Also, customized service and OEM&ODM service are available.
Product Overview
The 115YH is a heavy-duty hollow rotary table for automated machinery that combines a roller cam transmission mechanism with a planetary gearbox and servo motor. Its specified ratings include an allowable thrust load of 550 kgf, allowable inertia torque of 310 N·m, and indexing accuracy of ±15 arcsec. The unit is also rated for an allowable radial load of 9,050 N and an allowable axial load of 11,760 N. These figures provide the starting point for evaluating fixtures and workpieces that place significant loads on the rotary assembly. The hollow center supports machine layouts that require a rotary axis with a central opening.
Performance Specifications
The following specifications can be used as a reference when evaluating the 115YH for a particular machine. Load ratings, positioning requirements, and installation dimensions should be checked against the actual operating conditions.

Installation and Load Assessment
The 115YH dimensional drawing is the reference for the overall envelope, mounting holes, and drive interface. Check the drawing against the machine layout before preparing the mounting structure. Allow for the required installation space and verify that the mounting and connection points match the adjoining components.
For a loaded rotary assembly, the force values alone do not describe the complete operating condition. Record the direction in which each load acts and the point at which it is transferred to the table. The workpiece and fixture center of gravity should also be identified. These details, together with rotational inertia and operating speed, are needed to judge whether the 115YH is suitable for the intended duty.
Where the 115YH May Be Applied
The model can be considered for machine functions that combine rotary indexing with relatively high fixture or workpiece loads, including:
- Assembly positioning: holding and indexing loaded workpieces or fixtures during automated assembly operations.
- Workpiece orientation: turning a loaded component to a defined angle or position within an automated process.
- Inspection positioning: presenting different sides or features of a component at specified inspection positions.
- Special-purpose automation: providing a hollow rotary axis where the machine design also requires defined load ratings and indexing accuracy.
These are potential application areas rather than a blanket suitability statement. The final decision depends on the workpiece and fixture arrangement, load distribution, required motion, and machine installation.
Drive Configuration and Application Data
The standard drive arrangement uses a planetary gearbox with a 20:1 reduction ratio and a servo motor. The maximum input speed is specified as less than 1,000 r/min. The servo motor and operating settings should be checked against the required indexing movement and the load imposed by the workpiece and fixture.
For a configuration review, prepare the following application information:
- Load profile: workpiece and fixture weight, center of gravity, rotational inertia, and the radial and axial loads acting on the table.
- Indexing cycle: required indexing angle, cycle time, operating speed, and positioning accuracy.
- Mechanical interface: machine layout, mounting dimensions, connection points, available installation space, and motor arrangement.
- Control system: servo motor specifications and the motion-control requirements of the machine.
Relevant machine drawings and operating parameters help determine whether the proposed arrangement is technically suitable. Any non-standard dimensions or drive arrangements should be reviewed and confirmed before an order is placed.
FAQ
Q: Does the 550 kgf allowable thrust load indicate the maximum workpiece weight?
A: No. The 550 kgf figure is an allowable thrust-load rating, not a universal workpiece-mass limit. The load direction, point of application, center of gravity, rotational inertia, and operating speed all affect the assessment.
Q: Which positioning figures should be considered when selecting the 115YH?
A: The specified repeat positioning accuracy is ±5 arcsec, the indexing accuracy is ±15 arcsec, and the minimum setting unit is 0.001°. These are separate specification items. Check the requirement of the machine against the relevant figure rather than treating them as interchangeable.
Q: What are the allowable radial and axial loads?
A: The specified allowable radial load is 9,050 N, while the allowable axial load is 11,760 N. During selection, identify the direction and application point of each force and review these loads together with the fixture layout and operating conditions.
Q: What information is needed before the 115YH can be configured for a machine?
A: Provide the workpiece and fixture weight, center of gravity, rotational inertia where available, indexing angle, cycle time, operating speed, positioning requirement, installation dimensions, and relevant machine drawings. Servo motor and motion-control details are also useful for reviewing the drive arrangement.
