THK KRF Series Electric Actuators

The THK KRF Series Electric Actuator is a compact, fully enclosed actuator designed for smooth and precise linear motion. It uses a ball screw and a steel U-shaped outer rail to provide high rigidity while keeping the actuator compact. The fully enclosed design uses magnetically held strip seals to help prevent foreign materials from entering the actuator. The non-contact seal design also helps reduce dust generation.

The KRF Series is available with 6 mm or 10 mm ball screw leads, depending on the model. KRF5 supports strokes up to 550 mm, while KRF6 supports strokes up to 800 mm.

Available models include KRF5-06-0050A-0-X-GR, KRF5-06-0100A-0-X-GR, KRF6-06-0100A-0-A0-GR, KRF6-06-0450A-0-A0-GR and KRF6-10-0300A-0-A0-GR. These configurations cover 50 mm to 450 mm stroke options with 6 mm and 10 mm ball screw leads.
