Centa Centaflex M-160 Flexible Propeller Shaft Coupling for Marine Gearboxes up to 500 Nm

The Centa Centaflex M-160 Flexible Propeller Shaft Coupling is an elastic marine coupling designed to transmit torque between the gearbox output flange and propeller shaft while absorbing vibrations and reducing the transmission of noise and thrust loads.

Its large rubber element provides flexible power transmission and contributes to a reduction in vibration-related noise of approximately 5 dB(A). The coupling incorporates a mechanical safety connection that maintains torque transmission even if the rubber element completely fails.

The Centaflex M-160 also provides electrical isolation between connected components, helping protect the propulsion system against electrolysis. It is designed for a maximum rotational speed of 3500 RPM and permits angular misalignment up to 2°.

The M-160 series offers different mounting configurations for selected Technodrive, ZF, Volvo, Yanmar, Kanzaki, Paragon, Bukh and Farymann marine gearboxes.

Propeller Shaft Clamping Hubs

The Centaflex M-160 coupling requires a separate clamping hub to connect it to the propeller shaft. The correct hub must be selected according to the shaft diameter and ordered separately.

Standard clamping hub bore sizes:

25 mm
30 mm
35 mm
40 mm
1"
1 1/4"
1 1/2"

The shaft clamping hub uses the 9088002Kxx article number format, where the suffix identifies the required shaft diameter.

For example, a Centaflex M-160 coupling for a Technodrive gearbox with a 30 mm propeller shaft requires coupling article 9088002 and clamping hub 9088002K30.

Installation and Selection

The Centaflex M-160 coupling must be selected according to the gearbox model, output flange mounting dimensions and propeller shaft diameter.

D: Centering diameter in mm
M: Mounting thread size
Tk: Bolt circle diameter in mm
Z: Mounting hole quantity and angular arrangement
TA: Tightening torque in Nm
Shaft Diameter: Bore size of the separately ordered clamping hub

The rated coupling torque must be suitable for the gearbox output torque. The selected mounting configuration must match the corresponding gearbox flange.

When ordering, specify the gearbox brand and model, output flange dimensions, mounting hole pattern, centering diameter and propeller shaft diameter.
