About the Airtac SAID50 Double Rod Cylinder SAID50AX220
The AirTAC SAID50X220 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 220 mm stroke. Because a rod extends from both end covers, the annulus area is identical on each side, yielding exactly 825 N of force in both extend and retract directions at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent push and pull dynamics.
Equipped with a SUS420J2 stainless steel rod (material code A), this variant provides enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific unit is supplied without a magnet. The rear rod end can simultaneously drive a secondary load or act as an anti-rotation guide.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX220 Is Used
Symmetric Force Transfer
Provides identical 825 N push and pull forces for transferring parts between two parallel workstations without needing pressure adjustments.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, ensuring precise linear guidance for heavy sliding carriage mechanisms.
Rear-End Sensing Mount
Allows mounting of a cam or physical position flag on the rear rod protrusion to trigger external mechanical limit switches.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX220 the Right Cylinder?
Select this 50 mm bore when an application demands equal 825 N bi-directional force at 0.5 MPa, bridging the gap between the smaller 40 mm (528 N) and larger 63 mm (1402 N) bores. A double-rod design is preferred over a single-rod SAI when you need twin-station actuation, dual-side guidance to prevent rotation, or a rear rod end to mount a position flag. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard double-rod profile cylinders.
For this 220 mm stroke configuration, the unit uses PT tapered ports sized G1/4 and supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke exceeds 300 mm is not met here, standard internal rod bearings handle the load adequately, but external guidance is always recommended for heavy lateral loads. Note that adjustable air cushions at both ends only decelerate the piston and do not hold the load if air pressure is lost.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID50 Double Rod Cylinder SAID50AX220 FAQ
The SAID50X220 generates 825 N of force in both the extend and retract directions at 0.5 MPa, and 1154 N at 0.7 MPa. Because it is a double-rod cylinder, the effective piston area is identical on both sides, making push and pull forces equal.
Yes, the SAID50X220 is dimensionally interchangeable per ISO 15552 and uses a standard profile barrel. It supports mounting accessories Basic, FA, LB, TC, FTC, TCM1, and TCM2, allowing it to serve as a direct drop-in replacement for other ISO 15552 double-rod profile cylinders.
