• Bore Size: 4 (in)
• Stroke: 21 (in)
• Working Fluid: Air
• Operating Pressure Range: 15 to 250 PSI
• Lubrification: Not required
• Temperature Range: -45 to 110 °C
• Please add suffix «.01» to order these cylinders with a magnetized piston for usage with a magnetic proximity switch (example: 81.522.01)
Material(s):
• Wiper: Keeps dirt out for less maintenance and longer service life of the cylinder (urethane) (temperature: -45 to 110 °C)
• Rod Lips Seal: Designed with a real rod u-cup; completely self-compensating for zero leakage at all pressures
• Tie Rods: Corrosion resistant (nitrocarburation), stressproof steel maintains uniform compression on tube end seals
• 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 Aluminum bar stock. Offers long bearing support
• Solid Aluminum Head & Cap: Machined from solid one-piece Aluminum bar stock and black anodized for corrosion resistance
• Piston Rod: Medium carbon steel, chrome plated and polished. Two wrench flats are provided for rod end attachment
• Rod Gland: Bronze gland is removable without cylinder disassembly for easy maintenance. Designed to provide maximum rod bearing service life
• Hard Anodized Aluminum Tube: Provides superior wear resistance and lower friction coefficient for maximum seal service life
• 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)
• 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
• O-Ring Tube End Seals: Nitrile O-ring design is pressure compensating and reusable
• Meet NFPA standards
• NFPA-MS4 standard mounting styles
• Made of corrosion-resistant Aluminum
• Adjustable cushions on both ends
• High strength
Options available:
• Magnetic piston
• Proximity switches
• High temperature seals
• Stainless steel 304 or 316 piston rod and tie rods
PUSH-PULL FORCES
• Cylinders provide specific forces based on the piston area and on pressure provided.
• 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.
• TOPRING air cylinders are intended for use in industrial compressed air systems only
• They must not be used where pressure or temperature may exceed maximum rated operating conditions
• In lubricated applications, some oil mist may escape from the point of use into the surrounding atmosphere
• Selecting the proper cylinder for the application remains the responsability of the system designer; these forces should be used as a guideline and should not replace testing of the specific application
• Selecting the proper cylinder for the application remains the responsibility of the system designer; these forces should be used as a guideline and it is important to do the required tests according to the specific application.
