© BCS Motion 2011 KS Type Linear Actuators / SAR are equipped with a dust- proof strip to prevent wear particles from flying out. Because of the dust-proof design, this type of Linear Actuators / SAR is ideal for the manufacturing of semiconductor equipment, LED examination equipment, medical equipment, etc. The Linear Actuators / SAR KA is actuated by a motor-driven ballscrew and is guided by a linear guideway. The stage base is a lightweight design made of aluminium. It is suitable for semiconductor and industrial automation applications. The Linear Actuators / SAR KK is a slider actuated by a motor-driven ballscrew and guided by a linear guideway with a U-shaped rail. The slider acts as the ballscrew's nut and the guideway's block.
