All moving components are designed for low friction. The use of self-lubricating rounded-lip seals and composite components yield low friction at zero leakage. Less friction results in less wear, so cycle life is maximized. Bores from 1-1/8" to 5" are called "sensor-ready" because they include a magnetic piston ring and integrated sensor grooves in the cylinder body as standard. Sensors drop in to these grooves for simple, inexpensive assembly and protection. The standard construction for 1-1/2" to 5" bores accommodates almost every NFPA mount as an accessory. Mountings that are factory-fitted to the cylinder are also available. The 3MA and 4MA are completely recyclable. Proven exterior toughness features include anodized aluminum endcaps and cylinder body; zinc-plated endcap fasteners; outboard "molythane" rod wiper and case-hardened, hard chrome-plated piston rods. Stainless steel piston rods and fasteners are available.
