A Rotary Stage is a key mechanical element in a motion system, primarily designed to facilitate the rotation of an object along a singular axis or plane of rotation. The terms 'rotary stage' and 'rotary table' are frequently used interchangeably due to their shared functionality.
Every rotary stage features a platform and a base, which are interconnected by a type of bearing or guide. This connection design specifically ensures that the platform is limited to rotation along a singular axis or plane concerning the base. The platform's angular position is regulated relative to the base by a control mechanism. However, the term 'rotary stage' may not always denote this control mechanism's inclusion in everyday usage.
ServoBelt Rotary Stages from Bell Everman are compact, high-torque rotary stages that offer through hole size and speed comparable to direct-drive rotary tables costing thousands more. ServoBelt Rotary stages offer two different through hole configurations. Available with 50-, 100- or 200-mm center openings. They also make it easy to integrate laser and optical systems. Standard-sized models with 16- or 25-mm through holes offer a more economical choice when fewer utilities need to pass through the center of the stage. Designed for NEMA 23 and 34 motors, the ServoBelt rotary stages offer speeds up to 1,000 rpm, continuous torque to 6.6 N-m and resolution down to 0.16 arc-sec with Renishaw ring encoders or tape scales for partial rotation.
The 300 & 400 Series Rotary Stages from Lintech are known for their versatility and adaptability. They come with a variety of features that can be customized to meet specific application needs. One notable characteristic is the availability of optional components. These include cover plates, gearheads, end-of-travel (EOT) and Home switches, linear and rotary encoders, power-off electric brakes, motor wrap packages, and versatile mounting brackets designed for multi-axis applications.
Moreover, Lintech Rotary Stages offer a diverse selection of gear ratio options to suit various operational demands. The adaptability extends to motor compatibility as well, with a variety of NEMA and metric motor mounts and couplings available to facilitate integration into a wide range of system configurations. This combination of features contributes to making Lintech Rotary Stages a flexible solution for numerous motion control applications.
Each offers precision performance and design flexibility for use in a wide variety of Motion Control applications, including:

The 300 Series tables feature a rigid pair of quality angular contact bearings which produce smooth table top rotation. The low backlash precision worm gear drive provides exceptional accuracy and repeatability. All aluminum components have a black anodized finish and each table can have either a NEMA 23 or 34 motor mount attached. Threaded steel inserts in the table top provide for easy mounting of the user load while the 0.75 inch (19 mm) through hole provides easy access from below. |

The 400 Series tables feature a rigid pair of 4 point contact radial ball bearings which produce smooth table top rotation. The low backlash precision bronze and steel worm gear drive provide years of high accuracy and superb repeatability. This rugged construction offers load capacities of 1000 pounds (453 kgf) and moment loads of 225 ft-lbs (305 N-m). The NEMA 34 motor mount and bushing can be positioned radially 360 degrees for convenient motor location. The large 4.5 inch (114 mm) through hole provides easy access from below. |
