Hydraulic Locking Piston (Part No. 86747110) is a high-precision, heavy-duty wear-resistant spare part exclusively engineered and manufactured for hydraulic rock drills—the indispensable core equipment in mining, quarrying, rock excavation, and tunneling projects. Tailored to match the hydraulic system specifications of mainstream hydraulic rock drill models, this piston is a direct replacement part that eliminates the need for on-site modification, saving precious installation time for mining and construction teams. As a critical component in the drill’s hydraulic control system, it is responsible for accurate stop-and-lock operations, which directly affects the stability and safety of the entire rock drilling process.
Crafted from premium high-strength alloy steel with a specialized heat treatment process, the 86747110 hydraulic stop piston boasts exceptional pressure resistance, wear resistance, and corrosion resistance. It can withstand extreme working conditions such as high-pressure hydraulic impact, continuous vibration, and abrasive dust erosion in mining environments, far exceeding the service life of ordinary piston parts. The piston’s surface is precision-machined with a tolerance of ±0.01mm, ensuring a tight seal with the hydraulic cylinder and minimizing friction loss during operation. This not only reduces the risk of hydraulic oil leakage but also optimizes the energy efficiency of the hydraulic rock drill, lowering overall operational costs for enterprises.
Whether you are replacing worn-out piston parts for hydraulic rock drills in open-pit mines, underground tunneling projects, or quarrying sites, the 86747110 hydraulic stop piston delivers consistent and reliable performance. It is compatible with a wide range of hydraulic rock drill brands and models, making it a versatile spare part choice for equipment maintenance teams and mining contractors. By choosing this high-quality piston, you can significantly reduce equipment downtime caused by component failure, improve the continuous operation rate of hydraulic rock drills, and enhance the overall productivity of mining and excavation projects. Additionally, our product complies with international industry standards, with complete quality inspection reports and traceability codes, ensuring that every piston delivered to customers meets strict quality requirements.
