Mounting to Rotary Actuators
• Do not tighten grub screw
4
against the thread of spindle
9
• When in use, the flat side of the spindle 9 must move 0
↔
100% in front of the arrow
26
• When the product temperature rises, the drive shaft
1
increases in length Therefore, the rotary adapter
3
must be
mounted so there is approximately 1 mm (0 04 in ) of clearance between the drive shaft
1
and the rotary adapter
3
The
clearance is achieved by placing an appropriate number of washers
5
on the feedback spindle
9
before attaching the
rotary adapter Two washers should result in a clearance of 1 mm
