HRG 280 Series Hollow Rotary Table
A hollow rotary platform is a mechanical device designed to
facilitate precise rotational motion while featuring a central
opening that allows for the passage of cables, pipes, or other
components. This innovative design enables efficient integration
into various systems, reducing clutter and improving functionality
in applications such as robotics, automation, and CNC machining.
The platform is typically supported by high-quality bearings,
allowing for high load capacity, minimal backlash, and exceptional
accuracy in positioning. Its versatility makes it suitable for a
wide range of industries requiring reliable and controlled
rotational movement.
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.
Efficient Torque Output:
Utilizes a single-stage helical gear reduction mechanism to
increase output torque, with gears rated below level 5 for
precision.
Robust Construction:
Built to endure a variety of operational stresses while maintaining
high performance, making it suitable for industrial and automation
applications.
