SMC’s CG5 Actuator Offers Superior Moisture Resistance in Wash-Down Applications
Tustin, CA – SMC Corporation, the world’s largest manufacturer of pneumatic automation products, has announced the introduction of the Series CG5 stainless steel pneumatically driven linear actuator. The CG5 is designed specifically for superior moisture and corrosion resistance and uses FDA (Food and Drug Administration) approved grease and materials which are suitable for applications such as medical product manufacturing, medical packaging, dairy, bakery, filling/bottling, meatpacking, food packaging, and food handling.

SMC manufactures the external parts of the CG5 with SUS304 stainless steel so as to be compatible with foodstuffs, sterilizing solutions, dyestuffs, and a variety of organic and inorganic chemicals. Several features of the CG5 actuator help eliminate debris build up: mounting brackets are electro-polished to create the smoothest surface possible, end caps are screwed on rather than crimped to provide a smooth profile, and metal plugs are supplied to prevent residue accumulation in unused mounting threads.

The CG5 actuator uses a special rod scraper that minimizes water infiltration to the rod seals. Compared to standard actuators, this increases the service life by an average of ten times. For even greater service life, the cylinder can be disassembled for easy seal replacement.

Nitrile Rubber (NBR) or Fluoro Rubber (FKM) seals are available; Nitrile has high abrasion and petroleum-based fluid resistance; Fluoro has high chlorine and sulpher resistance.

The CG5 has a maximum operating pressure of 1.0 MPa and is available in 8 bore sizes ranging from 20 to 100mm with Imperial or Metric rod end/ports. Bore sizes 20-63mm, have a piston speed of 50-1000 mm/s; bore sizes 80 and 100mm have a piston speed of 50-700 mm/s. Band mount auto switches with IP67 watertight construction and red/green LED operating position indicator are available. The ambient/fluid temperature ranges for the CG5 are -10 to 70 deg. c without the auto switch, and -10 to 60 deg. c with. Adjustable air cushions and rubber bumpers are both standard options.

Michael Fallon, Actuator Product Manager for SMC, says “The CG5 series actuator is a unique and very cost effective solution for applications that require excellent corrosion resistance or wash-down capability. Before SMC introduced the CG5, designers with applications requiring wash-down capability or corrosion resistance were often forced to specify bulky and expensive tie-rod cylinders never originally designed for these applications.”

The CG5 pneumatically driven linear actuator is manufactured in the USA by SMC Corporation, with a full selection of accessories and mounting brackets available.

SMC Corporation manufactures high quality actuators and cylinders, airline and air preparation equipment, high-purity products, instrumentation, and a host of fittings and accessories applicable to the pneumatic automation industry. SMC has a total of 14 production facilities, 3 of which are in North America –California, Indiana, and Ontario, Canada. SMC’s global presence allows them to provide quality customer service in any part of the world.
