About the Airtac SAID200 Double Rod Cylinder SAID200BX225S
The AirTAC SAID200X225-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 225 mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding equal force and speed both ways. You get 15079 N of thrust and pull at 0.5 MPa, climbing to 27141 N at 0.9 MPa. This genuine AirTAC unit uses a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet for position sensing.
Equipped with -S magnet compatibility, it works seamlessly with AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves. The rear rod protrusion allows you to mount a cam or position flag opposite the primary workload, providing dual-side guidance and excellent anti-rotation stability. Fluid must be filtered to 40 um, operating within a -20 to +70 C range and 0.15-1.0 MPa pressure.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX225S Is Used
Symmetric Stamping
Drives a heavy press die with equal push and pull force, preventing asymmetric wear on the tooling during bidirectional metal forming.
Twin-Station Transfer
Actuates two linked workstations simultaneously by mounting tooling on the front rod and a synchronized drive link on the rear rod.
Anti-Rotation Guidance
Keeps heavy sliding gates perfectly aligned without rotational drift by using the dual-rod structure as an inherent linear guide.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX225S the Right Cylinder?
Select this 200 mm bore when you need massive bidirectional force that a single-rod SAI cannot provide symmetrically. If your application requires less force, stepping down to a 160 mm bore offers 9425 N at 0.5 MPa. The SAID200X225-S uses PT G3/4 ports and a 50 mm adjustable air cushion at both ends to decelerate heavy loads. Note that air cushions only slow the piston near stroke end; they do not hold the load. If position holding without live pressure is required, consider a SAIL lock, BSAID clamp-lock, or an external pilot-operated check valve.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. Available mounting accessories include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Since the stroke is 225 mm, side-load and rod-bearing bending risks are moderate; use an external guide to support long unsupported loads. The M36x2 rod thread provides a robust interface for heavy tooling.

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 SAID200BX225S FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers 15079 N of force in both extend and retract directions at 0.5 MPa, and 27141 N at 0.9 MPa.
Yes. The SAID200X225-S is an ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a standard mounting interface but omits FB, CA, CB, and CR brackets.
