About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-20
The AirTAC SAIJ100X190-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 190 mm travel by up to 20 mm for a precise 170-190 mm usable window. It delivers robust thrust, pushing 5497 N and pulling 3681 N at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This SKU features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a G1/2 PT tapered port. The extruded aluminum barrel incorporates sensor grooves on both sides, and the adjustable stopper lets you fine-tune the retract end position during commissioning without adding external stops or swapping the cylinder.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-20 Is Used
Machine Changeover
Dial in the 170-190 mm retract position during product size changes without swapping hardware.
Heavy Fixture Clamping
Leverage 5497 N of push force at 0.7 MPa to secure heavy workpieces while tuning the exact clamp distance.
End-Position Calibration
Fine-tune the final retract stop during commissioning to perfect multi-stage assembly alignments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-20 the Right Cylinder?
Select this 100 mm bore cylinder when an 80 mm bore is insufficient (the 80 mm variant yields 3518 N push at 0.7 MPa) or when you want to avoid stepping up to a 125 mm body. The built-in 20 mm adjustment mechanism is ideal for product changeovers on a line, letting you set variable end stops on the fly. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series. Since the 190 mm stroke is under 300 mm, side-load concerns are minimal, but always guide long unsupported loads.
To match this ISO 15552 interchangeable cylinder, specify a 100 mm bore, 190 mm stroke, 20 mm adjustment range, G1/2 PT ports, and your desired mounting from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (FB, CA, CB, and CR are omitted from this series).
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 SAIJ100 Adjustable Cylinder SAIJ100BX190-20 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. At 0.5 MPa, it outputs 3927 N push and 3681 N pull.
The rear adjuster acts as a mechanical stop that lets you shorten the 190 mm nominal stroke by up to 20 mm, creating a 170-190 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
