Motion Index Drives TSR Rotary Indexing Ring Tables Review: Specs, Price and Applications
TSR is Motion Index Drives’ open-center ring-indexing table family for layouts that need substantial central access. It can be supplied as a fixed-station cam indexer or a flexible positioning assembly using a suitable constant-lead cam and controlled motor. Those are different motion architectures, not interchangeable operating modes of every supplied table.
Quick Verdict
Consider TSR when central tooling, robot access or product transfer genuinely requires a ring arrangement. Size the exact model from tooling inertia, process loads, index time and the selected drive. Resolve the manufacturer’s web-versus-brochure specification differences on the approved project drawing before relying on a load or accuracy figure.

Design and Engineering Assessment
The open center is TSR’s defining layout benefit. It can preserve space for stationary equipment or a transfer path within the rotating tooling. It does not automatically reduce the tooling’s mass moment of inertia; a large ring or workpiece located far from the axis can make acceleration demands substantial.
Fixed and flexible cam arrangements should be selected deliberately. A fixed design mechanically defines the required index and dwell relationship. A flexible constant-lead arrangement relies on the specified motor, feedback and control to program motion. Changing the control program does not turn an arbitrary fixed cam into a flexible one.
The manufacturer’s TSR1000 web and brochure entries differ materially. The web table lists ±8.25 arcseconds and 1455 kN axial force; the Ring-Series load table lists ±20 arcseconds and 1130 kN. This review does not select the more favorable figure or combine either with another revision’s dimensions. Require the exact approved specification.
Linear positioning error depends on radius as well as angular error. As an illustrative small-angle calculation,20 arcseconds at a 1 m radius corresponds to roughly 0.097 mm of tangential displacement. That is not a measured TSR result. State the process radius and acceptance reference when converting between angular and linear requirements.
Open-Center Layout and Tooling Support
Model the stationary equipment, rotating tooling, workpiece envelope and access path together. Include cable, air and other service routing where it crosses or approaches the rotating structure. An open center provides space rather than automatically supplying a rotary utility interface.
Confirm the full table, drive and tooling envelope on the project drawing. A tooling-diameter capability is an engineered option, not approval of every plate thickness, overhung load or center-of-gravity position at that diameter.
Load Combination, Inertia and Step Time
Evaluate axial force, radial force, tilting moment and mass moment of inertia as separate quantities. A bearing load figure is not a payload in kilograms, and a static load rating is not a dynamic index-time guarantee.
Use the exact model’s inertia and step-time table with the intended number of stops and motion law. Include fixtures and workpieces in the inertia model. The motor and drive must also meet the actual repeated duty and stopping requirements of the machine.
Fixed Cam Versus Flexible Positioning
Choose fixed indexing for a stable motion sequence whose stations and dwell can be defined mechanically. Coordinate the process timing with the actual cam design rather than assuming every input revolution produces arbitrary output motion.
Choose a flexible configuration when index angles, speed profiles or synchronization must be programmable. Identify the constant-lead cam, motor, encoder and controller scope. The complete feedback and control arrangement determines the positioning behavior of that supplied system.
Resolve Specification Versions Before Purchase
Keep the web-versus-brochure TSR1000 differences visible in the technical inquiry. Request an approved drawing and load/accuracy data for the exact construction and revision. An unexplained larger load or smaller accuracy number should not become the basis for tooling release.
Define whether acceptance concerns angular indexing accuracy, repeatability, runout or workpiece position at a specified radius. These are different measurements. A catalog linear figure without its reference diameter does not establish accuracy at every process location.
Commissioning and Installed Value
Verify installation alignment, tooling clearance, drive configuration and the complete process sequence. Test representative loaded indexing, settling and synchronization. Validate the machine’s guarding, stopping and restart design for the actual rotating mass and tooling.
Compare TSR with a smaller conventional rotary table when central access is optional. When the ring is necessary, compare complete support structure, drive, tooling, utilities and service scope at the same duty. Obtain configuration-specific commercial terms rather than treating a broad family overview as a supplied system quotation.
Applications and Selection
Large open-center rotary positioning with stationary tooling or equipment inside the ring
For Motion Index Drives TSR Rotary Indexing Ring Tables, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Price: Request a quote for the exact configuration. Compare the product, compatible control equipment, required mechanical parts, cabling and commissioning as one installed system. A component price alone does not represent the cost of a working automation axis.
Evaluate an alternative against the same duty and acceptance criteria. Match the continuous operating requirement first, then compare transient capability, feedback, mechanical fit and support. This avoids choosing between superficially similar products whose ratings describe different operating conditions.
Pros and Cons

Motion Index Drives TSR Rotary Indexing Ring Tables FAQ
Why choose a ring table?
Choose it when the machine benefits materially from central access for tooling, stationary equipment or transfer. A conventional table may be simpler when that opening is unnecessary.
Can every fixed TSR become programmable through software?
No. Flexible positioning requires the specified constant-lead cam, motor, feedback and control architecture.
Which TSR1000 accuracy figure is guaranteed here?
No universal figure is guaranteed. The web and brochure differ; obtain the exact approved construction and acceptance specification.
Can the web axial load be combined with brochure dimensions?
Do not assume that. Resolve the model and revision and use a consistent approved set of dimensions and load conditions.
Is an axial force rating a payload in kilograms?
No. Evaluate the actual forces, moments, inertia and dynamic duty with the supplier.
Does a large tooling diameter establish a fast index time?
No. Tooling mass distribution, inertia, motion law and drive selection determine the dynamic requirement.
Are angular and linear accuracy interchangeable?
They require a defined radius and measurement reference. State the process location and distinguish accuracy, repeatability and runout.
What should be sent for sizing?
Provide model objective, open-center need, tooling geometry, mass and inertia, load combinations, index and dwell requirements, drive/control scope, environment and acceptance criteria.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
