About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-100S
The AirTAC SAIJ80X1000-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 1000 mm stroke that can be fine-tuned backward by up to 100 mm, yielding a 900-1000 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it is built for demanding positioning tasks. This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE or DMSE sensors.
The rear adjuster acts purely as a mechanical stop to set the end position and must not be confused with a locking device. The cylinder relies on live air pressure to maintain force, so for dead-load holding without supply pressure, you must employ an external SAIL pneumatic lock or a pilot-operated check valve. Furthermore, the 1000 mm stroke on an 80 mm bore requires an external guide to prevent excessive rod side-loading and premature seal wear.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-100S Is Used
Long-Stroke Positioning
Dial in the exact 900-1000 mm travel window during machine setup to accommodate varying material lengths without adding external stopper blocks.
Stainless Rod Actuation
Leverage the SUS304 rod and 4523 N push force at 0.9 MPa in high-moisture manufacturing environments where carbon steel would corrode.
Sensor-Ready Changeover
Utilize the integrated magnet with DMSE solid-state sensors to confirm retracted positions across a 100 mm adjustment range during automated format changes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-100S the Right Cylinder?
Choose this 80 mm bore when an application requires approximately 2513 N of push force at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The adjustable stroke is ideal for machine commissioning and product changeovers, allowing you to dial in the exact end-stop from 900 to 1000 mm without swapping hardware. Because the stroke exceeds 300 mm, the 25 mm rod diameter and M20x1.5 thread still need external guidance to handle deflection. To match this ISO 15552 replacement exactly, specify an 80 mm bore, 1000 mm stroke, 100 mm adjustment, PT tapered port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and a -S magnet.

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 SAIJ80 Adjustable Cylinder SAIJ80BX1000-100S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, creating a 900-1000 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At a 0.5 MPa operating pressure, the SAIJ80X1000-100-S provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 4523 N of push force.
