Rodless Pneumatic Cylinders and Rodless Actuators

At SMC we are rolling out upgraded mechanically jointed rodless cylinders that will give our customers improved performance and functionality. The MY1H-Z linear guide cylinder, ideal for high repeatability applications, has a new magnetic dust seal band minimising the number of external particles entering the system.Following requests for a lighter mechanically jointed rodless cylinder with improved auto switch mounting, we are pleased to unveil our new MY1B-Z Series. Up to 17% lighter than our existing rodless cylinder basic type, these lightweight cylinders can now be mounted with our dual colour Series D-M9*W solid state auto switch at any point along the mounting grooves. The cushion needle, which is now placed in the top for easier accessibility, can be adjusted using a simple hexagon wrench.

For long strokes with compact size and an integrated guide, the MY1 series rodless actuator provides an ideal solution. The MY1 mechanical joint rodless cylinder includes four standard models, which allow the appropriate bearing style to be selected in order to match the accuracy and load requirements of your application. If necessary, you can also combine the basic MY1 cylinder with an external guide in order to create a special engineered solution. Piping options can be selected according to the application. MY1 is available in 9 bore sizes from 16mm to 100mm. Standard strokes are available up to 2000mm with a 5000mm long stroke option on some bore sizes.

The MY2 high precision guide cylinder is available in bore sizes 16mm, 25mm and 40mm. This series has been designed with a high precision single or double axis guide to create a compact, low profile cylinder. Maintenance has been simplified by allowing the cylinder to be detached without disturbing the guide unit and work piece.

Mechanically jointed rodless cylinder series MY3 provides high functionality with reduced height and length. The uniquely designed piston shape enables reduction of the height and length as well as practical arrangement of the common piping passages, cushion mechanism and positioning mechanism. This has achieved drastic miniaturization and weight reduction.

Thanks to its lightweight body and reduced length, our updated Series CY1S-Z magnetically coupled rodless cylinder now delivers improved performance. Weighing 15% less and up to 15mm shorter than previous models, the new CY1S-Z is ideal for applications where relatively light loads need to be moved at low or medium speeds and where space is at a premium. The design offers increased flexibility with a wide range of bilateral and central piping and stroke adjustment options. Thanks to the adjustment bolt, the stroke ends position can be maintained without the need for adjusting the stroke which delivers improved accuracy and repeatability. The auto switch mounting moves forward as the switches can be located in any position and a switch mounting rail is fitted as standard. The Series is highly durable as lub-retainers are mounted on the internal and external surfaces of the cylinder tube to maintain lubrication.

With no external leakage, the CY series can be used in many diverse environments. Magnetically coupled cylinders have a wide range of applications, and save mounting space. Loads and moments are possible through the use of integrated guides. A variety of guides can be used to achieve the necessary accuracy or allowable moment needed for your application. CY is available in 9 bore sizes, from 6mm to 63mm with standard stokes up to 1000mm. The 5 different model variations offer widest application choice. Auto switches are integrated as standard.

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
