About the Airtac SAID200 Double Rod Cylinder SAID200BX750S
The AirTAC SAID200X750-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric motion. Because a stainless SUS304 rod exits both end covers, the effective piston area is identical in each direction. This yields exactly 15079 N of force both extending and retracting at 0.5 MPa, eliminating speed and force mismatch.
Equipped with a -S magnet, the extruded aluminum barrel features dual sensor grooves for AirTAC CMSE reed and DMSE electronic switches. The rear rod extension is ideal for mounting a secondary cam, position flag, or driving a secondary mechanism, while providing superior anti-rotation guidance for heavy loads.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX750S Is Used
Symmetric Heavy Transfer
Drives large automotive or structural parts between stations with identical 15079 N force in both directions, preventing jerk during heavy load reversal.
Anti-Rotation Lifts
Lifts heavy platens without rotational drift, using the twin through-rods to maintain strict parallel guidance over the 750mm travel.
Dual-Side Tool Driving
Actuates a primary workpiece on the front rod while the rear rod simultaneously drives a secondary mechanism or position flag.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX750S the Right Cylinder?
Choose this 200mm bore when the 160mm class (9425 N at 0.5 MPa) lacks the thrust for your largest transfer stations. The twin-rod architecture is selected over a single-rod SAI when an application demands equal push-pull dynamics, dual-side guidance against rotation, or rear-rod position sensing. To mount position flags or secondary actuators, utilize the rear rod end.
At 750mm stroke, the extended SUS304 rod and heavy piston generate significant side-load and rod-bearing bending moments; always use an external linear guide to support the load. Note that air cushions only decelerate the piston near stroke end and do not hold position; if power loss drops the load, select a BSAID clamp-lock or SAIL locking cylinder. This cylinder is dimensionally interchangeable per ISO 15552 and uses PT tapered ports (G3/4). Mounting accessories are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID200BX750S FAQ
Because the rod occupies both sides of the piston, the extend and retract forces are equal. 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 SAID200X750-S is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile double-rod cylinders, using a PT G3/4 port and the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
