About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-20
The AirTAC SAIJ200X190-20 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa. The -20 code provides a 20mm adjustment range, creating a 170-190mm usable travel window for dialing in the exact retract end position.
This heavy-duty actuator features a 40mm SUS420J2 stainless steel rod and a PT G3/4 port. The rear screw acts as a travel stop to fine-tune the end point during machine setup or product changeover, but it does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-20 Is Used
Heavy Press Tuning
Dial in the exact 170-190mm end position during heavy press commissioning without adding external mechanical stops.
Product Changeover
Quickly adjust the retract distance for varying product sizes on a high-force production line.
Automated Assembly
Handle massive payloads with a 3204 kgf maximum force capacity while fine-tuning the stroke end.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-20 the Right Cylinder?
Choose this 200mm bore when maximum thrust is required, stepping up from a 160mm bore that yields 10053N push at 0.5 MPa. The adjustable stroke is ideal for commissioning fine-tunes and variable end stops, avoiding the need to swap a fixed-stroke SAI cylinder. To replace this ISO 15552 unit, match the 200mm bore, 190mm stroke, 20mm adjustment, PT G3/4 port, and the specified mounting.
Because the 190mm stroke is substantial and the 40mm rod is heavy, an external guide is recommended to manage side loads. For load-holding without live pressure, use a SAIL or BSAI cylinder, as the SAIJ adjuster is a stop, 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 SAIJ200 Adjustable Cylinder SAIJ200AX190-20 FAQ
At 0.5 MPa, the push force is 15708N and the pull force is 15080N. At the maximum operating pressure of 1.0 MPa, it delivers a peak force of 3204 kgf.
The rear adjuster screw lets you shorten the 190mm nominal stroke by up to 20mm, providing a 170-190mm usable travel window. It sets the retract end position but does not lock or hold the load without live air.
