Spiroflex KS/KJ

Highly elastic shaft couplings for torque of up to 928 kNm. The highly torsionally elastic SPIROFLEX shaft coupling compensates radial, axial and angular alignment deviations, by virtue of its elastic rubber elements. Its high torsional elasticity and excellent dampening capability renders this coupling indispensable for propulsion systems prone to torsional vibration.

Pneumaflex KA

Highly elastic clutches for torque of up to 304 kNm. Pneumatically switchable. The special qualities of a highly torsionally elastic and vibration dampening coupling and those of a pneumatically operated double cone friction clutch are purposefully combined in this PNEUMAFLEX clutch. It reliably interrupts or establishes the flow of power between the diesel engine and the other driving components.

Pneumastar KU

Torsionally stiff clutches for torques of up to 1400 kNm. Pneumatically switchable. For stiff, but switchable connections. The PNEUMASTAR clutch is a torsionally stiff double-cone friction clutch. The clutching components consist of two inner and two outer friction cones of which the inner ones are pneumatically pressed against the outer tapered friction faces via a clutching cylinder operated pneumatically. Rubber sleeve springs form the torsionally stiff portion of the clutch.


Gear couplings formally branded as Lohmann + Stolterfoht, designed with crowned teeth and are used where torques must be transmitted through shafts that are subject to movement in all axis’s. The gear couplings can compensate angular, radial and axial misalignments. For marine applications such as generators, (dredge/jet) pumps, cutter drive shafts and other shaft-to-shaft connections. 


RADILUS®️ LRL – Bearing with top and bottom shells
RADILUS®️ LRF – Bearing with top and bottom shells, plus plain sliding surfaces on ends of shells to absorb minor axial forces
RADILUS®️ LRH – Bearing with bottom shell only
Bearing formally branded as Lohmann + Stolterfoht with self lubrication by fixed oil ring which is immersed in the oil sump. Are designedwith external lubrication used in cases where heat dissipation via the housing surface and through the fitted cooler are insufficient. The size of the bearing is governed by the shaft diameter, which in turn depends on the torque to be transmitted or on the regulations of the classification societies.


AXILUS®️ LA..W – Self-lubricating and provided with built-in tube cooler, sizes 13 – 50
AXILUS®️ LA..Z – Prepared for external lubrication, sizes 13 – 85
AXILUS®️ LA..N – Self-lubricating bearings
AXILUS®️ LAK – Thrust Bearings with Shaft Disconnecting Device
Thrust Bearings with Shaft Disconnecting Device formally branded as Lohmann + Stolterfoht, are primarily used in shipbuilding to absorb the propeller thrust. Moreover, it enables the power flow from engine to propeller to be interrupted. For this purpose the bearing has been fitted with a pneumatically clutchable gear coupling which can be engaged or disengaged at standstill. Disconnecting the shaft from the engine in this manner offers many advantages for the conomical and safe running of a ship. The thrust bearing has been fitted with a pressure lubrication system which ensures optimum lubrication and dissipation of heat.


Marine Gearboxes formally branded as Lohmann + Stolterfoht, are custom solutions for maritime applications, helps a ship’s main engine to operate over long periods at the most efficient operating point possible.
Available as twin-/multiple-drive and single-drive reduction gearboxes, Propeller outputs of up to 50 MW, Single-stage and multistage solutions, Low-vibration and noise-optimized.
For marine applications such as generators, (dredge/jet) pumps, cutter drive shafts and other shaft-to-shaft connections.
