HRG 170A Series Hollow Planetary Integrated Rotary Table
A Hollow Rotary Platform with Planetary Gearbox is a mechanical
system that combines a hollow rotating structure with a planetary
gearbox for precise movement. The hollow design allows for easy
routing of cables or fluids, while the planetary gearbox provides
high torque and reduced backlash, enabling smooth and accurate
rotational motion. These platforms are commonly used in robotics,
CNC machines, and automated systems.
Key Features
High Precision:
Achieves repeat positioning accuracy of less than 5 arc seconds,
ensuring reliable performance in demanding applications.
High Rigidity:
Supported by precision crossed roller bearings, the platform can
withstand significant radial, axial, and overturning forces,
providing over ten times the rigidity of traditional bearings.
Flexible Motor Compatibility:
Easily configurable to accommodate various brands and types of
motors, including servo and stepper motors, through customizable
flanges and input shafts.
