About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-50S
The AirTAC SAIJ100X160-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 110-160 mm usable travel window, allowing you to trim the 160 mm nominal stroke by up to 50 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads while utilizing a PT tapered G1/2 port.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, and the adjustable rear stopper acts purely as a travel limit, not a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-50S Is Used
Product Changeover
Dial in the 110-160 mm travel window during line changeovers to accommodate different product sizes without mechanical rebuilds.
End-Stop Tuning
Fine-tune the retract position at commissioning using the rear screw, ensuring precise alignment without adding external stops.
Heavy Forming
Leverage the 3927 N push force at 0.5 MPa for pressing or forming tasks that require adjustable end positions for varying material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-50S the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust, such as the 3927 N push or 3681 N pull force at 0.5 MPa. If your application requires less force and a smaller footprint, stepping down to an 80 mm bore yields 2513 N push force. The 50 mm adjustment range is ideal for product changeovers, letting you fine-tune the end position without swapping cylinders or adding external stops.
Because the 160 mm stroke is under the 300 mm side-load threshold, the robust 25 mm rod handles standard loads well, though unsupported loads still require external guiding. To replace an ISO 15552 cylinder, match the 100 mm bore, 160 mm stroke, 50 mm adjuster, PT G1/2 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live air, select a SAIL or BSAI cylinder instead.
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 SAIJ100 Adjustable Cylinder SAIJ100AX160-50S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjuster screw allows you to shorten the 160 mm nominal stroke by up to 50 mm, creating a usable travel window of 110-160 mm. This stopper sets the end position but does not lock or hold the load without continuous air pressure.
