About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-20S
The AirTAC SAIJ100X160-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 160 mm nominal travel by up to 20 mm for a precise 140-160 mm usable window. This built-in fine-tuning simplifies product changeovers without swapping hardware. It delivers robust thrust, pushing 5497 N at 0.7 MPa and pulling 3681 N.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the PT tapered port threads ensure a tight pneumatic seal.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-20S Is Used
Precision Press Fit
Dial in the exact 140-160 mm insertion depth during automated assembly to prevent part damage without changing the cylinder.
Product Changeover
Quickly adjust the rear stopper to accommodate different material thicknesses on a packaging line, reducing machine setup downtime.
Heavy Material Handling
Leverage the 5497 N push force at 0.7 MPa to move dense workpieces while fine-tuning the end position on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-20S the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust that smaller neighbors cannot provide, such as the 80 mm bore which yields 3518 N push at 0.7 MPa. The adjustable end-stop is ideal for variable end positions, whereas a fixed SAI cylinder suits static stops. For mounting, SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, deliberately omitting FB, CA, CB, and CR options.
Because the stroke is 160 mm, side-load risks are moderate, but external guides are recommended for heavy off-center loads. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an external rod lock or the BSAI clamp-lock series.
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 SAIJ100AX160-20S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. At 0.5 MPa, the push force is 3927 N.
The rear adjuster screw lets you shorten the 160 mm nominal stroke by up to 20 mm, creating a usable travel window of 140 to 160 mm. It functions as a mechanical stop to fine-tune the end position and is not a locking device.
