About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-75S
The AirTAC SAIJ100X195-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 195 mm nominal stroke by up to 75 mm for a usable travel window of 120-195 mm. Delivering 3927 N of push force at 0.5 MPa (up to 7068 N at 0.9 MPa), it handles heavy actuation tasks with precision. The SUS304 stainless steel rod (code B) provides excellent corrosion resistance, and the -S magnet integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves.
This adjustable-stroke design allows fine end-position tuning at commissioning or product changeover without swapping the cylinder or adding external stops. The rear adjuster acts purely as a mechanical travel stop and deceleration point—it does not hold the load without live air pressure. It features a G1/2 port, M20x1.5 rod thread, and variable air cushions at both ends (36 mm cushion length) operating at 30-800 mm/s.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-75S Is Used
Product Changeover
Dial in the 120-195 mm stroke window instantly on packaging lines when switching carton sizes, bypassing the need to swap cylinders or bolt on external stops.
Heavy Pressing
Leverage 7068 N of push force at 0.9 MPa for heavy stamping or pressing operations requiring exact end-position tuning during machine setup.
Corrosive Environments
Rely on the SUS304 stainless steel rod and durable seals for reliable actuation in washdown or corrosive manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-75S the Right Cylinder?
Choose this 100 mm bore when 80 mm (2513 N push @ 0.5 MPa) is too weak or 125 mm (6136 N push @ 0.5 MPa) is oversized for your machine. The 75 mm adjustment range is ideal for packaging lines needing frequent product-size changeovers. For load-holding without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is not a brake.
To replace an ISO 15552 cylinder, match the 100 mm bore, 195 mm stroke, 75 mm adjustment, PT tapered ports, and -S magnet. The SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the stroke is under 300 mm, side-load risks are minimal, though the robust 25 mm rod and M20x1.5 thread handle standard stresses effectively.
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 SAIJ100BX195-75S FAQ
At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
A rear adjusting screw mechanically stops the piston up to 75 mm short of its 195 mm nominal stroke, creating a 120-195 mm usable travel window. It acts as a stop and does not lock the load without live air.
