About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75
The AirTAC SAIJ100X80-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 5-80 mm. Delivering 3927 N of push force at 0.5 MPa, it provides robust actuation for heavy loads. The barrel is extruded aluminum with sensor grooves on both sides for flexible positioning.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The rear adjuster acts as a travel stop to dial in end positions during commissioning, but it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75 Is Used
Product Changeover
Quickly adapt end-stops for different sized parts on a single production line without physically swapping cylinders or adding external mechanical stops.
Commissioning Calibration
Dial in the exact 5 to 80mm travel window during machine setup to perfectly time pressing or lifting motions without trial-and-error shimming.
Heavy Load Positioning
Leverage the 3927 N push force to move heavy assemblies into place, using the rear adjuster to fine-tune the final resting position to within a fraction of a millimeter.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75 the Right Cylinder?
Choose this 100mm bore cylinder when you need substantial thrust (3927 N push at 0.5 MPa) that exceeds the 2513 N offered by the 80mm bore, or step down if less force is required. The 75mm adjustment range is exceptionally wide, making it ideal for product changeovers on a line where end positions frequently vary by tens of millimeters, eliminating the need to swap out a fixed-stroke SAI cylinder.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 100mm bore, 80mm stroke, 75mm adjustment, PT port, and your required mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (FB, CA, CB, and CR are omitted). Because the stroke is under 300mm, side-load stress is manageable, but always guide long unsupported loads externally.
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 SAIJ100 Adjustable Cylinder SAIJ100BX80-75 FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw acts as an external stop that lets you mechanically shorten the nominal 80mm stroke down to a minimum of 5mm. It sets the travel end and deceleration point but does not lock the load without live air pressure.
