What Is the 3128307488 Sliding Piece Used For?

The 3128307488 SLIDING PIECE ATLAS COPCO serves as a stabilizing and guiding interface within the sliding assemblies of Atlas Copco hydraulic drifters. It prevents metal-to-metal contact inside the feed mechanism and ensures that the drifter piston travels smoothly within the hammer housing.

Sliding pieces are mission-critical in maintaining:

• Straight, linear motion paths

• Reduced internal vibration

• Controlled movement during impact cycles

• Precision alignment during high-frequency hammering

• Protection of neighboring components from accelerated wear

When a sliding piece becomes worn, it introduces instability to the drifter, often causing:

• Excessive vibration

• Loss of drilling accuracy

• Irregular feed pressure

• Noise increases

• Uneven wear on bushings and pistons

Replacing the sliding piece with a high-quality OEM-equivalent component like 3128 3074 88 restores the drifter’s original mechanical stability and drilling performance.

Compatibility – Which Atlas Copco Models Use 3128307488?

The 3128307488 / 3128 3074 88 SLIDING PIECE is commonly used in mid-range Atlas Copco hydraulic drifters built for drilling systems in underground mining and tunneling.

Compatible models typically include (depending on drilling rig configuration):

• COP 1838

• COP 1838ME

• COP 1838HD

• COP 1838HR

• COP 1838+: Field variants

• Boomer M2 / M2C / M2D rigs equipped with COP1838-class drifters

• Rocket Boomer rigs using the COP1838 series

Note: Compatibility may vary slightly depending on rig year, configuration, and rebuild variant. Customers often verify the component against their drifter’s serial number during procurement.

3GEN Export provides fast assistance for compatibility checks before order processing.

Technical Features of the 3128307488 Sliding Piece

The sliding piece is engineered with a specialized composite material blend formulated for:

• Low friction coefficient

• High surface strength

• Resistance to dust abrasion

• Impact tolerance

• Controlled wear pattern

• Stable expansion behavior under heat

Its geometry includes:

• Precision-machined guide surfaces

• Dimensional consistency for accurate alignment

Mechanical Role Inside the Drifter

1. Guiding Function

The sliding piece functions as the guiding backbone, allowing the piston and carriage system to move linearly without deviation.

2. Stability and Load Distribution

It absorbs and redistributes mechanical load across the drifter housing, minimizing localized stress.

3. Wear Management

Instead of surrounding metal components wearing prematurely, the sliding piece acts as the sacrificial wear component, which can be replaced during maintenance intervals.

4. Vibration Damping

Its material composition reduces high-frequency vibration and noise during drilling.

5. Protection for Internal Components

Prevents galling, scoring, and deformation inside the drifter mechanism.

Why the Sliding Piece Must Be Replaced Regularly

In hydraulic drifters, sliding pieces experience continuous friction, impact resonance, and thermal cycling. Over time, this results in:

• Surface erosion

• Micro-fractures

• Loss of thickness

• Uneven wear marks

• Feeding irregularities

When these symptoms appear, replacing the sliding piece ensures:

• Consistent drilling force

• Prolonged lifespan of pistons and bushings

• Lower lubrication consumption

• Reduced downtime

• Restoration of drilling accuracy
