About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-100
The AirTAC SAIJ63X195-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous usable travel window of 95 to 195 mm, allowing you to dial back the nominal 195 mm stroke by up to 100 mm during commissioning. Delivering 1559 N of pull force at 0.5 MPa, it handles robust actuation tasks while maintaining the standard ISO 15552 mounting interface.
This SKU is configured with a SUS420J2 stainless steel piston rod (option A) for improved corrosion resistance compared to standard carbon steel. The barrel is an extruded aluminum profile with sensor grooves on both sides, ready to accept AirTAC CMSE reed or DMSE solid-state switches if a magnet is added later. It uses PT tapered port threads and operates at speeds between 30 and 800 mm/s.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-100 Is Used
Machine Changeover
Dial in the 95-195 mm travel window during product size changes to set new retract positions without physically swapping the actuator.
End-Position Tuning
Fine-tune the final retract distance during commissioning to absorb mechanical tolerances and achieve precise placement.
Variable Diverter Stops
Adjust the stroke on the fly to handle different package sizes on a sorting line, using the rear stopper to set the exact deflection distance.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-100 the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or frequent product changeovers, as the rear screw allows fine end-position tuning without swapping the cylinder or adding external mechanical stops. If you need less force, stepping down to a 50 mm bore yields 825 N of pull force at 0.5 MPa; stepping up to an 80 mm bore provides 2268 N.
Remember that the rear adjuster on this SAIJ cylinder acts only as a travel stop and does not hold the load without live air. For true fail-safe load holding, consider an AirTAC SAIL air-released lock or BSAI clamp-lock cylinder. To replace an existing ISO 15552 unit, match the 63 mm bore, 195 mm stroke, 100 mm adjustment, PT G3/8 port, and mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ63AX195-100 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 2182 N of push force. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 195 mm down to as little as 95 mm. It sets the travel end but does not lock the load without continuous air pressure.
