The MGPM-H/R is a compact body, end lock actuator integrated with internal guide shafts to isolate the load bearing from the movement of the actuator’s rod and seals. The end lock can be specified for either the head end (H) or rod end (R) of the stroke. The brake spring, end lock mechanism will engage when air pressure is lost for drop prevention applications and can be released by reintroducing air pressure or via a manual release bolt. The (M) carbon steel alloy slide bearing provides lateral stability protecting it from side load impacts, suitable for stopping applications.
