ATLAS COPCO EPIROC PARTS LIST 7

ATLAS COPCO & EPIROC PARTS LIST 7 – ENGINEERING REFERENCE

This Atlas Copco and Epiroc parts list is focused on components that are commonly connected with rock drill sealing, flushing, rotation drive support, pressure indication and equipment monitoring. Diaphragms, repair sets, flush head components, rotation chucks, sprocket wheels, sliding pieces, pressure gauges, nozzles, sensors and relays do not work as isolated spare parts. They are part of a wider drilling system where hydraulic pressure, flushing flow, percussion energy, feed movement and rotation torque must remain balanced during operation.

For maintenance teams, the value of this page is not only the part number list. The engineering context is important because a damaged diaphragm, worn sliding piece, leaking flush head or inaccurate pressure gauge can affect drilling performance, flushing efficiency, bit life and machine reliability. Correct identification should therefore consider the machine model, drill unit, operating environment, previous repairs and the subsystem in which the component is installed.

COMPONENT FUNCTION AND SYSTEM RELATIONSHIP

In Atlas Copco and Epiroc rock drilling equipment, flushing, rotation and pressure control systems work together continuously. The flush head directs air or water flow toward the drill string to remove cuttings from the hole. Rotation chucks transfer rotary motion to the drill steel while remaining exposed to impact vibration and abrasive contamination. Diaphragms and repair sets help maintain sealing behaviour inside pneumatic, hydraulic or control-related assemblies. Sensors, thermostats, relays and pressure gauges provide feedback that helps operators and technicians understand the actual condition of the machine.

• Diaphragm and repair set: support pressure separation, sealing stability and control response inside serviceable assemblies.
• Flush head component: directs flushing media and helps maintain hole cleaning efficiency during drilling.
• Rotation chuck: transfers rotation torque to the drill string while operating under vibration and impact load.
• Sprocket wheel and sliding piece: support feed, guide or movement-related mechanisms depending on machine configuration.
• Pressure gauge and sensor: help monitor hydraulic, pneumatic or temperature-related operating conditions.
• Nozzle: controls flow direction, cleaning performance or lubrication distribution according to the application.

FAILURE MODES IN DRILLING APPLICATIONS

Components in this group are exposed to a combination of high-frequency vibration, abrasive dust, water, oil contamination, temperature variation and repeated pressure cycles. A failure may start as a small leakage, reduced flushing flow, abnormal pressure reading or increased chuck wear, but it can gradually create larger problems in the drilling system. For example, a blocked or worn nozzle may reduce cleaning efficiency; poor flushing can increase heat and abrasive wear around the drill steel; excessive vibration can accelerate damage on rotation chucks, sliding pieces and adjacent guide components.

• Diaphragm cracking or hardening caused by pressure cycling, ageing or chemical exposure.
• Flush head leakage caused by seal wear, surface scoring or abrasive particles in the flushing media.
• Rotation chuck wear caused by vibration, misalignment, poor lubrication or drill string load.
• Sliding piece wear caused by guide contamination, side loading or insufficient lubrication.
• Incorrect pressure indication caused by damaged gauges, blocked lines or sensor failure.
• Nozzle restriction caused by contamination, scale, deformation or operating debris.
• Relay or sensor faults causing unreliable machine feedback or delayed troubleshooting.

MAINTENANCE AND TROUBLESHOOTING CONTEXT

When one of these components is replaced, the surrounding system should also be inspected. A new flush head component may fail early if the sealing surface is scored or if abrasive particles remain in the flushing circuit. A replacement rotation chuck may not solve repeated wear if the drill string is misaligned, lubrication is insufficient or the feed system has excessive play. Pressure gauges and sensors should be checked together with hoses, fittings and control lines because false readings may lead to incorrect adjustment decisions.

PART IDENTIFICATION APPROACH

Atlas Copco and Epiroc part numbers may appear with spaces, without spaces or in compact number format depending on catalogues, labels, old documents and supplier references. For accurate identification, the part number should be matched together with the part name, machine model, drill unit type, serial range and component position. This is especially important for rotation chuck assemblies, flush head versions, repair sets and sensor-related components because small design differences can affect compatibility.

Vomeks organizes this index as a technical reference for professional buyers, workshops and maintenance departments. The purpose is to make part number identification easier while explaining how the listed parts relate to drilling performance, sealing integrity, flushing flow, pressure control and equipment reliability.

APPLICATION ENVIRONMENT

The parts listed on this page are typically associated with Atlas Copco and Epiroc equipment used in surface drilling, underground drilling, tunnelling, quarrying, mining maintenance and heavy-duty construction applications. Dust concentration, drilling angle, rock hardness, water quality, hydraulic temperature, flushing pressure and production cycle length can all influence service life. For that reason, replacement planning should be based on both part number accuracy and the real operating conditions of the machine.
