About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-100S
The AirTAC SAIJ200X190-100-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to fine-tune the stroke. This specific SKU provides a usable travel window of 90 to 190 mm, letting you shorten the nominal 190 mm stroke by up to 100 mm during machine commissioning. It delivers massive thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to 3204 kgf at 1.0 MPa.
Built with a SUS420J2 stainless steel rod (option A) for enhanced durability against side-load wear, it operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S model, it is factory-fitted with a magnet ready for CMSE reed and DMSE electronic solid-state switches. The PT tapered port is G3/4.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-100S Is Used
Heavy Press Tuning
Dial in the exact 90-190 mm end-position for large assembly presses, absorbing shock with the 50 mm cushion stroke.
Product Size Changeover
Quickly adapt a heavy-duty conveyor diverter by adjusting the stroke up to 100 mm during product line changeovers.
Commissioning Calibration
Fine-tune the retract end-stop during initial machine setup without bolting on external physical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-100S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires the highest force class in the SAIJ range, needing up to 15708 N push force at standard 0.5 MPa. If you need less force, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa. You would select this adjustable-stroke version over a fixed SAI when you need a variable end-stop to accommodate product-size changes on a line without physically swapping cylinders or adding external stops. The rear adjuster acts purely as a travel stop and works with the air cushions to decelerate the load; it does not hold the load without live air. For true load-holding without pneumatic pressure, consider the SAIL air-released lock or BSAI clamp-lock series. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting interface dimensions and uses the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX190-100S FAQ
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force scales up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel from the nominal 190 mm down to as little as 90 mm, creating a 100 mm adjustable window for precise end-position tuning.
