DN85 Hollow Rotary Actuator Rotating Platform High Accuracy Turntable, Fits Nema 17 Stepper Motor

More Features:

High Accuracy Rotating Platform: 1 arcmin positioning accuracy and 15 arcmin repeated positioning accuracy, which is dramatically growing in high-precision industrial automation equipment, glue dispensing machines, the 4th or 5th axis of machine tools, packing machines, photoelectric and visual inspection equipment, indexing plate, laser printer, sorting machine, robot joint, etc.
Equipped with Crossed Roller Bearing: considering the accuracy and stability that may be affected by the lateral force from different directions, the high rigidity crossed roller bearing was adopted, which features high rotational accuracy, stable rotational torque, and high loading capacity, which can ensure the stability and high precision of the rotating platform.
The rotary actuator comes with a hollow design, while the stepper and servo motor could connect the actuator at the side, which is convenient to wire and add the air pipe, and non-considering twining problems.
Directly connected with a stepper/ servo motor, compared with traditional rotary tables, it is available to support more stable rotating, and high-accuracy controlling and positioning, furthermore, it can save time and costs of mechanism design, complex table installation, belt adjustment and calibration, etc.
High-quality Material: the actuator is made of 6061 aluminum alloy (with the blackening process), high-accuracy gears, high rigidity crossed roller bearings and shafts, which support longer service life.
