About the Airtac SAID80 Double Rod Cylinder SAID80X750
The AirTAC SAID80X750 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80 mm bore and 750 mm stroke. Because the piston rod exits both end covers, the annular effective area is identical on extend and retract. This means push and pull forces are perfectly equal, delivering 2268 N each direction at 0.5 MPa and 3175 N at 0.7 MPa.
A standard carbon steel rod and PT tapered G3/8 port are equipped. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this unit ships without a magnet. The rear rod end is highly useful for mounting a secondary cam, position flag, or driving a secondary mechanism while keeping the load guided against rotation.

Where the Airtac SAID80 Double Rod Cylinder SAID80X750 Is Used
Symmetric Force Transfer
Drives a heavy workpiece where 2268 N of push and pull force must remain perfectly balanced, utilizing the twin-rod design to prevent asymmetric speed variations.
Anti-Rotation Slides
Keeps a precision sliding load guided and prevented from twisting over the 750 mm travel, using the dual rods exiting both ends for stable linear motion.
Through-Rod Sensing
Actuates a primary tool on the front rod while using the rear rod protrusion to trip a physical limit flag or cam for secondary timing verification.
Is the Airtac SAID80 Double Rod Cylinder SAID80X750 the Right Cylinder?
Choose this 80 mm bore when an application requires balanced 2268 N force both ways, stepping up from the 63 mm bore which provides 1402 N. A double-rod design is selected over a single-rod SAI when dual-side guidance, anti-rotation, or rear-rod sensing is required. Note that this cylinder does not hold its load when air is lost; if position holding is needed without live pressure, consider an SAIL lock, BSAID clamp-lock, or external pilot-operated check valve.
This SAID80X750 is dimensionally interchangeable per ISO 15552 for drop-in replacement. To match: 80 mm bore, 750 mm stroke, PT G3/8 port, and a mounting accessory from the SAID subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 750 mm, the long unsupported rod is prone to bending under side loads; always use an external guide rail to prevent rod-bearing damage.
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 SAID80 Double Rod Cylinder SAID80X750 FAQ
Because the rod occupies both sides of the piston, the effective area is the same in both directions. The SAID80X750 delivers an equal push and pull force of 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, it is a profile cylinder dimensionally interchangeable per ISO 15552. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR brackets found on single-rod variants.
