  • CobaltLine®-CP

    Maximum torque capacity with precision output bearing

    CobaltLine®-CP


    CobaltLine®-CP 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 precision 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.

    The CobaltLine®-CP Series are supplied in three versions: the CPM Unit for direct attachment of any motor, the CPH Unit with hollow shaft to feed through supply lines or services for further axes and the CPS Unit with stainless steel input shaft enabling flexible integration into your design.

    The Units are available as specific configurations tailored to your application, or if required, with high corrosion protection. With a reinforced output bearing offering maximum tilting rigidity, they can easily absorb and accurately guide heavy payloads The Units are fully sealed and thus ideally suited for use in harsh ambient conditions.

    The CobaltLine®-CP Series can be used for ambient temperatures between -40 °C and 90 °C. The Units accurate positioning guarantees stable machine characteristics with short cycle times guaranteed.

  • CSG-2UH

    Increased torque range

    CSG-2UH


    CSG-2UH Series Units are available in ten sizes with gear ratios of 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 23 to 3419 Nm.

    The output bearing with high tilting rigidity enables the direct introduction of high payloads without further support and thus permits simple and space saving designs.

    Standard servo motors can be attached in a compact manner. The Units cover a wide torque range and feature long service life, confirmed by many years of successful service. Unit and motor together form a compact and lightweight system capable of quickly withstanding high loads. Due to the Units positioning accuracy, stable machine characteristics with short cycle times are guaranteed.

  • HFUC-2UH

    The standard series

    HFUC-2UH

    HFUC-2UH Series Units are available in thirteen sizes with gear ratios of 30, 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 9 to 9180 Nm.

    The output bearing with high tilting rigidity enables the direct introduction of high payloads without further support and thus permits simple and space saving design installations.

    If required, the Units are available as specific configurations tailored to your application and can utilise standard servo motors. Unit and motor together form a compact and lightweight system capable of withstanding high loads. On request, the series is available for ambient temperatures between -40 and 90 °C and can be used with a large selection of special lubricants tailored to your application. Due to the Units positioning accuracy, stable machine characteristics with short cycle times are guaranteed.

  • SHD-2SH

    Short overall length with largest hollow shaft

    SHD-2SH

    SHD Series Units are available in six sizes with gear ratios of 50, 100 and 160:1 offering repeatable peak torques from 12 to 453 Nm.

    The output bearing with high tilting rigidity enables the direct introduction of high payloads without further support and thus permits simple and space saving design installations.

    The SHD-2SH Simplicity Units are characterised by highly compact dimensions and low weight, consisting of the component set with shortened Flexspline and the high capacity output bearing. The absence of input and output flanges means maximum flexibility in design integration. The integrated hollow shaft can be used to feed through supply lines or services for further axes. The high capacity, integrated output bearing means that the Unit can quickly and easily withstand heavy payloads.
