About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-30
The AirTAC SAIJ100X195-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 165-195 mm, allowing you to dial back the nominal 195 mm stroke by up to 30 mm. This fine-tuning capability is ideal for precise end-position calibration during commissioning without swapping out the physical cylinder. Delivering a robust 3927 N push force at 0.5 MPa, it handles heavy loads with ease.
This variant is configured with a SUS304 stainless steel rod (material code B) for superior corrosion resistance and includes PT tapered port threads (G1/2). The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE or DMSE electronic sensors. Unlike a fixed-stroke SAI, this model lets you adjust the retract end-stop on the fly, though the adjuster functions strictly as a travel stop and does not lock the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-30 Is Used
Machine Setup & Changeover
Quickly fine-tune the 165-195 mm travel end-stop during product changeovers without fabricating new external spacers or replacing the cylinder.
Variable End-Stop Positioning
Dial in the exact retract position on heavy machinery requiring 3927 N of push force, adjusting the stroke by up to 30 mm as tooling wears.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or corrosive manufacturing areas while maintaining ISO 15552 dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-30 the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires 3927 N of push force or 5497 N at 0.7 MPa. If your setup demands less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable 165-195 mm travel window is perfect for product changeovers on a production line where exact end positions vary slightly between runs.
When matching this for an ISO 15552 replacement, verify the 100 mm bore, 195 mm stroke, 30 mm adjustment range, G1/2 port, and required mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Because the stroke is under 300 mm, side-load concerns are minimal, but an external guide is still recommended for heavy lateral loads. Remember that the rear adjuster only decelerates the travel end; for true load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.

- ✓ 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 SAIJ100BX195-30 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 195 mm down to 165 mm, creating a 165-195 mm usable window. This stopper lets you fine-tune the end position at commissioning, but it does not lock the load without continuous air pressure.
