SMS R4 MUD- Tractor OMV Series Rotary Head Gearbox
Designed to be agile yet indestructible, the SMS III Super or Speed star Rotary Head is the preferred choice for operators who demand high-performance drilling using tractor-mounted system.
Integrated OMV Series Motor: The R4 is precision-engineered to utilize the OMV series motor, ensuring high torque efficiency and smooth hydraulic integration. This pairing provides the consistent rotation speed necessary for clean, fast boreholes.
Single-Piece Annealed Casting: While others use standard materials, our housing is a single-piece annealed casting. This heat-treatment process relieves internal stresses, making the gearbox resistant to the cracks and fractures caused by high-vibration drilling.
High-Flow Spindle Architecture: Featuring a 110mm spindle diameter and a 40mm flushing hole, the R4 ensures maximum air/water flow, facilitating rapid cuttings removal even at significant depths.
The SMS Signature: 1-Year Air Seal Guarantee
The biggest pain point in drilling is frequent seal failure. We solved this. The SMS III Super features our proprietary 1-Year Life Capacity Air Seals—a premium technology provided only by SMS Gears. This ensures your rig stays in the field, not in the repair shop, saving you significant maintenance costs and downtime.
