The Motion Index Drives RT Series Fixed Rotary Index Tables encompass a large range of sizes, ranging from our model RT100 up to our RT1250. In addition, special cam-driven devices can be custom made to order for your automation needs. RT Series Fixed Station Rotary Table are offered in a fixed number of stations or as a flexible turntable with a servo motor or standard AC brake motor with encoder. With the addition of Motion’s patented NANO Indexer Technology, the RT Series Fixed Station Rotary Table becomes the world’s most accurate barrel cam indexers.RT Series indexing tables are constructed with strength and reliability in mind. Robust design and components ensure this device will maintain precision in intense factory settings.
Among the many indexer manufacturers, what sets Pascal’s indexing table apart is undoubtedly its brakeless design, compact size, and durability. It has an ample amount of ports lending itself well to automation.
Pascal’s MDF index table operates with a 90° index 0.5 sec. Its unique rolling gear transmission is maintenance free and can operate with high index speed and accuracy for a long time unlike traditional worm gear. Traditional worm gear undergoes abrasive wear that can lead to backlash causing machining failure and degrading index accuracy.
Pascal’s high-performance rotary unions are integrated to enable clamp sensing and actuation but also provides a footprint 20% smaller than its competitors. Ideal for indexing large workpieces in compact machining centers, you will also achieve increased production capacity. As one example, our rotary indexing table can allow a machining center to increase their production capacity from 16 robodrill units to 24 units in the same amount of space.
The MDF index table has a total of 20 ports, lending itself well to automation. 18 of those ports can be used for hydraulic and air, while 2 are for coolant. A double acting cylinder with sensing can be used instead of a single cylinder, and its rotary joint accommodates a 7MPa pressure circuit.
Pascal is confident in the quality and reliability of our rotary indexers so much so that we use them in our own factories. That is also why these indexers are utilized in the factories of major automakers around the world.

The bearing used must ensure a jerk-free and shock-free motion sequence of the rotary tables for the respective applications as well as high repeatability and high positioning accuracy in the end positions. High payloads are moved.
The Franke bearing elements LEZ used are precisely matched to the various loads and thus guarantee the required jerk-free and shock-free movement of the turntables. Due to the four-point system, the bearings easily absorb the occurring loads.
The DGII Series is a line of of products that combine a high rigidity hollow rotary table with an AlphaStep closed loop stepper motor and driver package. It retains the ease of use of a stepper motor, while also allowing for highly accurate positioning of large inertia loads.
Our direct drive rotary tables provide high torque and are easy to integrate. They contain high-energy magnets in a simplified mechanical design and drive loads directly without the need for a transmission mechanism or gearbox. It allows customers to build them right into a drive system for flexible placement and integration with cooling pipes and cables, for example.
We supply a wide range of frameless motors, and our adjustable motors include an optical encoder, scale, bearing and housing. Given our selection, it can be challenging to choose the best direct drive motor for your project. Our engineers prefer to help you find the right rotary table for your requirements.
Our most popular rotary motor, the AXD series is characterized by a slim, compact "pancake" design with high peak and continuous torque despite the motor"s quite small form factor.Direct drive and brushless motor
The ACD series is a set of ironless rotary tables. This motor is cogging-free and features high-resolution optical encoder feedback and low speed variability. This permanent magnet motor is equally suited for either low or high speed applications.Zero cogging coreless motor
A popular question that we hear is, “How do I size a motor for my application?” This post looks at an example Rotary Index Table application and provides the equations and considerations needed to make the appropriate motor selection.
First, consider your machine’s movement. In our sample case of a Rotary Index Table, an engineer will need to first define all relevant information that will be used later in the Torque calculation. Typical information we will need includes:
Since we want to define the required motor torque, we want to be sure that we are using values that pertain directly to the motor itself. If there is a gearbox in the system, we need to be sure to reflect the required values back to the motor. We will need to determine the acceleration torque, deceleration torque, constant torque, and any torque due to gravity on the system. For this exercise, we will assume the index table is in a horizontal position, so the torque due to gravity will be zero.
Once we know the angular acceleration of the motor, we need to calculate the inertia of the load connected to the motor. In this case, we can approximate the index table inertia using the formula for a solid cylinder.
The load on the index table must also be taken into account. If the load is distributed evenly over the indexed surface, we can add this load into table weight to calculate the inertia of the complete system. If the load is not distributed evenly, then a separate load inertia will need to be determined, Jload.
Depending on the design of the system, there may be a constant friction torque, Mfriction, which must also be accounted for in the motor sizing. The amount of this constant torque will be dependent on the friction coefficient of the system and the weight of the table and load. Again, if there is a speed reduction in the system we can reflect this back to the motor shaft.
The A-688 direct drive rotary table with air bearings provides extremely high resolution and geometric performance. The angular resolution of this high precision air bearing spindle is 0.0015µrad (0.00003 arcsec), and flatness and eccentricity are specified better than 175nm and 300nm, respectively. This is made possible by high resolution, absolute measuring feedback encoders, and low-cogging frameless and slotless torque motors. The A-688 rotary table can be used in any orientation. Air bearing spindles guarantee a virtually unlimited service life with no wear, and zero required maintenance. As with all PI air bearings tables, the A-688 spindle is clean room compatible and requires no lubrication.
PI uses EtherCat based, high performance motion controllers ideally suited for closed-loop control of the rotation tables. Advanced algorithms are available to deal with changing load conditions and to suppress external disturbances.
