CobaltLine®-2UH

Maximum torque capacity with extended temperature range


CobaltLine®-2UH Series Units are available in six sizes with gear ratios of 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 23 to 841 Nm.

The output bearing with high tilting capacity often allows direct attachment of heavy payloads without the need for further support, thereby providing simple and space saving design installations.

They cover a wide torque range and feature long service life. If required, the Units are available as specific configurations tailored to your application. Standard servo motors can be attached in a compact manner. The CobaltLine® Series can be used for ambient temperatures between -40 °C and 90 °C.
