Heavy Load Linear Stroke Rotary Bushings ST8 10 12 16 20 Linear Bearings

The stroke rotary bushing is a linear and rotary motion mechanism that utilizes ball elements for rotary motion between the outer cylinder and the shaft. It is compact and can withstand high loads. The retainer is made of a light metal alloy with high wear resistance. Smooth motion is achieved under high speed and high acceleration conditions. While linear motion is limited to a specific stroke length, the combination of rotary and stroke motion is achieved with little frictional resistance. The stroke rotary bushings can be easily used in a variety of applications.
