About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-40
The AirTAC SAIJ100X170-40 is a double-acting ISO 15552 profile cylinder engineered with a rear stroke adjuster, allowing you to dial back the 170 mm nominal stroke by up to 40 mm. This creates a precise 130-170 mm usable travel window, enabling fine end-position tuning at commissioning without swapping out the barrel or adding external stops. It delivers a robust 3927 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
Built with a SUS420J2 stainless steel rod for enhanced durability against side-load wear, this model features a G1/2 PT tapered port and dual-sided sensor grooves. The rear adjustment mechanism acts purely as a travel stop to set the deceleration point alongside the variable air cushions; it is not a locking device and will not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-40 Is Used
Product Changeover
Quickly adapt to varying package sizes on a packaging line by dialing the retract stroke from 170 mm down to 130 mm via the rear adjuster.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to achieve exact clamping distances without adding external mechanical spacers.
Heavy Forming
Leverage the 3927 N push force at 0.5 MPa for pressing operations, using the adjustable stop to set precise material deformation depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-40 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust—stepping up from a 63 mm bore gives you 1559 N at 0.5 MPa, while this 100 mm model provides 3927 N at the same pressure, offering a significant leap in pushing power. The adjustable 130-170 mm travel window is ideal for product-size changeovers on a line, allowing operators to fine-tune the retract end without machining new hard stops. For load-holding requirements without continuous air pressure, a standard SAIJ is insufficient; you should instead consider an AirTAC SAIL or BSAI series cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 170 mm stroke, 40 mm adjustment range, G1/2 PT port, and SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR variants. Because the 170 mm stroke is relatively short for this large bore, side-load risks are manageable, but an external guide is still recommended for heavy offset loads.

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 SAIJ100AX170-40 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At the maximum 1.0 MPa pressure, the push force reaches 801 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm from the 170 mm nominal length, providing a usable travel window of 130 to 170 mm. This stopper sets the travel end and works with the air cushion, but it does not lock the load without live air pressure.
