About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX90-10S
The AirTAC SAIJ80X90-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5 MPa while providing a usable travel window of 80 to 90mm, letting you dial in the exact end position during commissioning. The SUS304 stainless steel rod and PT tapered ports make it highly durable for demanding industrial environments.
Because this unit includes the -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors housed in the dual-side barrel grooves. The rear adjuster functions strictly as a mechanical stop to fine-tune the retract position, meaning it cannot hold a load without live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI locking variants.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX90-10S Is Used
Precision End-Stop Tuning
Dial in the exact retract position within the 80 to 90mm window during machine commissioning without changing the cylinder or adding external stops.
Product Size Changeovers
Quickly adjust the stroke by up to 10mm on packaging lines to accommodate varying product lengths on the fly.
Heavy-Duty Positioning
Leverage the 2513N push force at 0.5 MPa to move and position heavy fixtures while fine-tuning the final resting point.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX90-10S the Right Cylinder?
Choose this 80mm bore when an application requires more thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but without the larger footprint of a 100mm unit. The adjustable 10mm end-stop is perfect for setups requiring variable end positions or product-size changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. When replacing an ISO 15552 cylinder, match the 80mm bore, 90mm stroke, G3/8 PT ports, and the -S magnet requirement.
Although the 90mm stroke is relatively short, the 25mm rod diameter and M20x1.5 rod thread provide excellent structural rigidity. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR mounts. Operating speed ranges from 30 to 800mm/s, regulated by variable air cushions at both ends.
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 SAIJ80 Adjustable Cylinder SAIJ80BX90-10S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach up to 4523N push force at 0.7 MPa.
The rear mechanical adjuster acts as a stop, allowing you to shorten the nominal 90mm stroke by up to 10mm, creating an 80 to 90mm usable travel window. It is a travel stop, not a lock, so it will not hold the load without continuous air pressure.
