ATLAS COPCO EPIROC Parts List-16

ATLAS COPCO & EPIROC SEAL KIT ENGINEERING REFERENCE

Atlas Copco and Epiroc seal kits are small component groups, but they have a direct influence on hydraulic pressure retention, oil cleanliness, drilling accuracy and machine availability. In drilling equipment, a seal kit is not only a leakage-prevention item. It works inside a wider hydraulic and mechanical system where pressure, heat, vibration, contamination and surface condition all affect service life.

This Atlas Copco Epiroc Parts List-16 page is focused on seal kits used across hydraulic and rock drill maintenance applications. These kits may be related to hydraulic cylinders, feed mechanisms, rotation assemblies, percussion units, valve blocks, accumulators and other pressure-bearing systems depending on the machine configuration and part number. Correct identification should always connect the part number with the machine model, subsystem and actual service location.

SEAL KIT FUNCTION IN HYDRAULIC AND ROCK DRILL SYSTEMS

Hydraulic systems in drilling machines depend on controlled oil flow and stable pressure. When seals start to harden, wear or deform, the system may lose pressure before a visible external leak appears. This can reduce feed force, affect drill positioning, increase cycle time or create unstable movement in cylinders and actuators. In rock drill assemblies, sealing components also protect the internal oil film from contamination while helping maintain the correct separation between moving surfaces.

A seal kit normally works together with piston surfaces, rods, cylinder barrels, bushings, guides, wipers, O-rings and backup rings. If one of these surrounding components is worn, scratched or misaligned, a new seal kit may fail earlier than expected. For this reason, seal replacement should be treated as a system repair rather than a simple consumable change.

ENTITY RELATIONSHIP: MACHINE, SYSTEM, COMPONENT AND FAILURE

• Drilling Machine → Hydraulic Circuit → Cylinder / Actuator → Seal Kit → Pressure Retention
• Rock Drill → Percussion Movement → Lubrication Film → Internal Sealing → Impact Stability
• Feed System → Linear Movement → Rod Surface → Rod Seal / Wiper → Contamination Control
• Control Valve → Oil Flow Direction → Actuator Response → Seal Condition → Movement Accuracy
• Hydraulic Oil → Filtration → Particle Control → Seal Wear Rate → Service Life

This relationship-based view is important for both maintenance planning and spare part selection. A seal kit number alone may identify the component group, but the real replacement decision depends on how that kit functions inside the equipment system.

COMMON SEAL KIT FAILURE MODES

Seal kit failures in Atlas Copco and Epiroc applications are commonly linked to oil contamination, pressure peaks, excessive heat, poor lubrication, surface scoring or incorrect installation. Abrasive particles can damage sealing lips and create internal leakage. Heat may harden elastomer materials and reduce flexibility. Pressure spikes can extrude seals if backup support is weak or if the seal groove is damaged.

• Internal hydraulic leakage and pressure loss
• External oil leakage around rods, covers or housings
• Seal lip wear caused by abrasive contamination
• Hardening or cracking caused by heat and oil degradation
• Extrusion damage caused by pressure peaks
• Rod or piston scoring that damages new seals
• Wiper failure allowing dust and drilling debris into the system
• Repeated seal failure caused by worn bushings or misalignment

MAINTENANCE CHECKS BEFORE REPLACING A SEAL KIT

Before installing a replacement seal kit, the mating surfaces should be inspected carefully. Rod chrome condition, piston surface quality, cylinder bore wear, groove condition, bushing clearance and oil cleanliness all influence the result of the repair. If these items are ignored, the machine may return to service but the same leakage problem can appear again within a short time.

Recommended checks include hydraulic oil filtration condition, visible contamination in the failed assembly, abnormal heat marks, scoring on moving surfaces, damaged retaining grooves and excessive side load. For drilling machines working in quarry, mining or tunnelling environments, dust and impact vibration should also be considered as part of the failure analysis.

APPLICATION CONTEXT

Seal kits listed in this Atlas Copco Epiroc reference may support equipment used in surface drilling, underground mining, tunnelling, quarry operations, blast hole drilling and infrastructure projects. These environments expose sealing systems to high vibration, fine dust, moisture, long operating hours and rapid pressure changes. Maintenance teams should therefore evaluate seal kits together with hydraulic oil condition, filtration quality and the mechanical condition of related components.

PART IDENTIFICATION AND SUPPLY SUPPORT

Vomeks uses Atlas Copco and Epiroc part numbers as the primary identification reference for seal kit inquiries. When possible, buyers should confirm the machine model, serial number, subsystem location and previous repair history. This helps reduce the risk of selecting a visually similar but technically different seal kit.

Vomeks supports international buyers with OEM-equivalent Atlas Copco and Epiroc replacement solutions, part number verification, cross-reference assistance and worldwide export supply. The purpose of this page is to combine a searchable part number index with practical engineering context so that maintenance teams can evaluate seal kits not as isolated items, but as functional components inside hydraulic and rock drilling systems.
