IKO Rotary Stroke Bushing

The inner surface of the outer cylinder is finished by precision grinding, resulting in smooth motion of the ball elements. Each of the ball elements is held in a separate hole and smooth motion is achieved for both rotational motion and linear motion. The retainer moves half the length of the linear motion, therefore, the stroke length is limited to approximately twice the length the retainer can travel within the outer cylinder. The actual stroke should be limited to 80% of the maximum stroke as listed in the dimension tables.High PrecisionHigh-carbon chromium bearing steel is used for the outer cylinder. It is heat treated and ground to achieve high rigidity and accuracy.Light Weight and Space SavingThe use of an aluminum alloy for the retainer and the thin-wall outer cylinder makes the STROKE BUSH light weight and compact.
