Overview of 3115296800 , 3115 2968 00 CHUCK BUSHING ATLAS COPCO

The 3115296800 , 3115 2968 00 CHUCK BUSHING ATLAS COPCO acts as a precision bearing and protective sleeve inside the rock drill’s rotation mechanism. During high-impact operations, it supports the chuck assembly by absorbing frictional forces and vibration, keeping the rotating components perfectly aligned.

Without this bushing, direct metal-to-metal contact could cause accelerated wear of the chuck and shaft, leading to performance degradation and mechanical failure. By maintaining smooth rotational balance, it ensures steady torque transmission, improved drilling accuracy, and extended component lifespan.

Engineered from hardened alloy steel and finished with advanced surface treatments, this bushing operates efficiently under high pressures, temperatures, and impact frequencies — making it ideal for demanding mining and construction environments.

Engineering and Manufacturing Excellence

Precision Machining

Each 3115296800 , 3115 2968 00 CHUCK BUSHING ATLAS COPCO is machined using CNC-controlled multi-axis systems that ensure dimensional tolerances within ±0.01 mm. The fine-tuned geometry guarantees a perfect fit within the chuck housing, preventing vibration and backlash during operation.

Material Selection

The component is constructed from hardened chromium-molybdenum alloy steel (42CrMo4), known for its exceptional fatigue resistance, tensile strength, and ability to withstand cyclic loading. The inner and outer diameters are precision-ground and polished to maintain smooth, consistent lubrication flow.

Surface Hardening

The bushing undergoes a dual-stage heat treatment process, combining induction hardening and tempering, resulting in a surface hardness of 58–62 HRC. This treatment provides exceptional resistance against scoring, deformation, and micro-pitting even in high-impact cycles.

Corrosion Protection

A micro-layer of anti-corrosive coating prevents oxidation, enabling optimal performance in wet or dusty environments. This feature is particularly beneficial for rock drills operating in humid underground or open-pit mines.

Functional Importance in Drifter Systems

In Atlas Copco drifters, the 3115296800 , 3115 2968 00 CHUCK BUSHING ATLAS COPCO serves as a key element in the rotational mechanism. It stabilizes and aligns the chuck, enabling consistent axial motion of the drill rod and preventing unwanted deviation.

Core Functions:

• Alignment: Maintains the concentricity between the chuck and the drive shaft.

• Wear Reduction: Acts as a buffer that absorbs frictional energy during high-speed rotation.

• Lubrication Retention: Retains and distributes lubricant evenly across contact surfaces.

• Energy Efficiency: Reduces internal resistance, allowing more power to transfer to the drill bit.

• Vibration Dampening: Minimizes the effects of high-frequency vibration, preserving structural integrity.

The bushing’s role extends beyond protection — it’s a key determinant of drilling precision, energy efficiency, and mechanical longevity.

Operational Advantages

1. Extended Component Life

The hardened steel structure and precise oil-retaining finish minimize direct friction, allowing the chuck and shaft to last longer even under continuous load cycles.

2. High Impact Resistance

The bushing’s metallurgy and surface treatment allow it to absorb shock loads of up to 25 kN without deformation, ensuring reliability during heavy-duty percussive drilling.

3. Enhanced Efficiency

Reduced friction translates directly into lower energy loss, maximizing the power transmitted from the hydraulic motor to the drill bit.

4. Smooth Drilling Operation

The precision finish ensures stable and vibration-free chuck motion, resulting in cleaner boreholes and improved drilling accuracy.

5. Maintenance-Free Durability

Once installed, the bushing requires minimal maintenance thanks to its self-lubricating properties and high wear resistance.

Installation and Maintenance Guide

Installation Instructions

1. Clean the chuck housing thoroughly before inserting the bushing.

2. Lightly lubricate both the bushing’s outer surface and the chuck bore.

3. Insert manually until aligned, then press-fit using the specified installation tool.

4. Ensure full seating and alignment before reassembling the drill head.

5. Test the rotation system under low hydraulic pressure before resuming operation.

Maintenance Tips

• Periodically check clearance between the bushing and shaft (recommended tolerance: 0.02–0.04 mm).

• Maintain proper lubrication levels using Atlas Copco-approved grease.

• Replace immediately if wear marks or scoring become visible on the bore surface.

Following these procedures ensures optimal drilling performance and prevents unexpected breakdowns.
