About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-75S
The AirTAC SAIJ100X160-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 85-160 mm. It delivers a robust 5497 N push force at 0.7 MPa, making it well-suited for heavy-duty positioning tasks. This variant includes a SUS420J2 stainless steel rod (material code A) and PT tapered port threads.
Equipped with a magnet for CMSE reed and DMSE electronic sensors, it integrates seamlessly into automated tracking systems. The extruded aluminum barrel provides standard ISO 15552 mounting dimensions, while the rear stopper screw lets you dial in the exact end-position at commissioning without adding external physical stops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-75S Is Used
Machine Changeover
Dial in the 85-160 mm travel window during product size transitions on a packaging line without physically swapping cylinders.
End-Position Tuning
Fine-tune the retract stopper at machine commissioning to achieve exact end-of-stroke positioning for critical assembly tasks.
Heavy-Duty Positioning
Leverage the 5497 N push force at 0.7 MPa to move substantial jigs or fixtures while retaining adjustable travel limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-75S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires significant thrust, such as the 3927 N push force at 0.5 MPa, but demands on-site travel adjustments to accommodate varying product sizes. The generous 75 mm adjustment window is ideal for machinery changeover, replacing the need to physically swap out a fixed-stroke SAI cylinder. Because the stroke is 160 mm, side-load risks are minimal, but always ensure standard alignment to prevent premature seal wear.
When specifying a replacement, match the 100 mm bore, 160 mm nominal stroke, 75 mm adjuster, PT ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series instead. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ100AX160-75S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.7 MPa, the push force increases to 5497 N, and it reaches a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 160 mm stroke by up to 75 mm, creating a usable travel window of 85 to 160 mm. This stopper sets the travel end and deceleration but does not lock the load without live air pressure.
