Servo Motor Hollow Rotary Table (HRT350 Series)
The Hansheng HRT350JS-L2 Hollow Rotary Table is a high-precision servo gearbox designed for heavy-duty automation applications. It combines the high torque and rigidity of a cam indexer with the flexibility and accuracy of a DD (Direct Drive) motor. Featuring a large hollow bore, this rotary actuator allows for easy routing of cables and pneumatic pipes, making it the ideal solution for complex 4th-axis motion control and rotating platforms.
Compatible with major servo motor brands (e.g., Panasonic, Yaskawa, Mitsubishi, Delta) ranging from 1KW to 3KW, it supports loads up to 450kg with exceptional stability.

Key Features & Advantages
Large Hollow Structure
The through-hole design simplifies wiring and piping for robotic arms and turntables, avoiding cable entanglement during 360-degree rotation.
High Rigidity Cross Roller Bearing
Built with a high-precision Cross Roller Bearing, the table can withstand high axial loads, radial loads, and tilting moments simultaneously. This ensures superior stability even under heavy payloads (up to 450kg).
Zero Backlash Performance
Pre-loaded gears eliminate backlash, achieving a repetitive positioning accuracy of ≤15 arcsec (configurable) and lost motion of ≤2 arcmin.
Direct Drive Replacement
Offers comparable precision to DD motors but at a significantly lower cost and with higher torque output.
Flexible Installation
Can be mounted horizontally, vertically, or upside down to fit any machine layout.
Applications
Industrial Automation: Sorting turntables for production lines, rotary tables for assembly lines (e.g., 3C product housing assembly, enabling multi-station continuous operation).
Robotics: Collaborative robot base rotation, palletizing robot steering mechanisms (high rigidity enables rapid robot start and stop).
CNC Machining: Workpiece rotary tables for CNC lathes (high precision ensures dimensional consistency).
Inspection Equipment: Rotary stages for optical inspection and image measurement (repeatable positioning accuracy ensures reliable inspection data).
Heavy Machinery: Rotary mechanisms for heavy parts handling equipment (450kg load capacity suitable for large workpieces).
Motor Compatibility & Installation
The HRT350 series is designed with a flexible input flange. We provide custom input shaft couplers and flanges to match any brand of servo or stepper motor.
Supported Brands: Yaskawa, Mitsubishi, Panasonic, Fuji, Delta, Omron, Siemens, Schneider, etc.
FAQ
Q: What is the difference between the HRT350JS-L2 and ordinary rotary tables?
A: A: Its core advantages lie in "high precision + high load-bearing capacity + hollow design." Ordinary rotary tables are mostly belt-driven (with high backlash), while this model utilizes gears and cross-roller bearings, eliminating backlash and capable of supporting up to 450kg. Its hollow structure is also well-suited for automated equipment.
Q: How do I choose the appropriate reduction ratio?
A: A: It depends on the load and speed requirements: for low speeds and heavy loads, choose a large reduction ratio (e.g., 1000); for high speeds and light loads, choose a small reduction ratio (e.g., 200). We can provide a selection formula and provide recommendations based on customer operating conditions.
Q: Does the equipment require regular maintenance?
A: A: It uses long-lasting grease, requiring no oil changes for 30,000 hours under normal use. We recommend checking the tightness of the fixing screws every 1,000 hours to prevent loosening due to vibration.
Q: Are custom sizes or parameters available?
A: A: Yes! Customizable reduction ratios, hollow bore diameters, and mounting interfaces are available (for example, stainless steel materials can be customized for medical equipment, or heat dissipation structures can be added for high-temperature environments).
Q: What should I pay attention to when adapting to servo motors?
A: A: We are compatible with servo motors from brands such as Panasonic, Delta, and Siemens, and provide motor flange adapters. We need to match the drive to the motor power, and we can provide a complete adaptation solution.
Q: How does a hollow rotary table differ from a planetary gearbox?
A: Unlike a standard planetary gearbox, a hollow rotary table features a cross-roller bearing that supports high axial/radial loads directly on the output flange, eliminating the need for additional external bearings. It also has a large through-hole for wiring.
Q: Can this table replace a Cam Indexer?
A: Yes. Unlike cam indexers which have fixed angles (e.g., 4 stops, 6 stops), the servo hollow rotary table can stop at any angle with high precision, controlled easily by the servo drive.
