SMC Specialty & Engineered Cylinder Designs
When your application requires that a task be performed that can not be completed with standard air cylinders, SMC can help you find the solution. SMC offers a variety of specialty air cylinders including Sine (smooth acceleration), Load Stopping, and Clamp to name a few. For example, the transportation of delicate items often requires greater control of cylinder speed, acceleration and deceleration than is afforded by traditional pneumatic cylinders. For this reason, SMC has developed a RE series of sine cylinders. These cylinders facilitate high-speed transportation of work but have very smooth actuation (similar to sine wave).
For your demanding applications our large engineering department can customize a product solution for you. Need a special variation on our standard pneumatic rotary actuator? No problem. We can create a three-stop rotary unit to meet your custom needs.
The CLA2 cylinder acts as an air-operated brake with spring-backup. When external position feedback sends a signal to an air valve, the brake is actuated and fast-acting shoes grab the actuator shaft. When pressure is removed, the spring automatically locks the brake onto the shaft. Three locking mechanisms are available: spring lock, air pressure lock and air/spring pressure lock. The CLA2 locks in either direction, comes in five bore sizes, and is available with PT or NPT ports. Other features include non-lube operation, air cushions, and seven mounting styles.
Double acting, single rod cylinder w/lock
Mounting: basic, axial foot, rod flange, head flange, single clevis, double clevis, center trunnion
Bore sizes (mm): 40, 50, 63, 80, 100
Strokes up to 1500mm (depending on bore size & mounting)
Auto switch capable

The series CLM2 offers a brake mechanism to stop the piston rod at any position while retracting or extending. With three different brake mechanisms and four bore sizes available, SMC gives you the choice of the best unit for your application. The compact and lightweight CLM2 is a part of the CM2 product line.
Fine lock cylinder, CLM2
Double acting, single rod
10 mounting options available
Air hydro option available
Auto switch capable
Compact cylinder series CLQ offers drop prevention when the pressure of air source is decreased or the residual pressure is released. The CLQ has a low profile design, with a compact lock unit. Available in 8 bore sizes ranging from 20 to 100mm, and is auto switch capable.
Low profile with compact lock unit
Two types of mounting
Locking is possible at any position within the entire stroke
Locking direction is selectable
Easy manual unlocking
The CLS series cylinder with lock is ideal for applications requiring intermediate and emergency stop and drop prevention. The compact lock unit is lightweight and saves space. A switch is optional on the brake cylinder so the operating state of the lock unit (brake piston) can be detected using the switch signal. By separating the lock mechanism and the brake cylinder, SMC has minimized the influences of unlocking air quality such as moisture and condensation.
Fail safe construction
Equal holding force in both directions
Lock unit switch
Improved maintainability
Strokes to 1600 depending upon mounting brackets
Auto switch capable cylinder

The CNA2 series cylinder with lock is suitable for mid-stroke stops, emergency stops, and drop prevention. An equal holding force in extending and retracting directions make it possible to lock at either end of the stroke. High reliability and stable holding force are maintained by using a substantially lengthened brake shoe with superior wear resistance. The locking mechanism is isolated from lock release air, so lock function is not diminished by excessive dirt or drain in compressed air.
