GS40 linear actuators combine a brushless servomotor, an inverted roller screw, and an encoder/resolver feedback source into a single compact assembly. The 99-mm frame size unit offers a range of strokes from 152 to 457 mm, continuous force ratings up to 5,337N, and linear velocities to 635 mm/sec. According to the company, the brushless servo design allows them to be used in state-of-the-art, closed-loop servo systems where electronic control of positioning and velocity is required.

One piece Reli-a-Flex couplings are designed to provide accurate transfer of motion between two rotating shafts, while at the same time adjusting for parallel and angular misalignment. According to the company, this line differentiates itself with its patented slot design, which maintains a constant pivot length to minimize stress variations. Also, the pivot points travel backward and forward without changing the center piece angle uniform stress levels and accurate angular rotation. Reliance Gear Co.

These analog encoders have a 4- to 20-mA interface. A current signal between 4 and 20 mA, proportional to the angular position of 0 to 360º, is reportedly given by the encoder with the unit size of 58 mm and a 10- or 12-mm shaft. The sensor part and interface are constructed to be galvanically isolated.
