About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-75S
The AirTAC SAIJ80X1000-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa, utilizing a G3/8 PT tapered port and a 25mm carbon steel rod. Because this is an extended 1000mm stroke unit, the external adjuster allows you to dial back the effective travel by up to 75mm, creating a precise 925-1000mm usable window without needing external stops.
This model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the dual-side sensor grooves on the extruded aluminum barrel. The rear screw acts purely as a travel stop for end-position tuning during commissioning; it does not lock the load, meaning live air is required to hold position. For load-holding without air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-75S Is Used
Long-Stroke Conveyor Diverter
Fine-tune the 925-1000mm retract stop during line changeovers to handle different pallet sizes without physically replacing the actuator.
Equipment Commissioning
Dial in the exact end-of-stroke position during machine setup using the rear 75mm adjuster, avoiding the need to machine custom external spacers.
Large Assembly Press
Leverage the 2513N push force at 0.5 MPa to seat heavy components, using the adjustable stop to accommodate varying product heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-75S the Right Cylinder?
Choose this 80mm bore when an application requires more thrust than a 63mm cylinder (1559N push at 0.5 MPa) but less than a 100mm bore (3927N). The adjustable 925-1000mm travel window is ideal for product changeovers on long-stroke lines, letting you fine-tune the retract end position without swapping the cylinder. To match this ISO 15552 cylinder for a retrofit, confirm the 80mm bore, 1000mm nominal stroke, 75mm adjustment, G3/8 PT port, and the -S magnet option.
Because the stroke is 1000mm, the 25mm rod and M20x1.5 rod thread provide structural rigidity, but an external guide is strongly recommended to prevent excessive side-loading on the piston. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets. Operating speed ranges from 30-800 mm/s.
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 SAIJ80X1000-75S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force increases to 4523N.
The rear adjuster screw allows you to shorten the 1000mm nominal stroke by up to 75mm, providing a usable travel window of 925-1000mm. It functions as a mechanical stop for end-position tuning and requires live air to hold the load.
