Rod Lock – Locking
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.
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.
The series CLG1 is provided with a compact locking mechanism that locks in both directions. The piston rod can be locked in either direction of its cylinder stroke. It is suitable for intermediate stops, for emergency stops, and for drop prevention. The CLG1 fine lock cylinder is part of SMC's CG1 cylinder series.
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.
The CLJ2 offers a brake mechanism to stop the position rod at any position while retracting or extending. Choose from three different brake mechanisms to select the unit best suited for your application. Compact and lightweight, the CLJ2 is part of SMC's CJ2 product line.
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.
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.
SMC'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.
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 SMC product).
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.
SMC'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.
The CL1 series lock-up cylinder is a self-locking style that contains a ring that is tilted by a spring force, which is further tilted by the load that is applied to the cylinder, thus locking the piston rod. This cylinder is suitable for intermediate stops, emergency stops, or for drop prevention.
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.
Series RLQ was developed to provide the safety of drop prevention, at any point of the stroke, should the air supply be cut off. The RLQ benefits from additional features such as its own built in air cushion and lock unit, standardized bypass piping and home position holding function. The new series RLQ is the perfect solution for applications which require larger kinetic energy, high stroke repeatability and decreased sound levels. Series RLQ, is currently available in bore sizes of 32, 40, 50 and 63mm, with standard stroke options of between 20 – 100mm, series
The MGP is designed for high side load applications found in material handling, lifting and stopping. The cylinder utilizes an ultra-compact design by incorporating the cylinder body as part of the guide body. As the stroke length increases, so does the bearing length, thus enhancing the cylinder's load bearing capacity. Conventional designed guided cylinders have a set bearing length resulting in dramatic decreases in side load capacity as stroke lengths increase. The MGP is the latest generation of guided cylinders and offers higher load capability, longer strokes, 2 port locations, switch mounting grooves on two sides, and a more versatile T-slot mounting than the MGQ series. Order made options for this series include adjustable air cushions, heavy duty guide rods, copper free, high temperature, and low speed.
