About the Airtac SAID50 Double Rod Cylinder SAID50X200
The AirTAC SAID50X200 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 200mm stroke. Because a carbon steel rod exits both end covers, the annulus areas are identical, yielding equal extend and retract forces of 825N at 0.5MPa.
This through-rod design allows mounting a primary workpiece on the front and a position flag or cam on the rear for dual-side guidance. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later.

Where the Airtac SAID50 Double Rod Cylinder SAID50X200 Is Used
Symmetric Force Transfer
Drives a transfer carriage with identical push and pull thrust, ensuring consistent acceleration and deceleration without momentum shifts.
Anti-Rotation Slides
Twin rods prevent the piston from twisting under offset loads, maintaining precise linear guidance for sliding mechanisms.
Rear-Cam Actuation
The protruding rear rod drives a secondary cam or limit flag, allowing dual-side machine sequencing from one cylinder.
Is the Airtac SAID50 Double Rod Cylinder SAID50X200 the Right Cylinder?
Choose this 50mm bore when an application demands anti-rotation guidance or symmetric twin-station actuation that a single-rod SAI cannot provide. If your mechanism needs less force, step down to the 40mm bore (528N both ways); if you need more thrust, step up to the 63mm bore (1402N both ways).
This model uses a PT G1/4 port and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding is required without live air pressure, consider a SAIL or BSAID variant. Since the stroke is 200mm, external guides are recommended to prevent rod-bearing bending under side loads.
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 SAID50X200 FAQ
The SAID50X200 provides equal force in both directions due to its double-rod design. It delivers 825N at 0.5MPa, 1154N at 0.7MPa, and 1484N at 0.9MPa for both extension and retraction.
Yes, the SAID50X200 is dimensionally interchangeable per ISO 15552 profile cylinder standards. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, using the standard mounting interface.
