About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-30S
The AirTAC SAIJ80X100-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 100 mm travel back by up to 30 mm. This yields a usable end-position window of 70-100 mm, allowing precise fine-tuning at commissioning without bolting on external stops. It delivers a robust 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa) to handle heavy loads.
This SKU ships with a SUS304 stainless steel rod for superior corrosion resistance and includes a piston magnet for position sensing. It is fully dimensionally interchangeable per ISO 15552 mounting interfaces. Note that the rear adjuster acts purely as a travel stop to decelerate the end-of-stroke; it does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-30S Is Used
Machine Changeover
Dial in the 70-100 mm stroke during product size transitions on a packaging line, using the rear adjuster to set exact end-stops without swapping cylinders.
Clamping Force Control
Leverage the 2513 N push force at 0.5 MPa to securely hold workpieces, fine-tuning the clamping depth precisely to the material thickness via the adjuster.
Sensor-Verified Positioning
Utilize the integrated magnet with DMSE electronic sensors to confirm the adjusted retracted position, ensuring the 80 mm bore reached its tuned stop.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-30S the Right Cylinder?
Select this 80 mm bore when an application requires higher thrust than a 63 mm bore (which provides 1559 N at 0.5 MPa), but without stepping up to the massive 100 mm class. The adjustable 70-100 mm travel window is ideal for machine setups requiring variable end-stops during product changeovers. For load-holding without continuous air pressure, this plain SAIJ cylinder is insufficient; consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
This configuration features PT tapered ports sized G3/8, a 25 mm SUS304 rod, and a built-in magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors. It supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The 100 mm stroke is well within standard limits, keeping side-load risks low without needing an external guide.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80BX100-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. If pressure is increased to 0.9 MPa, the push force reaches 4523 N.
The rear adjuster acts as an external stopper that shortens the 100 mm nominal stroke by up to 30 mm, creating a usable travel window of 70-100 mm. It allows fine-tuning of the end position at commissioning, but it does not lock or hold the load without live air pressure.
