SMC HYG hygienic cylinders

The hygienic cylinder from SMC’s HYG range uses guided rod cylinders and offers high performance when used in machine applications, especially where hygiene needs to be considered. The guided cylinders offer high lateral load resistance; smooth surfaces to enable easy cleaning; increased auto switch mounting rail options; and improved water resistance — up to 10 times greater than other products on the market.

Improved water resistance is achieved by various socket, seal and scraper options, with optional NBR or FKM seals/scrapers on guide and piston rods (NBR for normal environments and environments with water spray/splashes, FKM for environments with chemical spray/splashes). The cylinders can also operate with a choice of lubrication grease: standard grease for normal environments without spray water or food-safe grease (NSF-H1) for environments with water and chemicals.

A special coating is applied to the piston rod guide (PAT) and, with cleverly designed air relief ports on the guide, the released air is outside of the spray water environment. Due to the design of the cylinder, mounting is possible in three positions: from the top, side or from underneath. Plug bolts are used to simply close the mounting holes not used.

In high-performance machines, the innovative design of the cylinders ensures fault-free and safe production. The product also offers function integration and water-penetration protection in a hygienic, cleaner-friendly design.
