Zero-Backlash Servo Rotary Indexing Table from Sankyo Automation

The Sankyo Automation RollerDrive® Reducer is a precision gear reducer that uses a zero backlash roller gear mechanism. The unit is constructed from an input shaft and a turret (output shaft) that is assembled with roller followers. The roller followers are preloaded against a screw-like input shaft to eliminate backlash.High Speed Indexer

Sankyo servo indexing tables offer a constant lead cam with a servo motor drive for programmable motion. Sankyo servo indexing tables provide fast highly accurate motion, with the added capability to move medium to heavy loads. The preloaded cam & turret provides a high performance zero-backlash servo indexing table for all your automation needs.

The RU Series servo indexing table is available in 11 different sizes. These servo indexing tables come with varying ratios to maximize the motor’s torque capacity, speed requirements and enhance the overall accuracy. Special applications may require double reduction ratio of the internal cam and an additional reducer to provide large torque capacities or slower speed.

Features include:

  • Zero-Backlash -The RollerDrive uses a unique preloaded mechanism to completely eliminate backlash and deliver output motions that are faithfully true to input commands
  • Design -RollerDrive technology incorporates a cam with a high gear reduction to deliver large torque capacities with smaller servo motors
  • Second Reducer Option -Multiple reducer options keep the servo at optimal RPM speed
  • Rigidity Suitable for Machining Applications -An exclusive ouput turret bearing and cast-iron housing toleratres heavy vibrations associated with machine tool applications
  • Versatile for Retooling -RU Series can keep pace with the ever-changing tooling requirements
  • Short settling times – The RollerDrive provides fast highly accurate dynamic motion

Custom Rotary Positioning Stages from Bell Everman

A guide to ServoBelt Rotary and Direct Drive Theta modification

While off-the-shelf rotary stages will do the job in most cases, sometimes your application requirements call for a customized stage.  It may be something as simple as a special bolt hole pattern on the top of the stage.  Or you may need a way to secure a workpiece in the stage center opening.  Or you may need to squeeze a rotary positioning device into a tight space.

Whatever your requirements, we can help.  We’ve introduced accessories and modular design features that make it easy to customize our standard Servo-Belt Rotary (SBR) and Direct Drive Theta (DDT) rotary stages. And in cases where our standard rotary platforms can’t be modified to fit your requirements, we can often design and build one-of-a-kind rotary motion systems to your specifications.

A Full Family of Rotary Stages

Bell Everman Rotary Stage Family

Bell Everman Rotary Stage Family

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.

Rotary Stages use a precision machined worm gear assembly and either ball, cross roller, or angular contact bearings to support the table top load.  The selection of different gear ratios allow for either high resolution or high speed in a low profile package.  The use of any step motor or servo motor system to drive rotary tables is a key advantage since it allows the use of a preferred motion control system.

Choosing the Right Rotary Table

At Lintech, we know that sometimes it can be hard for our customers to choose the right tool for the right job.  With so many choices out there, once you find the right part it can be hard to decide which model is perfect for you.  That’s why you go to an expert – or in this case, you let the expertise come to you.  This time around, we thought we would outline a few critical things you should be looking for in a rotary table.

For those not “in the know”, a rotary table is a precision metalworking positioning device used mostly by the automotive, semiconductors, and packaging industries.  To get to know what you need, we think it’s best to go over Lintech’s 2 distinct models: the 300 and the 400.

Rotary Table - 300

  • The 300 series is used for general automation, the kind of automation that demands decent accuracy and repeatability.   We like to use the example of a robot filling an aspirin bottle. The task does not demand super-fine positioning, but does demand versatility in positioning speeds and locations. Therefore, our 300 series is perfect because it is accurate without all the extra bells and whistles you may not need.  This also makes it our most affordable rotary table.

Rotary Table - 400

  • Of course if you need larger load capacity AND great accuracy, then it would be cost-effective to use our 400 series.  Not only can the 400 handle loads up to 1000 pounds, but it also has large thru-hole tooling.  Therefore, it is easier to maintain, offers amazing repeatability, and most importantly, it’s as tough as nails.  We really haven’t had a single one of these table returned to us in over 20 years!

In the end, you should base your choice on the kind of work you need the rotary table to do. Lintech’s 300 is a cost-effective way to handle smaller loads while the 400 is the perfect fit for your bigger jobs.  Whichever you choose, you will get the amazing accuracy, versatility, and toughness that everything we make at Lintech offers.
