0509012129 Roller Bearing for Mining Hydraulic Rock Drill Rig

We engineer the Roller Bearing (Part No. 0509012129) exclusively for integration into Hydraulic Rock Drills—a critical component that ensures smooth rotational movement, minimizes friction, and enhances the overall operational durability of drilling equipment. We select high-grade alloy steel as the core material and apply advanced heat treatment technology during manufacturing, endowing the bearing with exceptional wear resistance, corrosion protection, and load-bearing capacity—even when it operates in the harsh conditions of mining, quarrying, and construction sites.

We maintain strict adherence to original equipment manufacturer (OEM) specifications during production, so the bearing guarantees seamless compatibility with leading Hydraulic Rock Drill models. It effectively reduces downtime and maintenance costs, as we design it to fit without modification and sustain long-term use. Whether you select it for equipment replacement or new assembly projects, we test the bearing against rigorous industry standards, and it delivers consistent performance through stable torque transmission and vibration reduction during continuous drilling operations.

We implement strict quality control measures throughout the production process and inspect each unit to meet the demands of heavy-duty rock drilling applications. Drill operators widely use this bearing in mining, quarrying, and construction projects where Hydraulic Rock Drills deploy, and they trust it for its ability to maximize equipment productivity while minimizing the risk of unexpected failures. As a key spare part for Hydraulic Rock Drills, it serves as a cost-effective solution to maintain operational efficiency in demanding work environments.
