Motorized worm gear driven rotary tables provide high angular resolution (the worm gear ratio directly multiplies the motor output torque and motor angle resolution) and holding torque. PI offers precision motorized worm gear rotary tables with both stepper motors and closed-loop servo motors with encoder feedback. While open-loop stepper motors are often used for their lower cost and ease of control, closed loop servo motors with encoder feedback provide higher speed, higher accuracy, and repeatability. PI also provides closed-loop stepper motor rotary stages, combining the best of both worlds. PI stepper motor rotation stages are provided with stepper motor controllers featuring a micro stepping mode for higher performance. For single axis applications, a compact and very cost effective single axis stepper motor controller is available.

For the best performance and highest velocity, direct-drive rotary stages with torque motors are recommended (link to new Rotary Stage Page with Direct Drive Torque Motors).

A Rotary Stage is a mechanical component of a motion system used to rotate an object in a single axis or plane of rotation.  The terms rotary stage or rotary table are often used interchangeably with rotary stage.  All rotary stages consist of a platform and a base, joined by some form of bearing or guide in such a way that the platform is restricted to rotation about a single axis or plane with respect to the base.  In common usage, the term rotary stage may or may not also include the mechanism by which the angular position of the platform is controlled relative to the base.

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.

Room in the Middle. ServoBelt Rotary stages offer two different through hole configurations. Available with 50-, 100- or 200-mm center openings, our large through hole stages accommodate large bundles of power, signal and pnuematic conductors. 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.

Direct Drive Performance. 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.

Robust, Lubed-for-Life Bearings. ServoBelt Rotary stages incorporate large full duplex, angular contact bearings, imparting moment and load capacities far in excess of its usual application requirements. This excess load capacity translates into virtually limitless bearing life.

Cost Effective. ServoBelt Rotary stages offer an economical solution for a variety of medium-duty rotary motion jobs such as driving carousel tables on packaging and assembly machines and providing fourth-axis rotary motion for laser cutting and mini CNC machines.

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.

Optional:  Cover plates, gearheads, EOT & Home switches, linear & rotary encoders, power-off electric brakes, motor wrap packages and versatile mounting brackets for multiple axis applications

GSN200-50K Servo Rotary Table offers an unparalleled combination of good accuracy and high load capacity. These rotary stages utilize a precision worm gear with the worm “flexed against the gear to ensure a proper mesh. This feature provides high repeatability with very smooth operation. Additionally, the rotary stages incorporate an oversized pre loaded cross roller bearing, offering exceptional stiffness and load capacity.

Control digital devices and make machinery more precise with a stepper motor from Alibaba.com"s wholesale equipment store. Our catalogue is the place to come when you need a replacement stepper motor rotary table or any other motor related products. You"ll find a huge array of wholesale motors, including step motors with high torque ratings that can offer incredibly precise control. Whether you"re constructing an astronomical telescope or a digital network for broadcasting, these motors will do the job.

Stepper motors are used in situations where devices need to be calibrated to extremely high levels of precision. They aren"t always the most powerful motors, but they do have very high torque levels, and this allows them to control devices in ways that other motors cannot. And they also tend to work well with digital devices due to their "step" mechanism. For instance, you can find step motors in many hard drives, handling millions of operations every minute. They have also become a go-to motor style for robotics installations. So you might need one for an advanced production line. When you need a stepper motor rotary table, finding the right motor is easy. Just search Alibaba.com"s catalogue and you"ll easily find what"s required.

We designed this tilting angle table with a stepper motor as a way to offer a cheaper and quicker rotary axis for laser engraving instead of using our CNC rotary table. We have drilled and tapped the table top plate to accept one of our NEMA 23 stepper motors. You can mount any NEMA 23 frame stepper motor or servo motor to the table.* In addition to the stepper motor, we designed a chuck adapter for our 3- and 4-jaw self-centering chucks. This combination offers you a way to hold and rotate your parts.
