Cost Effective, High Quality, High Speed, High Force
The Tac VT ball screw linear actuator series was developed to meet higher thrust load requirements at somewhat faster velocities than the ET series actuators, with the same high quality, rugged durability. Using an aluminum body with steel components, chrome plated heavy wall steel piston, and steel/bronze anti-rotation, this linear actuator ensures rigid alignment.

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
