SMS FT1- Compact OMS Double Motor Rotary Head Gearbox

SMS FT1 Compact OMS Series:

Heavy-Duty Spindle in a Compact Frame While most light-duty gearboxes compromise on internal support, the SMS FT1 features our signature 4-bearing main spindle arrangement. This ensures the spindle remains perfectly aligned even under high radial loads, significantly reducing wear and extending the life of your hydraulic motor.

Optimized for OMS Series: Specifically designed to integrate seamlessly with Danfoss OMS Series motors, allowing for a perfect match of torque and RPM for waterwell applications.

Single-Piece Annealed Casting: The housing is crafted from a single-piece annealed casting. This heat-treatment process removes internal stresses, providing a housing that is far more durable than standard welded or non-annealed alternatives.

Spindle Dimensions: A robust 100mm spindle diameter paired with a 40mm flushing hole ensures high-volume air and water bypass, keeping your bit cool and your hole clean.

Versatile Mounting Options The FT1’s compact design makes it the "go-to" gearbox for:

Tractor-Mounted Rigs: Ideal for rural waterwell drilling where maneuverability is key.

Crawler Rigs: Perfect for geotechnical exploration or mining support where a lightweight, stable rotary head is required.
