This series of hydraulic motors are original factory compatible and replacement hydraulic motors designed specifically for Atlas Copco and Epiroc production-type drilling rigs, with part numbers 3115350783, 3115350782, and 3115350781 respectively. As the core executive components of the drilling rig's hydraulic system, these motors are responsible for converting hydraulic energy into mechanical energy, driving the rotation, feeding, and auxiliary mechanisms of the drilling module, ensuring high-precision, high-reliability continuous operation in deep hole drilling, mining, and heavy engineering construction.

Among them, 3115350783 corresponds to the MSS 250 06 model cycloidal motor, which adopts a mature cycloidal rotor pair design, featuring a compact structure, low speed, and high torque, and is particularly suitable for the positioning and auxiliary actions of the drilling rig.

1. Optimized specifically for drilling rig working conditions
• High impact load bearing capacity: Aiming at the frequent impact loads and vibration conditions in drilling operations, the internal kinematic pairs have undergone strengthening treatment, and the surface hardness of key friction pairs is high, with resistance to fatigue and micro-cracks.
• Continuous heavy-load operation: Adopting a reinforced bearing and housing design, it can work continuously and stably under high-load cycles and high oil temperature environments, meeting the long-term continuous operation requirements of drilling rigs.

2. Robust and Durable Design
• High-strength casing: Made of high-quality cast iron or alloy steel, it has excellent corrosion resistance and wear resistance, suitable for harsh working environments such as mines and tunnels.
• Dust-proof sealing: Equipped with heavy-duty multi-lip shaft seals, which can effectively prevent drill cuttings and dust from entering the motor, extending the service life.
• High-pressure resistant structure: The optimized design of internal flow channels can withstand the high-pressure impact of the drilling rig's hydraulic system, ensuring stable power transmission.
3. High-precision Power Output
• Stable low-speed torque: It can output stable torque even at extremely low speeds, meeting the needs of fine operations such as drill pipe alignment and precise feeding.
• High-efficiency energy conversion: The optimized flow distribution mechanism reduces internal leakage, improves system efficiency, and reduces fuel consumption and heat generation.

* Continuous pressure :Max. value of operating motor continuously.

* Intermittent pressure :Max. value of operating motor in 6 seconds per minute.

* Peak pressure:Max. value of operating motor in 0.6 second per minute.
