Epiroc Bolt Cylinder 3128310350 | For Simba H1252/H1254 | Rock Bolting System Hydraulic Assembly

We supply genuine Epiroc bolt cylinders (Part# 3128310350), the core hydraulic component for rock reinforcement systems in Simba H1252 and H1254 production drilling rigs. This precision assembly combines a 80mm bore cylinder with integrated rotation mechanism that delivers 25kN thrust force at 250 bar while simultaneously rotating bolts at 120 RPM. Designed for underground mining efficiency, it installs resin anchors and mechanical bolts from 1.8m to 5m lengths in a single automated cycle.

The cylinder features a hard-chrome plated piston rod (HRC 62 surface) with triple-seal protection against silica dust ingress in >200g/m³ environments. Pre-loaded nitrogen accumulators provide smooth deceleration during bolt setting, reducing impact shock by 70%. Each unit is tested to 500,000 cycles with ISO VG 46 oil at 110°C, ensuring reliability in high-temperature stopes. Our global inventory supports 24-hour delivery with complimentary installation alignment tools and resin injection calibration kits.
