About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-30
The AirTAC SAIJ80X90-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that trims the nominal 90 mm travel back by up to 30 mm, creating a highly flexible 60-90 mm usable window. Delivering a robust 2513 N push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads for a mechanically sealed pneumatic connection.
Unlike a fixed-stroke SAI unit, this model allows technicians to dial in the exact retract end-position during commissioning or product changeovers without swapping the barrel or adding external stops. The extruded aluminum profile includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-30 Is Used
Machine Changeover
Dial in the 60-90 mm retract stop during product size transitions without replacing the cylinder or adding external mechanical stops.
Variable End-Positioning
Fine-tune the end-of-stroke point during commissioning to perfect the seating force of pressing or clamping assemblies.
Corrosive Environments
Leverage the SUS420J2 stainless steel rod and 2513 N thrust for robust actuation in washdown or mildly corrosive industrial settings.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-30 the Right Cylinder?
Choose this 80 mm bore when your application requires substantial thrust—stepping down to a 63 mm bore drops the 0.5 MPa pull force to 1402 N, whereas this SAIJ80X90-30 provides 2268 N. The 30 mm adjustment range is ideal for machinery requiring variable end-stops to accommodate different product sizes on a single line. For load-holding requirements without continuous air pressure, note that the adjuster is not a lock; consider an AirTAC SAIL or BSAI series instead. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 90 mm stroke is relatively short, side-load concerns are minimal, but an external guide is still recommended for heavy radial loads.
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 SAIJ80AX90-30 FAQ
The rear adjuster screw acts as a mechanical stop that shortens the 90 mm nominal stroke by up to 30 mm, providing a usable travel window of 60 to 90 mm. It decelerates the travel end but does not lock the load without live air pressure.
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. It operates at speeds between 30 and 800 mm/s, utilizing PT tapered G3/8 ports.
