Technical information for ball screw linear actuators Efficiency and self-locking: The low rolling friction of ball screw linear actuators give them a mechanical efficiency of up to 95%. Operating duration can be 100%. Due to low rolling friction ball screw linear actuators are not self-locking. A brake mechanism must be installed where selflocking is required (reduction gear or motor brake). This is a must by vertical installations. Operating temperature: Ball screw linear actuators can be used with normal loads within a temperature range of -20 to +80 °C. Temporarily up to +110 °C. A prerequisite...
