About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-20S
The AirTAC SAIJ100X190-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 190mm nominal stroke by up to 20mm for a precise 170-190mm usable travel window. It delivers a robust 3927N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. This configuration features a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic sensors.
Unlike a fixed-stroke SAI cylinder, this adjustable model lets you fine-tune the retract end-position during commissioning or product changeovers without adding bulky external stops. The rear adjuster acts purely as a travel stop to set the deceleration point alongside the standard air cushions; it does not lock the load. For position-holding without live air pressure, a SAIL or BSAI locking cylinder is required. Mounting options include the standard SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-20S Is Used
Precision End-Stop Tuning
Dial in the exact 170-190mm travel window during machine commissioning to perfect part seating without swapping out the entire actuator.
Product Size Changeover
Quickly adapt the retract position on a packaging line when running different carton sizes by adjusting the rear stopper screw.
Heavy-Duty Positioning
Leverage the 3927N push force to move heavy pallets or fixtures into place, relying on the stopper to set the final resting point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-20S the Right Cylinder?
Select this 100mm bore cylinder when an application demands high force (3927N at 0.5 MPa) alongside variable end-stop positioning. If your process requires less thrust, stepping down to an 80mm bore yields 2513N of push force, while stepping up to a 125mm bore provides 6136N. The 20mm adjustment range is ideal for machine setups requiring precise end-position tuning without machining new hard stops.
Because this is a 190mm stroke unit, the 25mm rod diameter and M20x1.5 rod thread provide excellent rigidity, though any long, unsupported load still requires an external guide to prevent side-loading damage. To match this ISO 15552 interchangeable cylinder, specify the 100mm bore, 190mm stroke, 20mm adjustment, PT tapered ports, SUS304 (B) rod material, and the -S magnet option. Operating speed ranges from 30-800 mm/s.

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 SAIJ100BX190-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 190mm nominal stroke by up to 20mm, providing a usable travel window of 170-190mm. It sets the end position and works with the air cushions for deceleration, but it does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the 100mm bore generates 3927N of push force and 3681N of pull force. The -S magnet option allows position detection using AirTAC CMSE reed switches or DMSE solid-state electronic sensors mounted in the dual-side sensor grooves.
