About the Airtac SAID200 Double Rod Cylinder SAID200BX210S
The AirTAC SAID200X210-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding an equal force of 15079 N each way at 0.5 MPa. This through-rod geometry provides superior anti-rotation stability and allows a secondary mechanism or position flag to be driven from the rear.
Equipped with a magnetic piston (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, this 200 mm bore unit features a robust 40 mm SUS304 stainless steel rod (code B) for superior corrosion resistance. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to decelerate massive loads smoothly within its 30-500 mm/s speed range.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX210S Is Used
Symmetric Pressing
Ideal for heavy stamping or pressing stations requiring identical push and pull forces, utilizing the 15079 N bidirectional output to maintain consistent pressure on return strokes.
Twin-Station Transfer
Drives two synchronized workstations simultaneously by mounting tooling on the front rod end and a cam or linkage on the rear through-rod, ensuring perfectly matched motion.
Anti-Rotation Guidance
The dual 40 mm SUS304 rods provide high torsional rigidity, preventing load rotation during vertical lifting or heavy-load transfer without relying solely on external guides.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX210S the Right Cylinder?
Select this 200 mm bore model when an application demands immense bidirectional force that a single-rod SAI cannot provide symmetrically; if lower force is acceptable, stepping down to the 160 mm bore yields 9425 N each way at 0.5 MPa. The SAID mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found on single-rod counterparts. It serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 double-rod cylinders.
At a 210 mm stroke, the 40 mm rod requires substantial lateral support to prevent rod-bearing bending under heavy loads, making an external guide rail essential. Note that a plain SAID does not hold its position if air pressure is lost; for dead-air load holding, consider an BSAID clamp-lock variant or an external pilot-operated check valve. Ensure adequate rear-rod clearance in your machine design, as the through-rod protrudes beyond the rear cover.

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 SAID200BX210S FAQ
Because it is a double-rod cylinder, the force is identical in both directions due to equal annulus areas. It provides 15079 N both ways at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X210-S is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses PT tapered ports and supports CMSE/DMSE sensors.
