About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-50S
The AirTAC SAIJ100X170-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 170 mm stroke that can be dialed back by up to 50 mm, giving you a precise 120-170 mm usable travel window during commissioning. Delivering 5497 N of push force at 0.7 MPa, it handles heavy loads while allowing fine end-position tuning without swapping out the entire unit.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the G1/2 port handles the necessary air volume for its 30-800 mm/s operating speed.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-50S Is Used
Variable End-Stop Forming
Dial in the 120-170 mm stroke window to accommodate different material thicknesses in metal forming presses without changing the cylinder.
Product Size Changeover
Quickly adjust the retract end position by up to 50 mm during packaging line format changes to handle varying box dimensions on the fly.
Heavy Clamp Positioning
Leverage the 5497 N push force at 0.7 MPa to secure heavy workpieces, using the rear stopper to fine-tune the exact clamping depth at setup.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-50S the Right Cylinder?
Select this 100 mm bore when a 63 mm bore (2182 N push at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N push at 0.5 MPa) leaves no margin. The 50 mm adjustment range is ideal for product changeovers on a line, allowing you to shift the end-stop dynamically rather than installing fixed external stops. For mounting, SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting FB, CA, CB, and CR options.
Remember that the rear adjuster acts only as a travel stop to decelerate the load alongside the air cushion; it does not hold the load without live air. For position holding without pneumatic pressure, consider an external rod lock or AirTAC SAIL/BSAI variants. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 170 mm stroke, 50 mm adjustment, PT tapered ports, SUS420J2 rod, and the -S magnet.
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 SAIJ100AX170-50S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 5145 N of pull force. At 0.5 MPa, it delivers 3927 N push and 3681 N pull.
The rear adjusting screw acts as a mechanical stop that shortens the effective stroke. For this 170 mm nominal stroke model, you can trim the travel back by up to 50 mm, creating a 120-170 mm usable window. It decelerates the load but does not lock it without live air.
