Product Description

SMS R2- XL DTH Double Motor Rotary Head Gearbox

The SMS R2 XL DTH Double Motor is more than just a rotary head; it is the flagship gearbox that defined our brand. Known across the industry simply as the SMS XL, this powerhouse earned its reputation through relentless reliability in the most demanding waterwell drilling environments. When the job requires maximum torque and heavy-duty endurance, the XL is the only choice for truck-mounted rigs.

Single-Piece Annealed Casting: Unlike standard gearboxes, our housing undergoes a rigorous annealing process to eliminate internal stresses, ensuring the casing never cracks under the massive pressure of deep-well drilling.

120mm Heavy-Duty Spindle: Featuring a massive 120mm spindle diameter and a 45mm flushing hole, this unit is built to handle high-volume air and mud flow for rapid drilling progress.

1-Year Life Capacity for MUD Seals: A feature provided only by SMS Gears. Our specialized Swivel seals are engineered to last a full year, eliminating the frequent seal failures that plague other rotary heads and keep your rig in the field instead of the workshop.

Primary Applications:-

Inbuilt Water Swivel System: Optimized for Mud Pump drilling, instead of separate Water Swivel, thus cutting swivel cost.
Deep Waterwell Drilling: The preferred choice for heavy-duty truck-mounted rigs.
Large Diameter Boreholes: Optimized for high-torque, high-flow requirements.
