GATE CDS Programmable Rotary Positioners: HTR and TCR Review: Specs, Price and Applications
CDS programmable rotary positioners use servo-controlled input to provide flexible angular motion. The current catalog distinguishes HTR tables from TCR positioners and from fixed-index cam tables. Generic servo-turntable listings do not identify a complete ordering configuration, so the actual series, size, motor input and mechanical drawing must be established before assigning ratings.
Quick Verdict
Consider the programmable families when station angles or index timing must vary under servo control. HTR and TCR are different mechanisms and load envelopes. A source image or broad “heavy-duty” description is not sufficient evidence that two assembled turntables share the same model or capacity.

Ordering boundary | Series, size, input gearbox/motor, load and complete assembly drawing |
Design and Engineering Assessment
Programmable station angles change the commanded sequence, while the mechanical ratio, torque and bearing limits remain fixed. Evaluate the full motion profile and settling at each required station. Servo control does not make every angle/time/load combination mechanically feasible.
HTR’s central opening can improve service routing, while TCR’s compact reduction architecture has a different installation envelope. Do not transfer HTR hole, bearing or gearbox data to TCR. The generic source listings should retain their own selected assembly identities when actual ordering drawings are available.
A freely programmed indexer differs from a fixed-dwell cam arrangement whose motion law is established mechanically. An axis described as “servo driven” can still use cam/reduction components. Compare the actual transmission architecture rather than assume it is a magnetic direct-drive table.
Resolve Model and Input Before Sizing
Specify HTR or TCR, size, servo input arrangement, ratio, load inertia and moments. Confirm motor flange/shaft compatibility and the separate motor/drive/safety scope.
Check whether external services limit rotation and whether the supplied assembly has an approved seal/environment configuration. A clean-looking nickel finish alone does not certify a complete cleanroom installation.
Accept the Programmed Process
Verify output scaling, reference, limits and clearances before loaded indexing. Measure reversal, station repeatability and warm-cycle settling at the fixture.
Preserve series, size, assembly drawing, motor/gearbox and controller program. A different input arrangement or similar housing requires renewed compatibility checks rather than being declared an identical spare.
Applications and Selection
Programmable rotary assembly, welding, packaging and process fixtures with an identified CDS servo-table configuration.
For GATE CDS Programmable Rotary Positioners: HTR and TCR, 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
Advantages
Programmable angular positioning
Different compact and central-opening architectures
Configurable servo-input arrangements
Limitations
Generic listing does not establish an exact model
HTR/TCR ratings cannot be combined
Transmission and bearing limits remain applicable
Who Should Consider GATE CDS Programmable Rotary Positioners: HTR and TCR?
Consider GATE CDS Programmable Rotary Positioners: HTR and TCR for programmable rotary assembly, welding, packaging and process fixtures with an identified CDS servo-table configuration. Establish the required operating point and installation interfaces before choosing the configuration, and use a representative loaded cycle as the acceptance basis.
GATE CDS Programmable Rotary Positioners: HTR and TCR FAQ
Are HTR and TCR the same table?
No. They have different mechanisms, sizes and installation/load scopes.
Are these necessarily magnetic direct drives?
No. Servo-controlled input can operate through cam or reduction components.
Does a generic source photo identify a full order code?
No. Obtain the actual assembly drawing and nameplate identity.
What TCR ratio is described?
The current family description identifies 72:1.
Does every family have the same center opening?
No. Use the selected HTR/TCR size drawing.
Does programmable positioning remove torque limits?
No. Motion profiles must fit the actual motor, transmission, bearings and load.
Can every servo motor be attached automatically?
No. Confirm flange, shaft, input loading and electrical compatibility.
What should acceptance measure?
Actual station accuracy/repeatability, settling, reversal and service routing with the final fixture.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
