Re: Is it possible to change the BP motor to eliminate shifting?

Gary, I Googled and found below info at http://www.agi-
automation.com/Rotary-Actuator-agr1.htm This has great
possibilities with computer control of airflow. Any idea how that
might be done? Thanks Keith

Built-in adjustable hardstops on output flange stop against a dowel
pin embedded in the body to prevent pinion breakage and give
accurate specific rotation requirements.

Two large bearings, one on either side of the pinion, provide for
steady output flange with high loading capacity.

Ultra high torque-to-weight ratio for faster cycle times.

Compact body design to fit in tight space applications.

Units are permanently lubricated for non-lube air operation,
allowing for compliance with OSHA regulations.

All rotary units have zero backlash at either end of rotation,
keeping the output flange against the hardstop.

Built-in adjustable flow controls allow for maximum cycle times and
smooth deceleration.

Proximity switches are available to monitor end of rotation.
