Hollow Bore Rotary Table Ready for Korean Client

Hollow Bore Rotary Table is a high-precision electromechanical integrated rotary motion actuator, also known as servo rotary platform or hollow shaft rotary platform. Its core design feature is a huge hollow shaft that runs through the body, which brings multiple advantages.

Hollow rotary platform is a widely used rotating component in the field of automation, also known as hollow rotary actuator, programmable servo rotary table, and hollow shaft rotary caliper.

Its biggest structural feature is the hollow aperture in the center, which allows cables, water pipes, gas pipes, etc. to pass through it. During the rotation process, wiring and pipeline installation can be easily achieved, greatly facilitating axial transmission of optical fibers, liquids, gases, cables, etc. without the need to reserve special pipelines, providing great flexibility for industrial automation and robot applications.

The turntable of a Hollow Bore Rotary Table is usually supported by precision crossed roller bearings

with rollers arranged in a 90 degree staggered pattern and a diameter slightly larger than the size of the inner and outer raceway of the bearing, creating a pre tension force between the various components of the bearing. This endows the turntable with strong load-bearing capacity, capable of withstanding various moments such as radial, axial, and overturning, and its rigidity is several times higher than traditional bearings. At the same time, it adopts a single-stage spiral gear reduction method to increase the output torque, with high gear accuracy level and flexible clearance adjustment mechanism. The backlash is extremely small, and the repeated positioning accuracy can reach less than 5 arc seconds. The positioning accuracy is ≤ 1 arc minute, which can achieve high-precision angle positioning and arbitrary angle cutting.

In terms of motor configuration,

the hollow rotating platform is extremely flexible and can be adapted to any brand of stepper motor or servo motor on the market. By customizing the flange and input shaft hole, the interface size can be easily changed to meet different driving needs. Its output table sizes are diverse, with common specifications including 62, 85, 130, 200, 280, etc. It also has reinforced and heavy-duty versions to meet the diverse needs of different industrial scenarios such as chemical, power, petroleum, steel, etc. In addition, the motor connection direction also provides two methods: side connection and right angle connection, providing more design space and flexibility for automation engineers and designers.

It integrates high-precision turntable bearings and servo drive systems

(usually directly connected to servo motors through high-precision reducers such as planetary or harmonic reducers), achieving extremely high repeatability positioning accuracy, high rigidity, high torque, and excellent motion stability. Its motion control method is no different from ordinary servo motors, and it can easily achieve seamless integration and complex trajectory control with multi axis motion control systems.

Hollow Bore Rotary Tables are widely used

in fields that require strict precision and wiring, such as industrial robots (joint drive), precision alignment platforms (LCD, semiconductor detection), automation equipment (laser processing, sorting, handling), as well as high-precision industries such as medical and aerospace. They are one of the core basic components in the field of modern precision automation.
