About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX15-10S
The AirTAC SAIJ100X15-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position without swapping out hardware. With a 15 mm nominal stroke and a 10 mm adjustment range, it provides a highly precise 5-15 mm usable travel window. This bore size delivers 5497 N of push force at 0.7 MPa, making it robust enough for heavy pressing or holding tasks.
This specific SKU is equipped with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The adjuster acts purely as a travel stop to decelerate the load at the end of stroke; it does not hold the load without live air pressure. For applications requiring true load holding, consider the SAIL or BSAI locking cylinder series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX15-10S Is Used
Short-Stroke Pressing
Delivers 5497 N of force at 0.7 MPa for compact pressing operations, with the 5-15 mm travel window allowing exact depth tuning for different material thicknesses.
Machine Changeover
The rear stopper screw lets operators dial in the exact end position during product line changeovers without machining new external stops or replacing the cylinder.
Sensor-Ready Ejection
The integrated magnet works with DMSE solid-state sensors to confirm part ejection at high speeds up to 800 mm/s, while the SUS304 rod withstands washdown environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX15-10S the Right Cylinder?
Choose this adjustable-stroke cylinder when your machine setup requires precise end-position tuning during commissioning or product changeover, rather than relying on a fixed-stroke SAI cylinder. If you need slightly less force, stepping down to an 80 mm bore yields 3518 N of push force at 0.7 MPa. Because the 15 mm stroke is well under the 300 mm threshold, side-load concerns from unsupported rod length are minimal, though the robust 25 mm rod and M20x1.5 thread handle high axial stress easily.
To match this exact configuration, specify the 100 mm bore, 15 mm stroke, 10 mm adjustment, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ100BX15-10S FAQ
At a 0.7 MPa operating pressure, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. It can deliver a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster screw lets you trim the effective travel by up to 10 mm. This creates a 5 to 15 mm usable travel window from the 15 mm nominal stroke, allowing precise end-position tuning at commissioning without adding external stops.
