About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-20
The AirTAC SAIJ200X105-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 105 mm nominal stroke by up to 20 mm. This creates an 85-105 mm usable travel window, enabling precise end-position tuning at commissioning without adding external stops. It delivers massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa.
This heavy-duty actuator features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-20 Is Used
Heavy Press Tuning
Fine-tune the 85-105 mm travel window during heavy press commissioning to dial in the exact contact force without swapping actuators.
Product Changeover
Quickly adjust the rear stopper on a packaging line to accommodate varying product sizes within the 20 mm adjustment range.
Robotic End Effectors
Use the massive 15708 N push force to actuate large grippers, relying on the SUS304 rod for corrosion resistance in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-20 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, as it generates up to 3204 kgf at 1.0 MPa. If you need less thrust, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers, whereas a fixed SAI cylinder is better for set-and-forget operations. Because this model lacks a lock, use a SAIL or BSAI cylinder if you need fail-safe load holding.
For an ISO 15552 replacement, match the 200 mm bore, 105 mm stroke, 20 mm adjustment, PT G3/4 port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the stroke is over 300 mm on larger variants, always ensure external guiding to prevent side-load damage, though this 105 mm stroke is well within safe rod buckling limits.
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 SAIJ200BX105-20 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the 105 mm nominal stroke by up to 20 mm, creating an 85-105 mm usable travel window. This mechanical stopper only sets the end position and does not lock or hold the load without continuous air pressure.
