About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-40
The AirTAC SAIJ80X750-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 710 to 750 mm usable travel window, allowing you to dial back the nominal 750 mm stroke by up to 40 mm during commissioning without adding external stops. The 80 mm bore generates a substantial 4523 N of push force at 0.9 MPa, making it well-suited for heavy positioning tasks.
This variant uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. It features PT tapered port threads (G3/8) and reaches speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed and DMSE electronic sensors if a magnet is added later.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-40 Is Used
Machine Changeover
Fine-tune the 710-750 mm retract position on the fly during product size changeovers without disassembling the actuator or adding external mechanical stops.
Heavy Material Positioning
Leverage the 4523 N push force at 0.9 MPa to move heavy pallets or workpieces into exact machining stations along a long-stroke conveyor line.
End-Stop Calibration
Dial in the exact end-of-stroke position during machine setup to compensate for mechanical wear or slight variations in fixture dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-40 the Right Cylinder?
Choose this 80 mm bore when your application requires high thrust—stepping down to the 63 mm bore drops the 0.9 MPa push force to 2805 N, while stepping up to the 100 mm bore increases it to 7068 N. The adjustable rear stopper is ideal for product changeovers on automated lines, letting you fine-tune the retract end-position without swapping the cylinder. Because the 750 mm stroke is non-standard and exceeds typical guide lengths, an external guide is strongly recommended to handle side loads and prevent rod binding.
When specifying a replacement, ensure it matches the 80 mm bore, 750 mm stroke, 40 mm adjustment range, PT port threads, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.
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 SAIJ80 Adjustable Cylinder SAIJ80AX750-40 FAQ
At an operating pressure of 0.9 MPa, this 80 mm bore cylinder generates a push force of 4523 N and a pull force of 3681 N. The maximum thrust is 513 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 750 mm down to as little as 710 mm. It decelerates the travel end but does not lock the load; live air pressure is still required to hold position.
