This Cylinder Block (Part No. 86778453) is a precision-machined core component that engineers design exclusively for hydraulic rock drills—the workhorses of mining, quarrying, and underground construction projects. We craft it from high-grade alloy steel and adopt CNC machining technology to ensure tight tolerances and seamless compatibility with leading hydraulic rock drill models. Unlike generic alternatives, we build this cylinder block to withstand extreme operating conditions, including high hydraulic pressure, constant vibration, and abrasive rock debris, making it a critical part that maintains uninterrupted drilling operations.
The cylinder block acts as the central hub for hydraulic power distribution in rock drills and controls the movement of pistons and drill bits with exceptional accuracy. Our 86778453 model features a corrosion-resistant coating that extends service life by up to 30% compared to uncoated parts, while its reinforced internal structure minimizes wear and tear even during prolonged use. Additionally, we design the part for easy installation—no specialized tools required—which reduces equipment downtime and labor costs for your team. Whether you’re drilling blast holes in open-pit mines or creating tunnels underground, this cylinder block delivers consistent performance that keeps your hydraulic rock drills running at peak efficiency.
We understand that compatibility is a top priority for mining and construction professionals, which is why we test the 86778453 cylinder block to meet or exceed OEM specifications for hydraulic rock drills. It fits a wide range of popular models, which eliminates the hassle of cross-referencing part numbers or modifying equipment to fit aftermarket components. Our quality control process includes rigorous pressure testing, dimensional inspection, and wear resistance trials, which ensures every cylinder block that leaves our facility is free from defects and ready to perform in the field. For businesses that rely on hydraulic rock drills for daily operations, this part is a cost-effective, reliable solution that replaces worn or damaged cylinder blocks.
When it comes to hydraulic rock drill spare parts, durability and performance are non-negotiable. Our 86778453 cylinder block offers a perfect balance of strength, precision, and value, which helps you reduce maintenance costs and maximize equipment uptime. We also offer customizable solutions, including tailored coatings and dimensions, that meet the unique needs of your drilling projects.
