Naval & Government Vessels
250 – 30,000 kW
The Army, Army Corps of Engineers, Department of Transportation, and other government agencies require proven and reliable power train solutions to operate effectively, even under extreme environment conditions. REINTJES gearboxes deliver mission-ready performance with shock-rated, robust designs.
Mission-Ready, Built to Class
REINTJES naval and governmental gearboxes are engineered for the most demanding service — shock-resistant, robust reliability, and certified to the major classification societies, from patrol craft to frigates and support vessels.
Shock-Resistant & Robust Reliability
Shock-rated execution, resilient mounting, watertight sealing and degaussing reduce acoustic and magnetic signatures.
Certified to Class
Supervision and approval to all major classification societies (IACS), with documentation to international IETM standards.
Proven Disc-Clutch Drive
Built-in hydraulic disc clutches with smooth, adapted-pressure engagement and full power in both senses of rotation.
Customised for the Mission
Steel, cast-iron or aluminium housings, double-helical toothing, PTO/PTI, turn drive, shaft locking and more — tailored per project.

Browse by Housing Material
Fast-vessel gearboxes are built in weight-saving aluminum alloy; workboat gearboxes come in grey cast iron or fabricated steel for maximum strength.
Buy America Compliant
Karl Senner offers Buy America–compliant REINTJES gearboxes for federally funded programs — independently validated for FTA Buy America, the Build America, Buy America Act, and Defense Security Cooperation Agency guidelines.
Turn Drive
The turn drive allows turning the propeller shaft even when the main engine is standing still, e.g. for maintenance work.
- Operation with a control panel and with a remote control
- Current status can be monitored and visualised with the LOP
Double Helical Toothing
Oil Pre-Heater
The oil pre-heater heats up the oil to a temperature of >25 °C.
- Manual and automatic operation are both possible
- Current status can be monitored and visualised with the LOP
Local Operating Panel (LOP)
The LOP can be used for various purposes including:
- Control of the clutch(es)
- Control of electric oil pumps
- Monitoring alarms, operating conditions, pressure, speed and other values
- Operation of turn drive, shaft locking device and oil pre-heater
The LOP control cabinet comes with a TFT display with a customised menu structure.
Shaft Locking Device
With the shaft locking device the propeller shaft can be mechanically locked and therefore be secured in its position.
- Spring-loaded
- Easy-to-operate
- Current status can be monitored and visualised with the LOP
Resilient Mounting of Gearbox and Accessories
Proven Across the Fleet
REINTJES naval and government gearboxes bring shock-rated, robust reliability to defense and agency fleets — from patrol craft and corvettes to Coast Guard lifeboats.
