About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75
The AirTAC SAIJ63X190-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 115 to 190 mm. It delivers a robust 2182 Newtons of push force at 0.7 MPa, making it highly suitable for mid-range automation tasks requiring exact end-position tuning.
This variant is built with a SUS420J2 stainless steel rod and uses PT tapered port threading. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract distance during commissioning; it does not lock the load without live air pressure. For position holding, you would need a SAIL or BSAI variant.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75 Is Used
Machine Changeover
Dial in the 115-190 mm travel window rapidly during product size changeovers without replacing the cylinder.
End-Stop Tuning
Use the 75 mm rear adjustment screw to fine-tune the retract position precisely during machine commissioning.
Assembly Positioning
Leverage the 2182 N push force to move parts into place while retaining flexibility over the final stroke distance.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75 the Right Cylinder?
Select this 63 mm bore model when your application requires a wide 75 mm adjustment band to dial in the exact end-stop on the fly, avoiding the need to swap cylinders or bolt on external stops. If your setup needs less force, stepping down to a 50 mm bore yields 1374 N of push force at 0.5 MPa; if you need more power, an 80 mm bore provides 3518 N at 0.7 MPa.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 190 mm stroke, PT port, and the 75 mm adjustment code. Note that SAIJ supports a specific mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets. Because the stroke is under 300 mm, side-load stress is minimal, but an external guide is still recommended for heavy 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-75 FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 190 mm down to 115 mm, providing a 75 mm tuning window. It functions as a mechanical stop and does not hold the load without live air pressure.
At a standard 0.7 MPa operating pressure, this 63 mm bore cylinder generates 2182 N of push force and 1402 N of pull force. It can deliver up to 2805 N of push force at its maximum 1.0 MPa rating.
