  • CPU-S

    Increased precision output bearing and flexible connectivity

    CPU-S

    The CPU Series Units are available in nine sizes with gear ratios of 30, 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 9 to 1840 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 CPU Series is available in three versions: the CPU-M Unit for direct mounting of any servo motor, the CPU-H Unit with hollow shaft to feed through supply lines for further drive systems and the CPU-S Unit with stainless steel input shaft enabling flexible integration into your design.

    If required, the Units are available as specific configurations tailored to your application, or with particularly high corrosion protection. The high capacity output bearing with maximum tilting rigidity and precision means that the Units can quickly and easily absorb high payloads and feature long service life. The Units are fully sealed and thus ideally suited for use in harsh ambient conditions. The Units accurate positioning guarantees stable machine characteristics with short cycle times guaranteed.
