About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-40S
The AirTAC SAIJ100X170-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 170 mm nominal stroke by up to 40 mm for a usable travel window of 130-170 mm. It delivers robust thrust, pushing 3927 N at 0.5 MPa and reaching 7068 N at 0.9 MPa, making it well-suited for heavy actuation tasks. This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
The rear adjustment screw acts as a travel stop to fine-tune end positions at commissioning without adding external stops. It is not a locking device; the cylinder relies on live air pressure to hold loads. For applications requiring position holding without constant air, SAIL or BSAI variants are recommended. The extruded aluminum barrel provides standard ISO 15552 mounting interchangeability.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-40S Is Used
Machine Changeover
Dial in the 130-170 mm travel window during product size changes without physically replacing the cylinder or adding external mechanical stops.
Heavy Clamping
Leverage up to 7068 N of pushing force at 0.9 MPa to secure heavy workpieces, using the rear adjuster to fine-tune the exact clamp position.
Automated Pressing
Achieve precise pressing depths in assembly lines by trimming the stroke up to 40 mm, ensuring consistent results across varying component tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-40S the Right Cylinder?
Select this 100 mm bore cylinder when your application requires high force (3927 N push at 0.5 MPa) and precise end-position tuning within a 130-170 mm window. If your force requirements are lower, a 80 mm bore provides 2513 N push at 0.5 MPa, whereas stepping up to a 125 mm bore yields 6136 N. The adjustable stroke is ideal for product changeovers, allowing you to trim travel without swapping the cylinder.
This SAIJ100X170-40-S configuration includes a PT tapered port thread, a SUS420J2 stainless steel rod, and a magnet (-S) for position sensing. It supports the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the 170 mm stroke is under the 300 mm threshold, side-load stress is moderate, but long unsupported loads should still use an external guide.

- ✓ 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 SAIJ100AX170-40S FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 40 mm, providing a usable travel window of 130-170 mm. This allows for fine-tuning the end position during setup without changing the cylinder.
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
