About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX75-10
The AirTAC SAIJ80X75-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a precise 65-75 mm usable stroke window, letting you dial in the retract end-position at commissioning without adding external stops. It delivers a robust 2513 N push force at 0.5 MPa, making it suitable for medium-duty positioning tasks.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and comes with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a speed range of 30-800 mm/s and uses a variable air cushion at both ends to decelerate the load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX75-10 Is Used
Machine Setup & Changeover
Dial in the exact retract distance within the 65-75 mm window during product size changeovers without swapping the physical cylinder.
End-Stop Tuning
Fine-tune the final resting position of tooling by up to 10 mm at commissioning, eliminating the need to bolt on external mechanical stops.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for medium-force positioning tasks in environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX75-10 the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) is too weak, but a 100 mm bore (3927 N) would be excessive overkill. The 10 mm adjustable window is ideal for machine setups requiring variable end-stops during product changeovers, rather than relying on a fixed-stroke SAI cylinder. For any application needing 300 mm or more of stroke, you should add an external guide to manage side loads, though this 75 mm travel is well within safe rod limits.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. If your setup requires true fail-safe load holding, consider the SAIL or BSAI series instead. This cylinder is dimensionally interchangeable per ISO 15552, with a G3/8 port, PT threads, and a mounting set limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX75-10 FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 10 mm, providing a usable travel window of 65 to 75 mm. The adjuster acts as a physical stop to set the end position and does not lock the load without air pressure.
