About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-40
The AirTAC SAIJ200X190-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. It features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for a high-integrity pneumatic seal. By turning the external rear screw, you can fine-tune the effective travel down from the 190mm nominal stroke, creating a precise 150-190mm usable window without adding external stops.
This adjustable end-position capability is ideal for product-size changeovers on heavy machinery, letting you dial in the exact retract distance at commissioning. The rear mechanism acts purely as a mechanical travel stop to set the end position; it does not hold the load without live air pressure. For load-holding requirements without continuous air, an external rod lock or a related SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-40 Is Used
Heavy Machinery Changeover
Dial in the 150-190mm retract distance during heavy equipment setup to accommodate different product dimensions without swapping the actuator.
Press End-Position Tuning
Fine-tune the end-of-stroke stopping point on large pneumatic presses at commissioning, using the rear stopper to absorb minor dimensional variations.
Large Material Positioning
Adjust the stroke window on the fly for positioning heavy materials or workpieces, ensuring precise alignment without external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-40 the Right Cylinder?
Choose this 200mm bore when your application demands maximum push force, stepping up from a 160mm bore that yields 10053N at 0.5 MPa. The adjustable stroke is selected over a fixed-stroke SAI cylinder when you need variable end-stops for machine setup or product changeovers. Because this is a large-bore actuator, ensure your pneumatic supply can deliver the necessary volume to operate efficiently within the 30-500mm/s speed range. To match an ISO 15552 replacement, verify the 200mm bore, 190mm stroke, 40mm adjustment, PT port thread, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface.
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 SAIJ200 Adjustable Cylinder SAIJ200BX190-40 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 21991N at 0.7 MPa.
The rear adjuster screw allows you to shorten the 190mm nominal stroke by up to 40mm, providing an adjustable travel window between 150mm and 190mm. This stopper sets the end position but does not function as a lock to hold the load without air pressure.
