Geislinger Carbotorq®

The Carbotorq® is a lightweight maintenance-free elastomer coupling. It is designed to minimize reaction forces and bearing loads. Its innovative design provides torsional elasticity and misalignment capacities. The torsional elastic component is bonded between fibre composite membranes which provide elasticity and high internal damping properties.

With its low weight and minimized reaction force, the Geislinger Carbotorq® significantly reduces the bearing loads, and thus, increases system service life. Available with torques up to 10kNm, the requirements for leisure craft boats, crew vessels, work boats, and tug boats are well met. The integral design provides constant misalignment values under all circumstances.

The Geislinger Carbotorq® uses silicone elastomer and, unlike other couplings, uniquely combines the misalignment function and the torsional elasticity. This is achieved by connecting the elastomer to a pair of corrugated composite membranes.

In applications where weight is a concern, Geislinger products can be combined to a Shaftline. This lightweight Shaftline combination often consists of a Carbotorq®, a Geislinger Gesilco® Shaft, and other couplings in our Gesilco® product range. This provides a very light-weight drive train with extremely high misalignment capabilities. The composite materials also provide high internal damping for high-frequency vibrations.
