Drop Prevention
SMC has numerous solutions for load drop prevention. End lock cylinders lock and hold the load at the end of stroke. Locking cylinders have the ability to lock a load anywhere within the stroke. Series ASP is a speed controller with an integrated pilot check valve. This combination makes it possible to control cylinder speeds and permits temporary intermediate stops. 5-port solenoid valve combines the double check block with a 3-position exhaust center solenoid valve will enable the cylinder to stop in the middle of maintain its position for long periods of time.

The CXSM-R slide bearing type provides lateral stability protecting it from side load impacts.
MB End Lock
The MB series medium duty tie rod cylinder offers an improved design that enhances cylinder operation and ease of use. The standard air cushion utilizes a floating cushion seal to eliminate piston rod bouncing. The cushion volume has been elevated permitting about 30% more allowable kinetic energy absorption. The port and captive cushion adjustment valve are located on the same side of cap for heightened access. The MB series is available with many standard options, which include stroke adjustment, tandem, high/low temperature seals, heavy rod scraper, non-rotating rod, double rod and many more.
MGG End Lock
The MGG integrates a round body, end lock cylinder for its power source with external guide rods to isolate the load bearing from the movement of the actuator's rod and seals for a one piece unit. 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. It is enhanced with shock absorbers at the end of stroke for maximum kinetic energy absorption. Non-rotating accuracy ranging from +/-0.02° for 100 mm bore to +/-0.07° for 20 mm bore. 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.
MGP End Lock
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.
MGZ End Lock
The MGZ series is a non-lube double power air cylinder available in both rotating and non-rotating styles. The MGZ's unique design doubles the pressurized area for extension making the MGZ an ideal cylinder for lifting and pressing operations. The front end lock style MGZ holds the rod when extended.
MTS End Lock
The MTS cylinder provides superior non-rotating accuracy and linear stability in a compact package. Traditional non-rotating cylinders typically can only hold position to within 0.5° and have inherent sealing problems. Integrating a ball spline as the rod bearing, this cylinder approximates the non-rotational accuracy of a guided cylinder without the added space requirements of external guide rods. In addition, a special rod seal design limits leakage to the equivalent of a round piston rod seal. An optional end lock retains the rod in the retracted position even in the event of loss of air pressure for added safety. Mounting can be done from four precisely machined faces with parallelism of less than 0.1mm.
MXQ End Lock
The MXQ precision slide is ideal for applications requiring closely held parallelism and perpendicular specifications.
