About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-50S
The AirTAC SAIJ100X95-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927 N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and a PT tapered port thread. The built-in magnet enables position sensing with CMSE reed or DMSE electronic switches.
With a 95 mm nominal stroke and a 50 mm adjustment code, this model provides a usable travel window of 45 to 95 mm. This wide tuning range allows precise end-position calibration during commissioning without swapping cylinders or adding external stops. The adjuster acts purely as a travel stop for deceleration, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-50S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 45 and 95 mm during machine setup to accommodate varying material thicknesses without mechanical rebuilds.
Product Size Changeover
Quickly adjust the stroke on packaging lines when switching between different product sizes, using the rear screw to set the new precise end position.
Heavy-Duty Forming
Leverage the 3927 N push force at 0.5 MPa for pressing or forming operations, using the SUS304 rod in environments where corrosion resistance is needed.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-50S the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust, such as the 3927 N push or 3681 N pull force at 0.5 MPa. If your application requires less force, stepping down to an 80 mm bore yields 2513 N push force, while moving up to a 125 mm bore provides 6136 N. The 50 mm adjustment range is ideal for product-size changeovers on a line, giving you a 45-95 mm window to dial in. For load-holding without continuous air pressure, you would need an external rod lock or a related type like the SAIL or BSAI, as the SAIJ adjuster is strictly a stop.
To replace an ISO 15552 cylinder, match the 100 mm bore, 95 mm stroke, G1/2 port, and your required mounting style from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. The 25 mm rod and M20x1.5 thread handle high side loads well, but even at 95 mm, always ensure proper external guiding for heavy loads.

- ✓ 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 SAIJ100BX95-50S FAQ
The rear adjuster screw lets you trim the effective stroke anywhere within a 45 to 95 mm window. It acts as a mechanical stop to set the end position, but it is not a lock; the cylinder still requires live air to hold a load.
At 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
