About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-100
The AirTAC SAIJ63X290-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 190-290 mm usable travel window, allowing you to dial back the nominal 290 mm stroke by up to 100 mm during commissioning. Delivering 1559 N of push force at 0.5 MPa, it fits mid-range automation tasks perfectly.
This variant uses a SUS420J2 stainless steel rod (code A) for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches. The rear adjuster acts purely as a travel stop to fine-tune the end position without needing external stops.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-100 Is Used
Product Changeovers
Quickly shift the 190-290 mm travel window to accommodate different part lengths on the same line without changing the cylinder.
Machine Setup
Fine-tune the retract end-position during commissioning to perfectly align tooling without adding bulky external stoppers.
Variable End Stops
Use the 100 mm adjustment range to dial in the exact stopping point for precision assembly operations requiring flexible travel.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-100 the Right Cylinder?
Select this 63 mm bore cylinder when you need variable end-position tuning on a 290 mm stroke, avoiding the need to swap cylinders during product changeovers. If your application requires less force, stepping down to a 50 mm bore yields 982 N at 0.5 MPa; for heavier loads, an 80 mm bore provides 2513 N. Because the stroke is 290 mm, ensure an external guide supports the load to prevent excessive side-loading on the M16x1.5 rod thread.
This model is dimensionally interchangeable per ISO 15552. It features a PT tapered port thread and accepts the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster is a stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ63AX290-100 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 318 kgf.
The rear adjuster screw lets you shorten the effective travel from the 290 mm nominal stroke down to 190 mm. This stopper only sets the end position and does not lock the load without live air pressure.
