Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-30
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 170mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-30
The AirTAC SAIJ100X170-30 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 30 mm. This creates a 140-170 mm usable travel window, enabling fine end-position tuning at commissioning without swapping the cylinder or adding external stops. In the 100 mm bore class, it delivers 7068 N of push force at 0.9 MPa and 3927 N at 0.5 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and carries a robust M20x1.5 rod thread paired with a 25 mm rod diameter to handle high side loads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic sensors, though this specific SKU is supplied without a magnet. The rear adjuster acts purely as a travel stop for deceleration and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-30 Is Used
Product Changeover
Dial in the 140-170 mm travel window during format changes on a packaging line without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract position precisely at machine commissioning to perfect a pressing operation.
Adjustable Ejection
Vary the ejection stroke on an assembly line to handle different part sizes on the same fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-30 the Right Cylinder?
Choose this 100 mm bore adjustable cylinder when a machine requires variable end-stops or product-size changeovers, stepping up from a 63 mm bore that provides only 2182 N of push force at 0.7 MPa. The SAIJ design omits the FB, CA, CB and CR mounts, offering a focused mounting set of Basic, FA, LB, TC, FTC, TCM1 and TCM2. For load-holding without continuous air pressure, select the SAIL or BSAI series instead, as the rear adjuster here is not a lock.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 170 mm stroke, 30 mm adjustment range, PT tapered G1/2 port, and the specified mounting interface. Because the 170 mm stroke is relatively short, side-load stress is minimal, but an external guide is still recommended for heavy lateral loads.
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 SAIJ100BX170-30 FAQ
The rear adjuster screw lets you shorten the 170 mm nominal stroke by up to 30 mm, providing a usable travel window of 140-170 mm. It acts as a mechanical stop to set the end position and does not lock the load without live air.
It provides 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa. The maximum thrust is 801 kgf at 1.0 MPa.
