About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-10S
The AirTAC SAIJ100X180-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a precise 170-180 mm usable window, letting you fine-tune the retract end-position at commissioning without swapping out the cylinder or adding external stops. It delivers substantial thrust, offering 3927 N of push force and 3681 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. It uses a G1/2 port and omits the FB, CA, CB, and CR mounting hardware, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-10S Is Used
Machine Setup & Commissioning
Dial in the exact 170-180 mm retract position during initial machine commissioning without machining new mounting plates or swapping the cylinder.
Product-Size Changeovers
Quickly adapt a packaging or handling line to slightly different product lengths by turning the rear adjuster screw to shift the end-stop.
High-Force Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy fixtures while relying on the 10 mm adjustment window to perfect the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-10S the Right Cylinder?
Choose this 100 mm bore when you need higher force than a 80 mm bore (which provides 2513 N push at 0.5 MPa), but do not require the massive output of a 125 mm cylinder. The adjustable stroke is ideal for product-size changeovers on a line, allowing you to dial in the exact end-stop without installing external physical stops. Note that the rear adjuster acts solely as a travel stop to set deceleration, not as a lock; it will not hold a load without live air pressure. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder.
This SAIJ100X180-10-S configuration includes a PT tapered port thread, a SUS304 stainless steel rod, and a magnet for position sensing. It is dimensionally interchangeable per ISO 15552. Because the 180 mm stroke is under the 300 mm threshold, side-load stress is moderate, but the 25 mm rod diameter and M20x1.5 thread provide robust resistance to minor deflection. For longer unsupported strokes, always use an external guide.
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 SAIJ100BX180-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
A rear stopper screw lets you shorten the 180 mm nominal stroke by up to 10 mm, creating a 170-180 mm usable travel window. This allows fine-tuning of the end position at commissioning, but it acts as a stop and does not lock the load without live air pressure.
