About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-75S
The AirTAC SAIJ100X95-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and a PT tapered port. The built-in magnet supports position sensing. By turning the rear screw, you achieve a usable travel window of 20-95 mm without swapping the cylinder.
This adjustable-stroke design eliminates the need for external stops during machine setup or product changeover. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts only as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-75S Is Used
Product Changeover
Dial the stroke from 95mm down to 20mm instantly on the production line when switching to a different package size, avoiding mechanical rebuilds.
Variable End-Stop Setup
Use the 75mm adjustment window to fine-tune the retract end-position during commissioning until the exact kinematic timing is achieved.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for pushing loads in washdown or mildly corrosive environments while maintaining precise end-stop control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-75S the Right Cylinder?
Choose this 100mm bore when the 80mm class is insufficient; an 80mm bore provides 2513N push at 0.5 MPa, while this SAIJ100X95-75-S yields 3927N at the same pressure. The 75mm adjustment range is exceptionally wide, allowing a 95mm nominal stroke to be dialed all the way back to 20mm for highly variable product sizes. For position holding without live air, select a SAIL or BSAI cylinder instead, as this rear adjuster is strictly a stop.
When replacing an ISO 15552 cylinder, match the 100mm bore, 95mm stroke, G1/2 port, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. The -S magnet pairs with AirTAC CMSE reed and DMSE electronic sensors. Since the stroke is under 300mm, side-load risks are lower, but external guides are still recommended for heavy loads.
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 SAIJ100BX95-75S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At the maximum 1.0 MPa pressure, it achieves 801 kgf.
The rear adjuster screw lets you trim the effective travel from the 95mm nominal stroke down to as little as 20mm. This creates a 20-95mm usable window, allowing precise end-position tuning without adding external stops.
