The RTC series of rotating tables from Meccanica Besnatese are compact, precise
and versatile. There are currently two sizes available: RTC 90 and RTC 120.
The rotational movement is realized by means of a worm screw system - a helical
gear wheel, with 360° continuous rotation with high precision and repeatability.
Two positioning systems can be set up with the same base module:
manual control: with position reading via digital position readout
motorized control: by means of a special made-to-measure interface, it is possible
to apply step motors or DC servomotors of different manufacturers and sizes.
