About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-50S
The AirTAC SAIJ80X100-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 50-100 mm, allowing you to dial back the standard 100 mm stroke by up to 50 mm during machine commissioning without adding external stops. Delivering a robust 4523N push force at 0.9MPa, it handles heavy positioning tasks with ease.
This unit includes a SUS304 stainless steel rod for corrosion resistance and an integrated magnet for CMSE and DMSE sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster acts purely as a travel stop rather than a load lock.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-50S Is Used
Variable End-Stop Positioning
Perfect for test fixtures where the exact end-of-stroke contact point must be fine-tuned within a 50-100mm window across different test parameters.
Product Size Changeover
Quickly adapt packaging machinery to varying carton sizes by adjusting the rear stopper, eliminating the need to physically swap out the entire cylinder.
Heavy-Duty Clamping Setup
Leverage the 4523N push force to securely clamp materials while precisely controlling the clamping depth via the 50mm adjustment range.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-50S the Right Cylinder?
Choose this 80mm bore cylinder when your application requires up to 4523N of push force at 0.9MPa and significant on-the-fly stroke modification. If you need less force, stepping down to the 50mm bore yields 1767N, while the 100mm bore offers 7068N for heavier loads. The adjustable 50-100mm window is ideal for product changeovers, whereas a fixed SAI cylinder locks you into a single 100mm end position.
Because the rear adjuster only sets the end position and does not hold the load without live air, use a SAIL or BSAI cylinder if your application requires fail-safe load holding. This SAIJ80X100-50-S features PT tapered ports and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80BX100-50S FAQ
The rear adjusting screw allows you to shorten the effective stroke by up to 50mm, providing a usable travel window of 50-100mm. This lets you fine-tune the end position at commissioning without changing the cylinder or adding external stops.
No, the rear adjuster acts only as a travel stop and the air cushions only decelerate the motion; neither can hold a load without live air. For fail-safe load holding, consider the SAIL or BSAI cylinder series.
