About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-40
The AirTAC SAIJ63X190-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 190 mm stroke and a 40 mm adjustment range, you can fine-tune the usable travel window down to 150 mm during commissioning without adding external stops. It delivers 1559 N of push force at 0.5 MPa, making it suited for medium-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance over standard carbon steel. The barrel is an extruded aluminum profile with sensor grooves on both sides, and the fluid porting utilizes PT tapered threads. The rear adjuster acts strictly as a mechanical stop to set the end position; it does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-40 Is Used
Machine Changeover
Dial in the 150-190 mm travel window during product size transitions without physically swapping out the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end-stop at commissioning to absorb mechanical tolerances and achieve precise final positioning of the 1559 N thrust output.
Assembly Line Indexing
Use the rear adjuster to set exact stroke limits for varying part sizes on a single pneumatic assembly station, maximizing setup flexibility.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-40 the Right Cylinder?
Choose this 63 mm bore when you need more thrust than the 50 mm class (982 N at 0.5 MPa) but want a smaller footprint than the 80 mm bore (2513 N at 0.5 MPa). An adjustable stroke is preferred over a fixed SAI cylinder when your machine setup requires variable end-stops or product-size changeovers, letting you dial in the 150-190 mm travel window precisely. To match this ISO 15552 footprint, specify a 63 mm bore, 190 mm stroke, 40 mm adjustment, PT G3/8 ports, and your required mounting bracket from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the total stroke is under 300 mm, side-load risks are moderate, but the 20 mm rod thread still requires external guiding for heavy lateral loads. For load-holding without live pressure, select the SAIL or BSAI series instead, as this adjuster is not a lock.
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 SAIJ63AX190-40 FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 318 kgf.
The rear adjuster screw allows you to shorten the effective stroke from its 190 mm nominal length by up to 40 mm, creating a usable travel window of 150 to 190 mm. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
