NOTE:
Quantities shown are as required per end cap option
specified.
Stroke adjusters will reduce the angle of rotation by 10° or
30° in either or both directions. Typical applications are for
initial set up purposes where exact rotation requirements
may change between various operations.
CAUTION: Before making any adjustments, turn off system
pressure and ensure that no residual pressure
exists in the actuator.
Standard cushions operate over the last 30° of rotation.
Stroke adjusters will decrease the cushion length by the
same amount. For example, reducing the rotation by 5°
yields 25° cushion length.
To Adjust:
1. Loosen Jam Nut, #40.
2. Turn Stroke Adjuster, #41 clockwise to reduce stroke,
counterclockwise to increase stroke.
3. Tighten Jam Nut, #40.
4. Resume system pressure.
