The MGPs is a compact body actuator integrated with internal oversized guide shafts to isolate the load bearing from the movement of the actuator's rod and seals. The carbon steel alloy slide bearing provides lateral stability protecting it from side load impacts resulting in a non-rotating accuracy of +/-0.05° for 50 mm bore and a non-rotating accuracy of +/-0.04° for 80 mm bore. Compared to the standard MGP, the MGPS increases anti-lateral load by 10%, increases eccentric load resistance by 25% and increases impact load resistance by 140%.
