PDR210 Rotary Table from Primatics

Primatics PDR210 Rotary StageFor applications that require greater payload capacity without sacrificing angular accuracy, the Primatics PDR210C rotary table provides a high-performance direct-drive solution built for demanding industrial automation. As the largest model in the PDR series, the PDR210C combines precision motion, fast response times, and robust mechanical stability to support larger tooling, fixtures, and workpieces.

Designed for semiconductor, metrology, photonics, and laser-based systems, the PDR210C eliminates the backlash and wear limitations of traditional worm-driven rotary stages while delivering smooth, repeatable 360-degree positioning. Its oversized bearing platform and advanced servo design make it ideal for heavier-duty precision applications. 

Features

PDR210 Rotary Table Features

The PDR210C is purpose-built for engineers who need a larger rotary platform capable of handling heavier assemblies while maintaining high positional accuracy. With a 30 kg axial load rating, it supports more demanding applications where fixture size or payload mass exceeds smaller-stage capabilities.

Key Benefits:

  • Supports larger payloads without compromising precision
  • Oversized cross-roller bearing for improved rigidity
  • Maintains consistent rotational accuracy under load
  • Compact profile compared to traditional high-load rotary tables
  • Ideal for larger optical systems, wafer handling, and tooling platforms

The larger table diameter gives engineers greater flexibility when mounting oversized parts or integrating multiple process components.

The PDR210C offers increased load capacity, a larger mounting surface, and greater structural rigidity, making it better suited for larger tooling setups and heavier automation payloads while maintaining high precision.

Integrating precision motion into a machine should not add unnecessary complexity. The PDR210C is designed with practical integration features that simplify system design and improve serviceability.

Integration Features:

  • Single connector for motor, encoder, and home sensor
  • Hemisphere switch for fast homing
  • Large mounting surface for flexible fixture design
  • Clean mechanical layout for simplified installation
  • CAD models available for machine design planning

Its robust construction and simplified electrical architecture help reduce build time and improve long-term reliability in automated systems.

The PDR210C is designed for straightforward integration with simplified wiring, built-in homing, and CAD resources available for machine design, helping reduce engineering time during system development.

Configuration

PDR210 Rotary Table Configuration

At the center of the PDR210C is a high-efficiency neodymium brushless servo motor designed for rapid acceleration and low thermal output. Unlike geared systems, the motor drives the table directly, eliminating backlash and improving response time.

This direct-drive configuration allows:

  • Faster acceleration and deceleration
  • Shorter settling times between moves
  • Improved low-speed smoothness
  • Reduced heat generation
  • Higher repeatability over long production cycles

Its high pole-count motor design also improves low-speed control, making it valuable in precision inspection and laser machining environments.

The PDR210C improves machine cycle times because there are no mechanical gears to overcome. It accelerates faster and settles quicker after movement, reducing delays between process steps and improving machine throughput.

Accuracy

PDR210 Rotary Table Accuracy

The PDR210C uses a platen-mounted high-resolution glass scale encoder to provide precise angular feedback directly at the rotating surface. This minimizes error accumulation and improves motion consistency across the full rotation range.

Accuracy Highlights:

  • Resolution up to 0.18 arcseconds
  • Positioning accuracy within ±5 arcseconds
  • Full 360° continuous travel
  • Exceptional repeatability for high-precision processes

This encoder architecture makes the PDR210C an excellent fit for inspection, alignment, and calibration systems where rotational precision directly impacts process quality.

With sub-arcsecond resolution and ±5 arcsecond accuracy, the PDR210C is well-suited for metrology, machine vision alignment, and other precision-critical applications.

Q & A

PDR210 Rotary Table Q & A

+What is the maximum payload the PDR210C can support?
The PDR210C supports up to 30 kg axial load, making it the highest-capacity model in the PDR series and suitable for larger fixtures, tooling, and process assemblies.
+Why choose direct-drive over a geared rotary table?
Direct-drive systems remove backlash, reduce wear, and improve long-term accuracy because there are no mechanical transmission components between the motor and the rotary surface.
+Does the PDR210C support continuous rotation?
Yes. The PDR210C provides full 360-degree continuous travel, allowing unrestricted rotary positioning for scanning, inspection, and processing applications.
+What industries typically use the PDR210C?
The PDR210C is commonly used in semiconductor manufacturing, laser machining, precision metrology, photonics alignment, and advanced automation where high-load precision rotation is required.
+Can the PDR210C handle high-duty-cycle production environments?
Yes. Its oversized cross-roller bearing, direct-drive motor design, and low-wear architecture make it highly suitable for continuous-use automation systems.
