Hydraulic Cylinder Engineering for the Mining Industry

Servicing Logan, Brisbane & the Gold Coast Areas

Oz Engineering specialises in Hydraulic Cylinder Engineering tailored for the mining sector, delivering robust, reliable, and high-performance hydraulic solutions built to withstand the harshest operating environments. From open cut mines to underground operations, we support mining companies, contractors, and heavy equipment operators with fast turnaround hydraulic repairs, rebuilds, machining, fabrication, and custom component manufacturing.



Mining machinery operates under extreme pressures, abrasive conditions, and continuous heavy loads. Our team ensures every hydraulic cylinder, rod, barrel, and component is engineered to handle demanding mining applications—including loaders, excavators, underground trucks, drills, longwall systems, and fixed plant equipment.

Servicing Logan, Brisbane and the Gold Coast Areas, Oz Engineering is a trusted partner for mining operations seeking durability, precision, and reliability.

Why Mining Operators Choose Oz Engineering for Hydraulic Cylinder Engineering

Mining operations depend on equipment that cannot fail. Unplanned downtime due to hydraulic cylinder faults can halt production, create safety hazards, and lead to significant financial loss. Oz Engineering delivers:


  • Fast turnaround times to reduce downtime
  • High-accuracy machining for long-lasting performance
  • Quality repairs capable of withstanding demanding mining loads
  • Custom-built hydraulic components to OEM or improved specifications


Engineering enhancements to increase service life in harsh conditions

With deep experience working on mining machinery and plant equipment, our team understands the unique challenges mining presents—abrasion, corrosion, high-pressure loading, temperature extremes, and continuous duty cycles.

Hydraulic Machining & Custom Component Manufacturing for Mining

We manufacture and repair hydraulic components built for mining resilience, including:


  • Hydraulic cylinder rods (hardened and precision ground)
  • Heavy wall barrels and tubes
  • Pistons, glands, and clevis ends
  • Threaded and welded cylinder components
  • High-tolerance pin and bush assemblies


Our machining capabilities include CNC and manual turning, milling, drilling, honing, and surface finishing. Every component is engineered to maintain strength, performance, and reliability under the extreme forces of mining equipment.

Mining Hydraulic Cylinder Repairs & Breakdown Response

Mining equipment breakdowns require immediate action. Oz Engineering specialises in:


  • Full hydraulic cylinder rebuilds
  • Resealing and seal upgrades for abrasive environments
  • Rod straightening, manufacturing, and chrome preparation
  • Barrel honing, sleeving, and re-machining
  • Structural repair of damaged lugs, ports, and end caps
  • Failure analysis and preventive engineering improvements


Whether it’s a blown cylinder on a loader, cracked barrel on a haul truck, or worn rod on a drill rig, we provide fast, durable repairs to keep equipment operational.

Custom Fabrication, Heavy-Duty Welding & Mining Fitment

Mining environments demand strength, and our fabrication capabilities are designed to meet those needs:


  • Heavy-duty welded hydraulic components
  • Frames, mounts, brackets, and structural supports
  • Wear-resistant guarding and protection systems
  • Custom engineering modifications for harsh conditions
  • Precision fitment for large and complex assemblies


All work is performed to meet mining compliance, safety standards, and OEM requirements.

On-Site & Mobile Hydraulic Support for Mining Equipment

When mining equipment is too large to move—or when downtime must be minimised—our mobile team provides:


  • On-site hydraulic cylinder removal and refitting
  • Minor cylinder repairs and resealing
  • Welding, machining, and fitment work in-field
  • Site-based adjustments, inspections, and troubleshooting
  • Support for shutdowns, planned maintenance, and emergency repairs


This ensures mining operations can continue with minimal interruption.
