About the Airtac SAID200 Double Rod Cylinder SAID200BX160
The AirTAC SAID200X160 is a double-acting, double-rod profile cylinder built to ISO 15552 mounting dimensions. A single piston drives a rod out of both end covers, yielding equal push and pull forces. It generates 15079 N of thrust in each direction at 0.5 MPa and 21110 N at 0.7 MPa, operating at speeds of 30-500 mm/s.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of position switches. Because the rear rod protrudes beyond the back cover, you must account for additional clearance when designing your machine envelope.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX160 Is Used
Symmetric Press Drive
Drives a large forming press with equal extend and retract forces, ensuring consistent bidirectional pressure for heavy stamping operations.
Twin-Station Transfer
Actuates a dual-sided material transfer carriage where the rear rod simultaneously pushes a secondary mechanism or limit flag.
Anti-Rotation Lift
Lifts heavy industrial platens while the through-rod geometry prevents the load from twisting or drifting off-center during vertical travel.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX160 the Right Cylinder?
Select this 200 mm bore when an application requires immense bidirectional force that a smaller bore cannot provide, or step down to a 160 mm bore if you need to reduce physical mass while still achieving 9425 N at 0.5 MPa. The twin-rod architecture is chosen over a single-rod SAI when the mechanism demands dual-side guidance to prevent rotation, or when a rear rod end is needed to mount a cam or position flag. Mounting accessories available include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
For this 160 mm stroke, the 40 mm diameter rod and M36x2 thread provide high structural rigidity, but long unsupported loads still require an external guide to prevent rod-bearing bending. Note that this cylinder relies on adjustable air cushions at both ends to decelerate the piston near stroke end; it does not hold a load if air pressure is lost. For true position holding without live pressure, consider an external rod lock or a BSAID clamp-lock cylinder.
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 SAID200 Double Rod Cylinder SAID200BX160 FAQ
Because the rod area is subtracted on both sides, the push and pull forces are equal. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa in both directions.
Yes, the SAID200X200 is dimensionally interchangeable per ISO 15552 profile cylinder standards. It shares the same mounting footprint and can serve as a drop-in replacement for other ISO 15552 double-rod cylinders.
