  • Low torque required to drive the load due to high efficiency ball screw.
  • Linear bearings provide low stick slip for precise positioning and ease of moving the load.
  • Precision linear rail system supports the load through the entire stroke length.
  • Rugged aluminum extrusion supports the linear rail system through the entire stroke length.
  • Motor mounting for all NEMA 34 and 42 frame motors.
  • NEMA standard gearheads mount directly to the unit.
  • Stroke lengths to 11 feet.
  • NU-MATE mounting pattern is standard.
  • Minimal deflection due to the square rail support system.
  • Bellows available for severe duty applications.
  • Recirculating twin ball tracks in the screw and on the rails provide greater accuracy.
  • Load locking spring prevents load from free falling in the event the ball bearings are lost from the nut.
