About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-100S
The AirTAC SAIJ32X850-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the usable travel window between 750 and 850 mm. Delivering a push force of 563 N at 0.7 MPa, it uses a 12 mm carbon steel core but is built here with an SUS420J2 stainless steel rod (A option) for superior corrosion resistance. It includes a magnet for position sensing and uses PT tapered ports.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster functions purely as a travel stop to set the end position, not as a lock to hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-100S Is Used
Machine Changeover
Dial in the exact end-stop during product size changeovers without physically replacing the cylinder or adding external mechanical stops.
Long-Stroke Positioning
Utilize the 850 mm travel for extended reach while retaining a 100 mm adjustment window to perfect the final landing position.
Corrosive Assembly Lines
Leverage the SUS420J2 stainless steel rod and adjustable end-stop for fine-tuned assembly operations in environments requiring rust resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-100S the Right Cylinder?
Choose this 32 mm bore cylinder when you need precise end-position tuning within a 750-850 mm travel window. If your application requires higher thrust, stepping up to the 40 mm bore yields 879 N of push force at 0.7 MPa. Because the 850 mm stroke is long and the 12 mm rod is relatively slender, an external guide is recommended to prevent excessive side-load deflection. For load-holding without continuous air pressure, this plain SAIJ is insufficient; consider an AirTAC SAIL or BSAI series instead. This SKU matches ISO 15552 mounting dimensions with a 32 mm bore, 850 mm stroke, 100 mm adjuster, PT ports, and a magnet for CMSE or DMSE sensors. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 Adjustable Cylinder SAIJ32 SAIJ32AX850-100S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 100 mm. For this 850 mm stroke model, the usable travel window is 750-850 mm, allowing you to fine-tune the retract end position at commissioning.
At 0.7 MPa operating pressure, the SAIJ32X850-100-S provides 563 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
