Premium Aftermarket Drill Rig Hydraulic Cylinders for Mining & Quarrying

SEIGO Machinery manufactures direct-replacement drill rig hydraulic cylinders for surface blasthole and down-the-hole (DTH) drills. From feed and mast cylinders to rod-handling and leveling jacks, we supply the full hydraulic package for Atlas Copco / Epiroc and Sandvik drills — engineered to keep drilling through the dust, shock and vibration of hard-rock mining.

Our Product Range

A drill rig runs on dozens of specialized cylinders. We manufacture the complete set, grouped by function:

  • Feed & Mast Cylinders — feed (rod advance), carriage lift and swing, mast raise and mast-lock cylinders.
  • Boom & Positioning Cylinders — boom lift, pitch, swing, rotation and fine-positioning cylinders for accurate hole alignment.
  • Rod-Handling & Manipulator Cylinders — rod loader/manipulator, rod clamp (long & short), breakout and carousel cylinders for automated rod changing.
  • Leveling & Jack Cylinders — front and rear leveling jacks and body-leveling cylinders for stable setup on uneven ground.
  • Auxiliary Cylinders — chain-tensioning, dust-hood and curtain, and other machine-specific cylinders.

Why Choose SEIGO Cylinders?

Unlike generic replacements, every SEIGO cylinder is built “Mining-Ready”:

  • Built for abrasive, high-vibration duty — drill-rig cylinders engineered for constant shock, dust and vibration on the bench.
  • Material excellence — 42CrMo4 induction-hardened piston rods with hard chrome plating resist scoring and grit.
  • Superior sealing — NOK or Parker seal kits to keep dust out and pressure in through long drilling shifts.
  • Rigorous testing — 100% pressure-tested at 1.5× operating pressure before shipment.
  • Warranty — backed by a 12-month / 2,000-hour warranty.

Whether you need a single feed cylinder to get a rig back on the bench or a full set for a fleet rebuild, SEIGO keeps your drills turning and your downtime low.
