3-Position Cylinders
3-Position cylinders are used when three distinct rod positions are required from a single cylinder body. Two cylinders are assembled tip-to-tail with a common center head. Using cylinders with two different strokes (the shorter located on the rear cylinder), the front rod can extend from “home” to a positive mid-position or to full extension.
Back-to-Back Cylinders
Two cylinders are mounted back-to-back. They can have the same or different strokes and can operate independently. This assembly allows for four combinations of rods being extended or retracted.
Multi-Power® Cylinders (150 psi max)
Fabco-Air attaches multiple pistons to a common shaft and provides internal air passages through the shaft to all pistons. Internal baffles divide the cylinder body into separate sections or stages. When air pressure is applied to port #2, all pistons are pressurized simultaneously, nearly tripling the thrust. Cylinders can be built with up to four stages, allowing thrusts of over 16,000 pounds to be reached!
Tandem Cylinders
Tandem cylinders provide nearly twice the force compared to an equivalent double-acting cylinder. Two pistons are attached to a common piston rod. Ports 2 and 4 are pressurized simultaneously to nearly double the extend force. Ports 1 and 3 are pressurized to double the retract force.
Options
Option -E: Magnetic Piston
- Description: A magnet is bonded into the piston head. When the piston magnet moves past an external sensor, the magnetic field activates the sensor without physical contact.
- Reliability: The annular piston magnet is permanently bonded into a groove in the piston. It is a polarized permanent magnet of rubber-bonded barium ferrite that is very stable and unaffected by shock. Under normal usage, it will remain magnetized indefinitely.
- Warning: External magnetic fields and/or ferrous objects may affect the strength of the piston magnet, potentially impacting sensor actuation and piston position indication. Labels are affixed to the cylinder to warn users.
Male Rod Thread Stud: Option -MR
- Description: A high-strength stud is threaded into the female rod end and retained with thread-locking adhesive. This eliminates the small diameter thread relief typically required when machining male threads. The result is a much stronger rod end, which can be repaired rather than replaced if the stud becomes damaged. It is also available separately for individual installation. Available only with Style #3 or #8 Rod End.
Rubber Bumpers Options
-
Head -BF, Cap -BR, Head & Cap -BB
- Description: A donut or pad of rubber is bonded to act as the piston stop and absorb the impact of the piston. This reduces noise and absorbs energy.
- Effect on Cylinder Length: The cylinder length will increase by 0.062" per bumper to allow the piston to travel a minimum of the specified stroke.
- Operating Temperature: –20° to 220°F.
-
Notes:
- –BF is not available for 1-1/2" bore with oversize rod.
- –BF is not available for 1-1/2" bore with adjustable air cushion.
- –BF is not available for 2" bore with adjustable air cushion and oversize rod.
Silent Seal Bumpers: Option -SB
- Description: Attached to the piston, these bumpers reduce the noise caused by the piston impacting the end cap. Standard adjustable air cushions may be used in conjunction with these silent seal bumpers to further reduce noise and impact while providing deceleration benefits.
- Available Bores: 1-1/2" thru 8".
- Operating Temperature: –20° to 200°F.
- Operating Pressure: Up to 150 psi.
-
Notes:
- –SB is not available for 1-1/2" bore with oversize rod.
Additional Notes:
- Order Sensors, Sensor Clamps, and Cables Separately: For details, see page 13.
- Loctite™ and No Thread Relief: The use of high-strength adhesive and the lack of relief ensures that there are no weaknesses in the rod end for greater durability and strength.
