Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-75S
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 190mm stroke, G3/8 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 SAIJ80 Adjustable Cylinder SAIJ80X190-75S
The AirTAC SAIJ80X190-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and features a 115-190mm usable travel window, letting you dial back the nominal 190mm stroke by up to 75mm during machine commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet enables position detection with CMSE reed or DMSE electronic switches.
This model uses a 25mm carbon steel rod with an M20x1.5 thread, providing robust resistance to side loads, while the PT tapered port ensures a tight pneumatic seal. The rear screw acts purely as a travel stop for end-position tuning and works alongside standard air cushions to decelerate the load. It does not function as a lock, so live air is required to hold position. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-75S Is Used
Product Changeovers
Quickly adapt the 115-190mm travel window on packaging lines when switching to different carton sizes, using the rear screw to set new end positions without mechanical rebuilds.
End-Position Calibration
Fine-tune the exact retraction point during machine commissioning to prevent tooling crashes, relying on the 75mm adjustment range to perfect the stroke.
Variable Stops
Handle multiple pressing depths on a single assembly station by adjusting the stroke stop per part number, leveraging the 2513N push force at 0.5 MPa.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-75S the Right Cylinder?
Select this 80mm bore when an application requires substantial force, such as the 2513N push or 2268N pull at 0.5 MPa. If your setup demands less thrust, stepping down to a 63mm bore yields 1559N push force. The wide 75mm adjustment range is ideal for product changeovers, allowing you to vary the end-stop without swapping cylinders or adding external stops. For fixed travel without the adjustment screw, a standard SAI cylinder is sufficient.
When replacing an ISO 15552 cylinder, match the 80mm bore, 190mm stroke, 75mm adjustment, G3/8 PT port, and -S magnet. Because the nominal stroke is 190mm, ensure adequate guiding for the extended rod to prevent excessive side-loading. If the machine requires true load-holding without continuous air pressure, integrate an external rod lock or specify an AirTAC SAIL or BSAI cylinder instead of relying on the adjuster.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80X190-75S FAQ
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this model, the 190mm nominal stroke can be trimmed back by up to 75mm, resulting in a usable travel window of 115-190mm. It works with the air cushions to decelerate the load but does not lock the position without live air.
At 0.5 MPa operating pressure, the SAIJ80X190-75-S provides 2513N of push force and 2268N of pull force. If higher force is needed, stepping up to a 100mm bore yields 3927N push force at the same pressure.
