About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-30S
The AirTAC SAIJ63X150-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 120 to 150 mm. It delivers a robust 1559 Newtons of pull force at 0.5 MPa, making it ideal for mid-range actuation tasks. The barrel features an extruded aluminum design with sensor grooves on both sides.
This variant includes a magnet (-S) for position detection and utilizes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance. The rear adjustment screw allows you to fine-tune the retract end position at commissioning without adding external stops. The adjuster acts purely as a travel stop, so live air is required to maintain the load.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-30S Is Used
Machine Changeover
Quickly reconfigure the 120-150 mm stroke end-stop when switching product sizes on a packaging line, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the retract position during commissioning to align tooling perfectly, absorbing minor mechanical variances.
Variable Diverter Stops
Adjust the stopping distance on the fly for different pallet sizes without bolting on external hard stops.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-30S the Right Cylinder?
Choose this 63 mm bore when you need more force than a 50 mm cylinder (which provides 825 N pull at 0.5 MPa) but want a more compact footprint than an 80 mm option. The adjustable 120-150 mm window is perfect for product changeovers on a packaging line, letting you dial in the exact end-stop mechanically rather than swapping cylinders. For position feedback, the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 150 mm nominal stroke, PT tapered port threads, and the -S magnet requirement. Because the nominal stroke is 150 mm, side-loading is minimal, but always ensure the M16x1.5 rod thread is aligned with the load guide. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. If you need true load-holding without air pressure, consider the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-30S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of pull force and 2182 N of push force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, creating a 120-150 mm usable travel window. It functions as a mechanical stop and does not lock the load without live air.
