82YH heavy-duty roller cam hollow rotary table overview
The 82YH heavy-duty roller cam hollow rotary table is designed for automated equipment that requires rotary indexing and precise positioning under load. It uses a roller cam drive mechanism, a crossed roller bearing, and a planetary gearbox with servo motor drive. The reduction ratio is 20:1. The specified allowable thrust load is 300 kgf, and repeatability is ±5 arcsec.
Servo motor selection depends on the operating requirements of the equipment. Hansheng Automation can recommend a suitable configuration after reviewing the application.
Key features
Roller cam drive mechanism
The roller cam mechanism converts input rotation into controlled rotary movement for indexing applications. Its suitability depends on the required motion profile, load conditions, and operating cycle.
01
Hollow center design
The hollow center provides space for cables, pneumatic lines, shafts, and other components that need to pass through the rotary axis. The available opening and installation arrangement should be checked against the equipment layout.
02
Crossed roller bearing
The 82YH uses a crossed roller bearing to support the rotary assembly. This bearing arrangement accommodates combined axial and radial loads. Load conditions and mounting accuracy should be checked when selecting the unit.
03
Planetary gearbox and servo drive
The drive system consists of a planetary gearbox and a servo motor. Motor selection depends on the workpiece load, rotational inertia, operating speed, acceleration, duty cycle, and control system.
Hansheng Automation can recommend a motor configuration based on these requirements.
04
Positioning accuracy
The specified repeatability is ±5 arcsec, while the indexing accuracy is ±20 arcsec. These values describe different aspects of positioning performance and should be evaluated separately. The minimum setting increment is 0.001°.

- The servo motor configuration should also be confirmed for each application. Customers can provide their operating requirements for technical review and configuration recommendations.
Precision machining of the 82YH output flange
The output flange connects the rotary table to the customer's fixture or equipment. Its mounting face, center bore, and hole pattern must meet the drawing requirements for proper assembly.
The machining process focuses on dimensional relationships between these features and the tolerances specified on the component drawing.
Step 1: Drawing review and datum planning
The component drawing is reviewed to identify critical dimensions, reference faces, the center bore, and mounting-hole positions. Machining datums are established to control the relationship between these features.
Step 2: Blank preparation and inspection
The component blank is checked against the drawing and production requirements. The material condition, machining allowance, and reference surfaces are reviewed before machining.
Step 3: CNC turning
The specified cylindrical surfaces, locating diameters, center bore, and mounting face are machined according to the drawing. Related features should be referenced consistently to control concentricity and face alignment.
Step 4: Drilling and tapping
The mounting-hole pattern is machined to the specified dimensions and positions. This includes the Ø11 mounting holes and M6 threaded holes shown on the drawing. Hole positions and thread depths must meet the requirements of the mating components.
Step 5: Surface finishing and deburring
Machined surfaces and mounting interfaces are finished according to the drawing. Burrs and machining residues are removed to prevent interference during assembly.
Step 6: Dimensional inspection
The finished component is checked against the drawing. Inspection covers the center bore, locating diameters, mounting-hole positions, face runout, concentricity, and other specified tolerances.
Controlling the relationship between the mounting face, center bore, and bolt pattern helps ensure that the output flange fits the rotary table and its mating fixture.
The actual machining sequence and inspection criteria depend on the approved production drawing and manufacturing route.
Typical applications
The 82YH can be evaluated for automated equipment that requires rotary indexing and support for relatively heavy fixtures or workpieces.
Potential applications include:
- Automated assembly equipment: Rotary stations for positioning workpieces during assembly.
- Inspection and testing equipment: Indexing fixtures that move workpieces into defined inspection positions.
- Heavy-duty rotary fixtures: Applications requiring a hollow center and a rotary drive arrangement.
- Automated production lines: Rotary stations for transferring or positioning components between workstations.
Suitability should be assessed against the workpiece mass, center of gravity, required cycle time, positioning accuracy, mounting orientation, and operating conditions.
Configuration and customization support
Selecting a rotary table requires an assessment of the actual load and motion requirements. Workpiece mass, center of gravity, overhang, rotational inertia, acceleration, and operating cycle all affect the drive configuration.
For the 82YH, Hansheng Automation can provide recommendations for servo motor and drive configuration.
To support the selection process, customers should provide:
- Workpiece and fixture details: Total mass, dimensions, center of gravity, and mounting arrangement.
- Motion requirements: Indexing angle, cycle time, operating speed, and positioning accuracy.
- Installation details: Mounting orientation, available space, center-hole requirements, and cable or pneumatic routing.
- Control requirements: Servo system preferences, controller interface, and available power supply.
A component drawing, equipment layout, or description of the operating conditions can help the engineering team evaluate the application and recommend a suitable configuration.
