Other Details
Adjustable cushions on both ends
Bore Size: 3-1/4 (in)
Check Seal Cushion and Needle valves: Precision cushion spuds combine with a new style of floating cushion seal to provide smooth deceleration at end of stroke. Needle valves make adjustments easy
Cylinders provide specific forces based on the piston area and on pressure provided.
Hard Anodized Aluminium Tube: Provides superior wear resistance and lower friction coefficient for maximum seal service life
High strengthOptions available:
High temperature seals
Lubrification: Not required
Made of corrosion-resistant Aluminium
Magnetic piston
Meet NFPA standards
NFPA-MS4 standard mounting styles
O-Ring Tube End Seals: Nitrile O-ring design is pressure compensating and reusable
Operating Pressure Range: 15 to 250 PSI
Piston Rod: Medium carbon steel, chrome plated and polished. Two wrench flats are provided for rod end attachment
Piston Seals: Lip-type low friction Urethane piston seals are pressure energized and wear compensating for low friction and long service life (-45 to 110 °C)
Piston Wear Ring: Made from nylon to reduce friction and to ensure maximum service life in side load applications. Eliminates metal-to-metal contact
Piston: Machined from solid one-piece aluminium bar stock. Offers long bearing support
Please add suffix «.01» to order these cylinders with a magnetized piston for usage with a magnetic proximity switch (example: 81.522.01)
Proximity switches
Rod Gland: Bronze gland is removable without cylinder disassembly for easy maintenance. Designed to provide maximum rod bearing service life
Rod Lips Seal: Designed with a real rod u-cup; completely self-compensating for zero leakage at all pressures
Solid Aluminium Head & Cap: Machined from solid one-piece aluminium bar stock and black anodized for corrosion resistance
Stainless steel 304 or 316 piston rod and tie rodsPUSH-PULL FORCES
Stroke: 20 (in)
Temperature Range: -45 to 110 °C
These forces will not be the same for push and pull, since the rod takes up a portion of the area of the piston when pulling.
Tie Rods: (nitrocarburation), stressproof steel maintains uniform compression on tube end seals
Wiper: Keeps dirt out for less maintenance and longer service life of the cylinder (urethane) (temperature: -45 to 110 °C)
Working Fluid: Air
