Hollow Rotary Actuator Platforms Will Be Delivered to India

Hollow Rotary Actuator Platforms, which have been finished for an Indian customer, will be Delivered to India.

A Hollow Rotary Actuator Platform is a precision mechatronic device that combines a rotary actuator with a large, through-hole in its center. This hollow design allows for the seamless passage of cables, tubing, or laser beams, eliminating the need for complex cable management systems. It integrates a high-torque motor, a high-precision angular contact bearing, and an optional encoder into a single, compact unit.

These platforms are engineered to provide exceptional rotational accuracy, high rigidity, and a low profile, making them ideal for automation tasks requiring both rotary motion and the ability to route utilities through the axis of rotation.

Rigidity of Hollow Rotary Actuator Platforms

The turntable of the Hollow Rotary Actuator Platforms is supported by a set of precision cross roller bearings. The rollers in the bearings are arranged in a 90 degree staggered manner, and the roller diameter is slightly larger than the raceway size between the inner and outer rings of the bearing. This creates a preload force between the inner and outer rings of the cross roller bearings and the rollers. As a result, the servo rotating platform turntable supported by the bearings can withstand various moments such as radial, axial, and overturning, and its rigidity is more than 10 times that of traditional bearings.

Motor can be configured arbitrarily

Hollow Rotary Actuator Platforms can flexibly change the interface size through customized flanges and input shaft holes, suitable for connecting any brand of servo motors and stepper motors, showcasing the versatility of these platforms.

High rotational accuracy

After the assembly of Hollow Rotary Actuator Platforms is completed, the outer diameter and end face of the turntable are ground again with the cross roller bearings of the platform as the rotation center (standard grade is precision turning), ensuring the coaxiality, parallelism and other positional tolerances of the turntable.

It has the characteristics of overload, high rotation accuracy, and low backlash, and is mainly suitable for machine tool CNC rotary tables, mechanical arm joints, fourth axis, indexing heads, military radar, automation, and measurement and testing fields that require high accuracy utilizing hollow rotary platforms.
