About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-50
The AirTAC SAIJ63X1000-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, enabling you to fine-tune the effective travel window from 950 to 1000 mm during commissioning. It delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa, matching the standard SAI output class.
This variant uses a SUS420J2 stainless steel rod (option A) for better corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic solid-state switches if a magnet is added later. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-50 Is Used
Machine Changeover
Dial in the 950-1000 mm travel window during product size changes without physically swapping out the long-stroke cylinder or adding external mechanical stops.
End-Position Tuning
Perfect for long-stroke automated assembly lines where the exact retract position must be fine-tuned at commissioning to prevent impact damage.
Long-Stroke Diverter
Provides adjustable stroke for large conveyor sorting gates where the exact stopping point needs occasional adjustment to handle varying package dimensions.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-50 the Right Cylinder?
Choose this 63 mm bore when you need 1559 N push force at 0.5 MPa, which sits neatly between the 982 N of a 50 mm bore and the 2513 N of an 80 mm bore. The 50 mm adjustment range is highly valuable for machine changeovers, allowing you to dial in the exact end-stop without swapping the cylinder or adding external stops, unlike a fixed SAI model.
Because the 1000 mm stroke approaches the 1500 mm maximum standard limit for this bore, the 20 mm rod and M16x1.5 thread will need external guide support to prevent excessive side-loading and rod sag over that long unsupported distance. For applications requiring the load to be held without continuous air pressure, note that this cylinder's adjuster is not a lock; you should look at the SAIL or BSAI series instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ63AX1000-50 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50 mm, providing a usable travel window of 950 to 1000 mm. It acts as a mechanical stop to set the end position and relies on the built-in air cushion for deceleration; it does not lock or hold the load without continuous air pressure.
At 0.5 MPa it provides 1559 N of push force and 1402 N of pull force, with a maximum operating pressure of 1.0 MPa. The standard speed range for this bore size is 30-800 mm/s.
