About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-50
The AirTAC SAIJ63X160-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 110 to 160 mm. Delivering 2182 N of push force at 0.7 MPa, it handles robust actuation while allowing exact end-position tuning without adding external stops. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
This model features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It uses a PT tapered port thread and relies on the standard SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. The rear adjuster functions strictly as a travel stop to dial in the stroke, not as a load-holding lock.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-50 Is Used
Machine Changeover
Dial in the 110-160 mm travel window during product size transitions on a packaging line without physically swapping the actuator.
End-Position Tuning
Fine-tune the retract stroke by up to 50 mm at commissioning to perfect the seating pressure of a clamping assembly.
Adjustable Ejection
Vary the ejection distance on an assembly conveyor to accommodate different part depths without adding external mechanical stops.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-50 the Right Cylinder?
Choose this 63 mm bore cylinder when your application requires 2182 N of push force at 0.7 MPa and on-the-fly stroke adjustments between 110 and 160 mm. If your force requirements are lower, stepping down to a 50 mm bore yields 1374 N of push force, while upgrading to an 80 mm bore provides 3518 N for heavier loads.
The adjustable rear stopper is ideal for machine setup and product changeovers, allowing you to trim the stroke by up to 50 mm without swapping the cylinder. Because the adjuster and air cushions only decelerate the travel end, this cylinder cannot hold a load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. To replace an existing ISO 15552 unit, match the 63 mm bore, 160 mm stroke, PT G3/8 port, and appropriate mounting bracket.
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 SAIJ63AX160-50 FAQ
At an operating pressure of 0.7 MPa, this 63 mm bore double-acting cylinder generates 2182 N of push force and 1402 N of pull force.
The rear adjuster acts as a mechanical stop that lets you trim the nominal 160 mm stroke back by up to 50 mm, providing an effective travel window of 110 to 160 mm for fine-tuning at commissioning.
