The MGPW is a compact body actuator integrated with internal guide shafts to isolate the load bearing from the movement of the rod and piston seals. The (A) press fitted high precision ball bushing is suitable for minimizing the actuator's plate displacement. Non-rotating accuracy +/-0.01°. The (L) high precision ball bushing allows for smooth operation that ensures stable travel resistance. Non-rotating accuracy +/-0.03°. The (M) carbon steel alloy slide bearing provides lateral stability protecting it from side load impacts. Non-rotating accuracy ranges from +/-0.03° for 63 mm bore to +/-0.05° for 20 mm bore
