About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-50S
The AirTAC SAIJ80X100-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 100 mm nominal stroke that can be fine-tuned down by up to 50 mm, yielding a highly versatile 50-100 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it handles substantial loads while allowing precise end-position calibration during machine commissioning.
This model includes a standard carbon steel rod with an M20x1.5 thread, paired with a PT tapered port. The extruded aluminum barrel integrates sensor grooves on both sides for CMSE and DMSE switches, and the rear adjuster acts purely as a mechanical stop for deceleration and positioning, not as a lock to hold loads without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-50S Is Used
Product Changeover
Dial in the 50-100 mm travel window instantly when switching product sizes on a packaging line, avoiding mechanical cylinder swaps.
End-Stop Calibration
Fine-tune the retract end-position during machine commissioning to perfect pressing or clamping depth without external stops.
Variable Positioning
Set precise travel limits for assembly stations where the exact end-point distance varies between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-50S the Right Cylinder?
Choose this 80 mm bore when you need higher force than the 50 mm bore option (which provides 982 N push at 0.5 MPa) but want to avoid the larger footprint of a 100 mm cylinder (3927 N). The 50 mm adjustment range on this 100 mm stroke is ideal for product-size changeovers, letting operators dial in the exact end-stop without swapping the cylinder or adding external stops.
For load-holding applications without continuous air pressure, note that this cylinder's adjuster will not lock the position; you should instead look at the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 80 mm bore, 100 mm stroke, 50 mm adjuster, PT port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface. This -S variant includes the magnet for CMSE reed and DMSE electronic sensors.

- ✓ 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 SAIJ80X100-50S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the 100 mm nominal stroke by up to 50 mm, creating a 50-100 mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a lock; load-holding requires live air or a SAIL/BSAI lock cylinder.
