The MLGP-B/F is a compact body, locking actuator integrated with internal guide shafts to isolate the load bearing from the movement of the actuator's rod and seals. The locking mechanism can be specified for either the extension side (F) or the retraction side (B) of the stroke. The brake spring, locking mechanism will engage when air pressure is lost for drop prevention applications and can be released by reintroducing air pressure or via a manual process. The (L) high precision ball bushing allows for smooth operation that ensures stable travel resistance, suitable for pushing and lifting applications. The (M) carbon steel alloy slide bearing provides lateral stability protecting it from side load impacts, suitable for stopping applications.
