About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-30S
The AirTAC SAIJ100X170-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 140 to 170 mm, allowing you to dial back the end position by up to 30 mm during commissioning. This bore delivers 5497 N of push force at 0.7 MPa, making it suited for heavier actuation tasks.
This variant includes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and features a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the unit uses PT tapered G1/2 ports.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-30S Is Used
Machine Changeover
Quickly fine-tune the 140-170 mm stroke window during product size transitions on a packaging line without bolting on external stops.
Variable End Positioning
Dial in the exact retraction point for heavy press operations, utilizing the 5497 N push force at 0.7 MPa with precise end-stop tuning.
Assembly Station Tuning
Adjust the effective travel on automated assembly fixtures to accommodate varying part heights, relying on the robust SUS420J2 stainless rod.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-30S the Right Cylinder?
Choose this 100 mm bore when you need more thrust than the 80 mm version (which provides 3518 N at 0.7 MPa) but want to avoid the larger footprint of a 125 mm cylinder. The adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers without swapping out the entire actuator. To match this ISO 15552 cylinder, confirm the 100 mm bore, 170 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet option.
Since the nominal stroke is 170 mm, an external guide is recommended to manage side loads on the extended rod. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
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 SAIJ100AX170-30S FAQ
The rear adjuster screw lets you shorten the effective travel by up to 30 mm, creating a 140 to 170 mm usable window. It acts as a mechanical stop to decelerate the load and set the end position, but it is not a lock and will not hold the load without live air pressure.
At a standard 0.7 MPa operating pressure, the SAIJ100X170-30-S generates 5497 N of push force and 5146 N of pull force. It can deliver up to 7068 N of push force at the maximum 0.9 MPa pressure.
