About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-50
The AirTAC SAIJ100X190-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 140-190 mm usable travel window from its 190 mm nominal length. It delivers 3927 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The rear adjustment screw acts as a travel stop to decelerate the piston, but it does not lock the load without live air pressure. For position holding, an external rod lock or SAIL cylinder is required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-50 Is Used
Machine Changeover
Dial in the exact end-stop from 140 to 190 mm during product size transitions without adding external stopper blocks.
Heavy Positioning
Leverage 3927 N of thrust to move heavy jigs into final position, using the rear screw for final micron-level tweaks.
Assembly Pressing
Set precise pressing depths on the line, adjusting the travel window on the fly to accommodate varying material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-50 the Right Cylinder?
Select this 100 mm bore when an application requires the 3927 N push force at 0.5 MPa but demands exact end-position tuning during commissioning without swapping hardware. If the load is lighter, stepping down to an 80 mm bore provides 2513 N, whereas heavier payloads require the 160 mm bore at 10053 N. The adjustable stroke is ideal for product changeovers where the end-stop varies by up to 50 mm.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 190 mm stroke, 50 mm adjustment, PT ports, and SUS304 rod material. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because the stroke is under 300 mm, side-load risks are minimal, but always guide heavy loads externally.
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 SAIJ100BX190-50 FAQ
The rear adjuster screw lets you shorten the effective travel from 190 mm down to 140 mm. This allows fine-tuning of the end position at commissioning or during product changeovers without replacing the cylinder.
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
