About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75S
The AirTAC SAIJ63X190-75-S is a double-acting ISO 15552 profile cylinder featuring a SUS420J2 stainless steel rod and a built-in rear stroke adjuster. It provides a nominal 190 mm stroke that can be fine-tuned down by up to 75 mm, creating a precise 115-190 mm usable travel window for highly adaptable machinery setup.
Delivering 1559 N of pull force at 0.5 MPa, this bore 63 unit is equipped with a PT tapered G3/8 port and a magnet for CMSE or DMSE sensors. The rear screw acts purely as an end-position stop for changeovers and relies on the variable air cushion for deceleration; it does not lock the load without continuous live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75S Is Used
Product Changeovers
Dial in the 115-190 mm travel window during format changes on a packaging line, using the rear stopper to instantly match new carton or product sizes without changing cylinders.
Machine Setup
Fine-tune the exact end-of-stroke position during commissioning to perfect a pressing or forming operation, absorbing mechanical tolerances directly at the rear adjuster.
Variable Diverting
Adjust the reach of a diverter arm on a conveyor system to handle different package widths, relying on the 63 mm bore to deliver consistent 1559 N pull force.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75S the Right Cylinder?
Select this 63 mm bore cylinder when an application requires 1559 N pull force at 0.5 MPa but demands significant flexibility in the end-stop position. The generous 75 mm adjustment window is perfect for production lines running multiple product sizes, allowing you to reposition the stopper during changeover rather than physically swapping out a fixed-stroke SAI cylinder. If your process requires less force, stepping down to a 50 mm bore yields 825 N pull, while moving up to an 80 mm bore provides 2268 N.
Because this model features a 190 mm stroke, the 20 mm rod diameter handles standard side loads adequately, though any significantly extended or heavy unsupported load still requires an external guide. For holding a load securely without live air, this adjustable stopper is insufficient; you must integrate an external rod lock or specify a SAIL or BSAI cylinder. This configuration includes a magnet for position sensing and uses PT port threads.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 1559 N of push force. At the maximum 1.0 MPa pressure, it can deliver up to 318 kgf.
The rear adjuster screw allows you to shorten the effective stroke from its 190 mm nominal length by up to 75 mm, providing a usable travel range of 115 to 190 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
