Pneumatic mill-duty cylinders - EM 02 series

Eaton mill-duty pneumatic EM 02 series cylinders are engineered to meet the extreme demands of primary metal applications. They’re ideal in arc furnaces, slab casters, rolling mills and coating lines. If we don’t have the bore size or stroke length you need, we can customize a solution for you.

Made to last

Accelerate cycle times and increase production

Maximize acceleration with our patented floating ring cushion seal, or alternate ball check design. Optimize deceleration with the fully adjustable cushioning system.


Our standard pneumatic tubes are honed and chrome-plated to a minimum of 0.0006 in diametrically. Need heavier plating on pneumatic bores? We can do that.

Safe, dependable performance

Captive screws prevent accidental removal, while still allowing easy adjustment. The SureSeal system—the connection between rod and wipers—ensures exceptional performance and durability. Pneumatic cylinders use a high-quality nitrile U-cup rod seal and double-lipped wiper.

Minimize wear and extend seal life

Special wear bands eliminate metal-to-metal contact for longer cylinder life and increased load-carrying capability. The case-hardened, chrome-plated piston rod ensures maximum durability and seal life, resulting in less downtime.
