About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-100S
The AirTAC SAIJ100X800-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 700-800 mm usable travel window from its 800 mm nominal stroke. Equipped with a SUS304 stainless steel rod and a -S magnet, it delivers 3927 N of push force at 0.5 MPa. The PT tapered port threads ensure a high-integrity pneumatic seal.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The integrated sensor grooves on both sides of the extruded aluminum barrel accept CMSE reed or DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-100S Is Used
Variable End-Stop Forming
Dial in the 700-800 mm retract position on the fly for metal forming or bending presses that process multiple material lengths.
Product Changeover Diverters
Adjust the stroke up to 100 mm during packaging line format changes to accommodate different carton sizes without retooling.
Long-Stroke Assembly Presses
Leverage the 3927 N push force and fine-tune the end position for large-component assembly stations requiring precise clamping depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-100S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) lacks the necessary thrust, but a 125 mm bore is physically oversized. The 100 mm adjustment window is ideal for product changeovers requiring variable end-stops. Because the stroke is 800 mm, an external guide is strongly recommended to support the load and prevent excessive side-loading on the rod.
To match this ISO 15552 interchangeable cylinder, specify: 100 mm bore, 800 mm stroke, 100 mm adjust, PT G1/2 port, SUS304 (B) rod, -S magnet, and a mounting set from Basic, FA, LB, TC, FTC, TCM1, or TCM2. The rear adjuster acts only as a travel stop, not a lock; for load-holding without live air, select an AirTAC SAIL or BSAI cylinder.
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 SAIJ100BX800-100S 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 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to trim the effective stroke by up to 100 mm, providing a usable travel window of 700-800 mm. It functions as a physical stop to set the end position and does not lock the load without live air pressure.
