About the Airtac SAID200 Double Rod Cylinder SAID200X250
The AirTAC SAID200X250 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. A single piston drives a carbon steel rod out of both end covers, yielding perfectly balanced thrust. Because the annulus area is identical on both sides, it generates 15079 N of force in both extend and retract directions at 0.5 MPa.
This through-rod architecture allows you to mount the primary workpiece on the front end and a position flag or secondary cam on the rear. The extruded aluminum barrel features sensor grooves on both sides, though this unit lacks the -S magnet. For elevated thermal demands, seal options include Viton H, and the BSAID variant offers a clamp-lock if static holding is required.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID200 Double Rod Cylinder SAID200X250 Is Used
Heavy-Duty Anti-Rotation Slide
The twin-rod design inherently resists torsional twisting, guiding heavy stamping dies or press platens with strict parallelism and zero rotational drift.
Symmetric Force Transfer
Provides exactly 15079 N of thrust and pull at 0.5 MPa, driving identical clamping pressure on both strokes for balanced heavy-load manipulation.
Dual-Station Actuation
Mounts a primary tool on the front rod end and a secondary mechanism or limit flag on the rear protruding rod to sequence two machinery actions simultaneously.
Is the Airtac SAID200 Double Rod Cylinder SAID200X250 the Right Cylinder?
Selecting this 200 mm bore is appropriate when an application demands massive equal bidirectional force that a single-rod SAI cannot provide. If 15079 N is excessive, stepping down to the 160 mm bore drops the output to 9425 N at 0.5 MPa. The SAID200X250 uses a G3/4 PT port and supports mounting accessories Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR styles found on single-rod models.
Because the stroke is 250 mm, the 40 mm rod and M36x2 thread experience leveraged bending stresses under lateral loads; an external guide rail is strongly recommended to prevent premature rod-bearing wear. Note that standard air cushions only decelerate the piston near stroke end and will not hold a load if air pressure drops.
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 SAID200X250 FAQ
Because the rod exits both ends, the effective piston area is identical in both directions. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552 mounting dimensions. You can drop it in for other ISO 15552 double-rod profile cylinders, using the standard Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting accessories.
