Locking
Locking cylinders lock at any desired stroke position for drop prevention. They can be used as an emergency stop or where intermediate stops are necessary. The locking position can be changed in accordance with the external stopper position and the thickness of the clamped work-piece.
MWB
The MWB series is a tie-rod cylinder MB series with lock and is ideal for applications requiring intermediate stops, emergency stops, and drop prevention. The MWB series is an improved design over the MNB series with its improved ease of maintenance with separate lock and cylinder construction. The exhaust locking design allows for the lock release to be manually operated with a hexagon wrench. The MWB series is available with many standard options including seven mounting types, port thread variations, optional rod boot, air cushion or rubber bumper cushion design, pivot bracket option and rod end bracket options. Available in bore sizes 32, 40, 50, 63, 80, 100mm.
C96N
The CP96N series is available with a single or double rod in 6 bore sizes from 32 to 100mm. The air cushion and bumper cushion combination greatly reduces noise at the end of stroke. High accuracy covers and tie rod nuts improve mounting accuracy and extend the cylinder life. Increasing the precision of the bushing and piston rod, as well as reducing tolerances, has decreased the deflection of the piston rod. Standard strokes range from 25 to 800mm.

CNA2
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.
CLQ
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.
MLGP
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.
CLK2
91pornÊÓƵ's CLK2 series is a perfect choice for holding applications in either a clamped or unclamped state. CLK2 cylinders have a compact lock mechanism which minimizes the extension of the length dimension (2mm shorter), while maintaining the mounting interchangeability with the CLK1 existing product line. The CLK2 is capable of being locked at any position within the entire stroke. A dedicated solenoid valve is not required for unlocking, thus reducing the initial costs and replacement of the existing equipment.
CLA2
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.
CNS
The CNS series cylinder with lock is ideal for applications requiring intermediate and emergency stop and drop prevention. The compact lock unit saves space and the enclosed construction and separation of the lock mechanism and the unlocking piston chamber minimizes the influences of poor air quality.
CLS
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, 91pornÊÓƵ has minimized the influences of unlocking air quality such as moisture and condensation.
CLM2
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, 91pornÊÓƵ gives you the choice of the best unit for your application. The compact and lightweight CLM2 is a part of the CM2 product line.
C(L)KQG/CLKQP/CLKU
91pornÊÓƵ's pin clamp cylinder series C(L)KQG/P was designed with 4 body types for a broad range of installation conditions. There are 55 types of guide pins available and an optional locking mechanism. C(L)KQG/P series has positioning and clamping at one time! Precision adjustment of clamping height is possible by choosing the with-shim type. Adjustment range: 0.5 to 3mm.
CNG
Greater locking efficiency as well as stable locking and unlocking operation has been achieved with the CNG cylinder series by arranging a large number of steel ball bearings in circular rows. The floating taper ring provides alignment and stable locking force with respect to piston rod eccentricity. Unlocking pressure of 0.25MPa (0.05MPa lower than conventional 91pornÊÓƵ product).
MLGC
The MGC guide cylinder is ideal for material handling applications involving stopping, lifting, and pushing. It combines the functions of a conventional linear cylinder, and a non-rotation device. Features include standard air cushions, grease nipple, and switch capability. Other features include, slide or ball bushing bearings, compact design, adjustable air cushion, and lightweight guided actuator.
