About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-75S
The AirTAC SAIJ80X100-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 25 to 100 mm. Fitted with a standard carbon steel rod and a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves. Delivering a robust 2513 N pull force at 0.5 MPa, it handles heavy dynamic loads with precision.
This adjustable model lets you fine-tune the retract end-position at commissioning without adding external stops. The rear screw acts purely as a travel stop and does not hold the load without live air; for dead-end locking, consider the SAIL or BSAI series. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and PT tapered G3/8 ports.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-75S Is Used
Machine Changeover
Dial in the exact retract position from 25 to 100 mm during product size transitions without swapping out the physical cylinder.
End-Stop Tuning
Fine-tune the final end-position at commissioning using the rear adjuster screw to perfect machine timing and physical stops.
Variable Stroke Assembly
Handle varying part heights on a single line by adjusting the effective stroke window on the fly for precise pressing operations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-75S the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N pull at 0.5 MPa) is insufficient but 100 mm (3681 N pull) is overkill. The 75 mm adjustment range is ideal for product-size changeovers, letting you dial back the 100 mm nominal stroke down to 25 mm on the fly. Because the adjuster only restricts travel, remember it is not a lock; position holding without live pressure requires a SAIL or BSAI cylinder, or an external rod lock.
When matching your ISO 15552 replacement, verify the 80 mm bore, 100 mm stroke, 75 mm adjustment, PT G3/8 ports, and the -S magnet option. The 25 mm rod and M20x1.5 thread handle high side loads, but for any stroke over 300 mm, always use an external guide to prevent rod binding.

- ✓ 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 SAIJ80X100-75S FAQ
The rear adjuster screw acts as an external stop, allowing you to shorten the effective stroke from the nominal 100 mm down to 25 mm, creating a 25-100 mm usable travel window. It functions as a travel stop, not a lock, so it will not hold the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ80X100-75-S provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it delivers 4523 N of push force.
