About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-10S
The AirTAC SAIJ100X85-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75-85 mm for precise end-position tuning. Delivering 3927 N of push force at 0.5 MPa, it handles demanding actuation tasks with ease. This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
The integrated rear stopper allows you to fine-tune the retract position during commissioning without adding external stops. Fluid ports are PT tapered, sized at G1/2 for this bore. Remember that the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-10S Is Used
Precision Machine Setup
Fine-tune the 75-85 mm travel window during commissioning to achieve exact positioning without machining custom spacers.
Product Changeover
Quickly adjust the retract stop to accommodate varying package sizes on an automated packaging line.
Heavy-Duty Clamping
Leverage 3927 N of push force at 0.5 MPa to secure heavy workpieces while dialing in the exact clamping depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-10S the Right Cylinder?
Choose this 100 mm bore cylinder when an 80 mm bore falls short, delivering 2513 N push force at 0.5 MPa compared to the 100 mm bore's 3927 N. The 10 mm adjustment range is ideal for dialing in exact end stops during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. For applications requiring load holding without continuous air pressure, consider the SAIL or BSAI series instead.
To match this ISO 15552 interchangeable cylinder, confirm the 100 mm bore, 85 mm stroke, 10 mm adjustment, PT G1/2 port, and the -S magnet option. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ100BX85-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the nominal 85 mm stroke by up to 10 mm, creating a 75-85 mm usable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
