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
