THK KRF Compact Electric Linear Actuator

The THK KRF Compact Electric Linear Actuator is a fully enclosed actuator designed for compact machine layouts. It uses magnetic strip seals to help prevent foreign materials from entering the actuator. The seals also reduce dust generation by avoiding contact with the seal surface.

The KRF uses a U-shaped steel outer rail for high rigidity and strong resistance to moment loads. This allows the actuator to remain compact while handling larger loads. It is also available with dedicated TSC, TLC or THC controllers for easier setup.

The KRF series is available in KRF4, KRF5 and KRF6 models. Maximum strokes range from 300 to 800mm, depending on the model.
