VA Series
2451 – 4855 | 1,830 – 13,164 kW
High-power reduction gearboxes without clutch — engineered for controllable-pitch propeller (CPP) applications and large diesel-mechanical propulsion in commercial workboats, dredgers, and offshore vessels.
Engineered for Controllable-Pitch Propulsion
The REINTJES VA series delivers up to 13,000 kW of high-torque reduction in a clutchless single-reduction package — the REINTJES standard for CPP-driven workboats, dredgers, and offshore vessels.
CPP-Optimized Design
Reduction gearbox without clutch — engineered for controllable-pitch propellers where reverse thrust is handled by propeller pitch, not the gearbox.
High Torque Density
Up to 13,164 kW continuous duty at 1,200 rpm in the VA 4855 — helical gears, case-hardened and tooth-flank ground, fabricated steel housing.
Two Standard Ratios per Model
Each VA model is published with two factory-standard reduction ratios — matching propeller selection to engine characteristics without custom tooling.
Continuous-Duty Reliability
Pressure-fed lubrication, integrated propeller thrust bearing, and seawater-resistant heat exchanger built for unlimited-hours commercial operation.
