About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-40S
The AirTAC SAIJ100X190-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 150-190 mm usable travel window. Delivering 3927 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet for position sensing.
The rear adjusting screw acts as a travel stop to fine-tune end positions at commissioning without adding external stops. It features PT tapered ports (G1/2) and a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omitting FB and CA options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-40S Is Used
Machine Changeover
Dial in the exact 150 to 190 mm end-stop during product size transitions without swapping the physical cylinder.
Position Tuning
Fine-tune the retract end position at commissioning to perfect pressing or clamping alignment.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or mildly corrosive environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-40S the Right Cylinder?
Choose this 100 mm bore when you need higher thrust than the 80 mm version (2513 N push at 0.5 MPa) but want to avoid the mass of a 125 mm unit. The 40 mm adjustment window is ideal for product changeovers, allowing you to dial back the 190 mm nominal stroke to 150 mm on the fly.
For exact ISO 15552 replacement, match the 100 mm bore, 190 mm stroke, 40 mm adjustment, G1/2 PT ports, SUS304 rod, and -S magnet. Since the stroke is under 300 mm, side-load risks are minimal, but an external guide is still recommended for heavy lateral loads. Note that the rear adjuster is a stop, not a lock; for load-holding without live air, use an AirTAC SAIL or BSAI cylinder.
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 SAIJ100BX190-40S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective travel anywhere within a 150 to 190 mm window. It only sets the end position and does not lock the load without live air pressure.
