About the Airtac SAID50 Double Rod Cylinder SAID50BX600
The AirTAC SAID50X600 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 600 mm stroke. Because a stainless steel rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 825 N of force in both directions at 0.5 MPa. This SUS304 (code B) rod construction provides excellent corrosion resistance for demanding environments.
The twin-rod architecture allows you to mount the primary workpiece on one end while attaching a position flag, cam, or secondary mechanism to the rear rod. Dual-side guidance significantly improves anti-rotation stability compared to a single-rod SAI. The extruded aluminum barrel includes sensor grooves on both sides for straightforward CMSE or DMSE switch installation.

Where the Airtac SAID50 Double Rod Cylinder SAID50BX600 Is Used
Symmetric Force Transfer
Drives push and pull mechanisms requiring identical 825 N force and speed in both directions without needing flow controls to balance motion.
Anti-Rotation Slides
Uses the twin-rod geometry to prevent piston rotation during 600 mm travel, ensuring precise linear guidance for machining fixtures.
Rear-Rod Sensing
Mounts a CMSE or DMSE position flag on the protruding rear rod end to trigger external sequencing valves away from the primary work area.
Is the Airtac SAID50 Double Rod Cylinder SAID50BX600 the Right Cylinder?
Select this 50 mm bore model when your application requires 825 N of symmetric force at 0.5 MPa, or 1154 N at 0.7 MPa. If your mechanism needs less force, stepping down to the 40 mm bore yields 528 N both ways; for heavier loads, the 63 mm bore provides 1402 N. The 600 mm stroke is a standard length, but at this extended travel, the 20 mm rod faces increased bending moments and side-load risks. You must use an external guide to prevent rod-bearing wear.
Choose the SAID double-rod over a single-rod SAI when you need dual-side guidance, anti-rotation control, or rear-rod sensing. Note that a plain SAID does not hold its load when air is removed or exhausted; the piston drifts without pressure. For position holding without live air, consider the SAIL (air-released lock) or BSAID (clamp-lock) variants. This cylinder uses a PT G1/4 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting the FB, CA, CB, and CR options.

- ✓ 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 SAID50 Double Rod Cylinder SAID50BX600 FAQ
Because the double-rod design occupies space on both sides of the piston, the effective area is equal for extend and retract. It outputs 825 N both ways at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
Yes, it is a profile cylinder built to ISO 15552 mounting interface dimensions, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It uses the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set.
