About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX270-100S
The AirTAC SAIJ63X270-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 1559 N pull force at 0.5 MPa and features a generous 100 mm adjustment range, creating a usable travel window of 170 to 270 mm for precise end-position tuning. The SUS420J2 stainless steel rod (option A) provides enhanced corrosion resistance, while the integrated magnet allows for direct mounting of CMSE reed or DMSE electronic sensors along the dual-side barrel grooves.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine setup or product changeover. The rear screw acts strictly as a travel stop to set deceleration limits and does not hold the load without live air pressure. It uses a PT tapered port thread and supports a speed range of 30 to 800 mm/s. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX270-100S Is Used
Variable End-Position Tuning
Dial in the exact retract distance between 170 and 270 mm during commissioning without swapping out the entire cylinder body.
Product Size Changeover
Quickly readjust the stroke stop on packaging lines to accommodate varying box lengths or product formats on the fly.
Machine Setup Calibration
Fine-tune the end-of-stroke stopping point to sync perfectly with downstream equipment, using the stopper screw rather than adding external shims.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX270-100S the Right Cylinder?
Choose this 63 mm bore when your application requires higher force than a 50 mm bore (which provides 825 N pull at 0.5 MPa) but does not need the bulk of an 80 mm bore (2268 N pull). The 100 mm adjustment window is ideal for equipment requiring variable end-stops across different product sizes, offering far more commissioning flexibility than a fixed-stroke SAI cylinder. For load-holding without continuous live air, this cylinder is not a lock; consider the SAIL or BSAI series, or an external pilot-operated check valve.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 270 mm nominal stroke, 100 mm adjustment, PT port, and the -S magnet requirement. Because the 270 mm stroke is relatively long, ensure external guiding is used to prevent excessive side-loading on the M16x1.5 rod thread, as the rear adjuster cannot compensate for off-axis loads.

- ✓ 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX270-100S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder exerts a push force of 1559 N and a pull force of 1402 N. At the maximum pressure of 1.0 MPa, it can deliver up to 318 kgf.
The rear adjuster screw allows you to shorten the effective travel from the 270 mm nominal stroke by up to 100 mm, giving a usable window of 170 to 270 mm. The adjuster functions only as a mechanical stop and does not lock or hold the load without continuous air pressure.
