Long Stroke, High Speed, High Force
The Tac LS ball screw linear actuator series was developed for long stroke applications. This high quality, durable linear actuator, is constructed using rugged aluminum alloy cylinders and chrome plated heavy wall steel pistons. Its small size, as well as the ease of adapting it to any standard unit mounting style, makes the series of LS electric linear actuators a good fit in most linear motion industrial applications.

1. Maximum velocity and maximum screw speed may not be achievable at maximum stroke.
2. Larger Motor or Gearhead Frames and longer stroke lengths are available upon request.
3. All inertia values are at the input shaft and are representative of typical pulleys, bushings, couplers, etc. Actual values may vary due to motor selection.
4. Weight values are for reference only and vary depending on configuration.
"U" Parallel offset configuration
"L" Inline configuration
