About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX1000-100S
The AirTAC SAIJ50X1000-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 900 to 1000 mm window. It delivers 982 N of push thrust at 0.5 MPa and utilizes a G1/4 port. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. Because the nominal stroke is 1000 mm, you must use an external guide to prevent excessive side-loading on the rod, as the rear adjuster and air cushions only decelerate the end of travel and do not lock the load.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX1000-100S Is Used
Variable End-Stop Positioning
Dial in the exact end position within the 900-1000 mm range during machine setup to accommodate varying product dimensions without changing hardware.
Product Changeover Systems
Quickly adjust the retract stop by up to 100 mm on packaging or sorting lines to handle different package sizes on the fly.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable long-stroke actuation in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX1000-100S the Right Cylinder?
Choose this 50 mm bore cylinder when your application requires up to 982 N of push force at 0.5 MPa, stepping up from a 40 mm bore that provides 628 N, or down from a 63 mm bore delivering 1559 N. The 100 mm adjustment range is ideal for machine changeovers where the exact end position needs dialing in without physically swapping cylinders or adding external stops.
For load-holding without continuous air pressure, note that this SAIJ adjuster acts strictly as a mechanical stop, not a brake; you would need to select an AirTAC SAIL or BSAI cylinder instead. This model is dimensionally interchangeable per ISO 15552 with matching 50 mm bore, 1000 mm stroke, PT G1/4 ports, Basic/LB/TC mounting options, and the -S magnet.

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50BX1000-100S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 100 mm, providing a usable travel window of 900 to 1000 mm. It allows fine-tuning the end position at commissioning without replacing the cylinder.
At a standard operating pressure of 0.5 MPa, the SAIJ50X1000-100-S provides 982 N of push thrust and 825 N of pull thrust. At 0.7 MPa, the push force increases to 1374 N.
