About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX950-100
The AirTAC SAIJ80X950-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an effective travel window of 850 to 950 mm. Delivering 2513 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
The integrated rear stopper screw allows you to fine-tune the retract end-position at commissioning without adding external stops or swapping the cylinder. It utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX950-100 Is Used
Variable End-Stop Tuning
Dial in the exact 850 to 950 mm retract position during machine setup without machining custom spacers or changing the cylinder.
Product Changeover
Quickly adapt the retract distance on a packaging line when handling different carton sizes, using the 100 mm adjustment range to switch formats.
Long-Stroke Assembly
Control the final approach of a 950 mm stroke assembly process, using the rear stopper to set the precise end-position for a delicate pressing operation.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX950-100 the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust but not the full 4523 N push force of the 100 mm bore at 0.9 MPa. The 100 mm adjustment range is ideal for product changeovers on a line where the exact retract distance varies, providing a wide tuning window versus a fixed-stroke SAI cylinder.
For a drop-in ISO 15552 replacement, match the 80 mm bore, 950 mm stroke, 100 mm adjustment, PT ports, and SUS304 (B) rod material. Because the stroke is 950 mm, the 25 mm rod should be guided externally to prevent sagging and excessive side-load. Note that the rear adjuster is a travel stop, not a lock; it will not hold the load without live air pressure, so use a SAIL or BSAI cylinder if fail-safe holding is required.
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 SAIJ80BX950-100 FAQ
At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. The operating speed range is 30-800 mm/s, and it features a 36 mm cushion at both ends to decelerate the load.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 950 mm nominal stroke by up to 100 mm, creating an adjustable travel window of 850 to 950 mm. It only sets the end-position and does not lock the load without continuous air pressure.
