.

OEM Compatibility with Atlas Copco Systems

The washer is fully compatible with multiple Atlas Copco rock drill platforms, making it ideal for maintenance teams, workshops and fleet operators who require OEM-standard reliability without premium pricing.

Benefits of Using the 3115 3571 00 Spring Washer Atlas Copco
