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 REB series is a sine rodless cylinder, with a maximum speed of 600mm/s, available in 3 bore sizes. Model REBR, a non-integrated guide, direct mount type is capable of mounting from the top or one side. Compact, external dimensions allow the REBR to be used when space is very limited. Model REBH is an integrated guide type cylinder. The use of a linear guide facilitates a large load, large moment and high precision. The REBH is available in a one or two axis style.

The transportation of delicate items often requires greater control of cylinder acceleration and deceleration than is afforded by traditional air cushions. For this reason, SMC has developed the REC sine cylinder. The term "sine cylinder" is derived from the shape of the velocity curve at both ends of stroke. This control is achieved with the addition of two grooves on each cushion spear which results in a more gradual initial acceleration or deceleration and smooth transition to or from full speed operation. To accomplish this type of motion with a traditional cylinder typically requires extensive external flow control. REC is a repairable basic cylinder.
Accessory: mounting brackets
Types: C (single clevis), D (double clevis), F (flange/foot), L (axial foot), T (trunnion)
Applicable Bore Sizes: 20mm, 25mm, 32mm, 40mm

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).

3 position cylinder series RZQ provides intermediate stop mechanism. 2 intermediate strokes are possible with only a small extension in total length. First stage stroke can be specified without changing the overall length. High accuracy is achieved by an intermediate stop method of pressing metallic components against each other. A tube rod with a large bore which is 70% the piston diameter is used to withstand lateral load. Wide variations of mountings are available.
