Rotary axis RDH-S
Discover the precise Rotary axis RDH-S, developed for demanding automation applications. This first-class component is characterised by its impressive transmission accuracy of less than 1.5 arcmin and offers outstanding repeatability of less than ±6 arcsec.
The RDH-S is available with a reduction ratio of 1:50 or 1:100 and has a powerful servo motor that ensures optimum performance and control. Thanks to its IP 65 protection rating, it is optimally protected against dust and water, making it ideal for use in demanding environments.
Another highlight of this Rotary axis is the hollow shaft design, which enables flexible installation options. The maintenance-free design ensures a long service life and reliable operation without additional maintenance costs.
Equipped with a precision gearbox, the RDH-S offers a heavy-duty and rigid output bearing as well as zero backlash and high torsional rigidity. These features make it the perfect choice for applications where maximum precision and reliability are required.
