The Dolphin™ Actuator is a basic model in a series of highly specialized shower actuators optimized for their respective range of applications. The oil lubricated "Ball-Reverser" design has three balls in tracks in a ball reverser screw. The actuator can develop 1000 lbs of thrust. Length of stroke is fixed as determined by the length of screw flights installed in the unit. Dimensions are identical to the ROLLTECH® Actuator.

Additional Information

Additional Information

 N/A Lightweight and economical - ideal where fixed stroke length and stroke rate is acceptable - no control panel required
  • Compact design - for easy installation and maintenance.
  • Four (4) fixed speeds or adjustable stroke rate available.
  • Variable speed requires control panel, fixed speed does not require control panel.
  • "Ball Reverser" design is simple, no reversing switches, no need to reverse motor, instant turn around at end of stroke.
  • "Gimbal Mounting" for reduced load during oscillation.
  • Integral felt protection proximity switch recommended.
The Dolphin™ Actuator is mounted in a gimbal mounting near the balance point of the actuator allowing some multi-directional movement which provides a non-binding movement of the actuator. This arrangement is very forgiving of slight misalignment of the actuator and shower and prevents premature failure due to excessive binding loads. Split bearings with UHMW Polyethylene liners and anti-rotation bars keep the shower in correct position and allow removing the shower from the paper machine and replacing it again without realigning the bearings.
