When working with delicate materials such as Silicone wafers, magnetic
disks, or LCD substrates, non-shock actuation must be balanced with
high speed/throughput. The REA provides the features needed to allow
rapid transfer with a speed of up to 300mm/sec but virtually eliminates
shock impact. Integrated cushion spears allow smooth acceleration and
deceleration, while also simplifying construction of the cylinder.
Based on the magnetically coupled cylinder concept, the REA’s resulting
smooth acceleration and deceleration occurs without influence from
load, speed, or even pressure fluctuations. REA is available in 5 bore
sizes from 25mm to 63mm and strokes up to 1000mm

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 similar to the NCG series.
