SVA / SVAL Series
630 – 1400 | 3,000 – 20,000 kW
Slide-bearing reduction gearboxes for the most demanding propulsion installations — SVA without clutch for CPP applications, SVAL with internal hydraulic multi-disc clutch for fixed-pitch propulsion in large commercial and naval vessels.
Slide-Bearing Power for the Most Demanding Vessels
White-metal slide bearings give the SVA / SVAL series the load capacity and service life required for the largest commercial and naval propulsion installations — from offshore support vessels to frigates and special-purpose ships.
White-Metal Slide Bearings
Hydrodynamic slide bearings handle the highest continuous loads with exceptional durability and low maintenance over decades of service.
SVA & SVAL Variants
SVA without clutch for controllable-pitch propellers; SVAL with an integrated hydraulic multi-disc clutch for fixed-pitch and disconnect capability.
Up to 44 kW/rpm
High torque density across the 630 - 1400 range, with two factory power variants (A / B) per size to match engine and propeller selection.
Continuous-Duty Construction
Fabricated steel housing, case-hardened tooth-flank-ground gears, pressure-fed lubrication, and integrated thrust bearing for unlimited-hours operation.

Specifications
SVA / SVAL Slide-Bearing Reduction Gearbox
| Model | Weight Dry | Standard Reduction Ratio | kW/rpm |
|---|
kW/rpm values are Continuous Duty ratings per the REINTJES Product Guide 2026, listed for each standard reduction ratio. Suffix A / B denotes the power variant (B = higher rating). SVA = reduction gearbox without clutch (CPP); SVAL = with internal hydraulic multi-disc clutch. Dry weights are taken from the REINTJES dimension tables for each gearbox size; entries marked “—” are listed “on request” or are configuration-dependent (e.g. SVAL clutch variants). Custom ratios and input speed variations available upon request.
