About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX50-10
The AirTAC SAIJ80X50-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 2513N of push force at 0.5 MPa and provides a usable travel window of 40-50mm, letting you trim up to 10mm off the nominal 50mm stroke during commissioning. This eliminates the need for external stopper blocks when dialing in final end positions.
Built with an SUS420J2 stainless steel rod (option A) for corrosion resistance, it uses a PT tapered port and supports speeds of 30-800mm/s. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE solid-state switches later if position feedback is required.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX50-10 Is Used
Machine Setup Calibration
Fine-tune the 40-50mm travel window during commissioning to perfectly set the end-of-stroke position without adding external stopper hardware.
Product Changeover
Quickly adjust the retract end-stop by up to 10mm when switching between slightly different product sizes on a packaging line.
Assembly Positioning
Leverage the 2513N push force at 0.5MPa to drive heavy pressing operations while retaining the flexibility to dial back the stroke.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX50-10 the Right Cylinder?
Choose this 80mm bore when a 63mm cylinder lacks thrust, as stepping down to a 63mm bore drops the 0.5MPa push force to 1559N. The adjustable stroke is perfect for machine setups requiring variable end stops or product-size changeovers, avoiding the hassle of swapping out a fixed-stroke SAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air pressure. For true load-holding, consider an external rod lock or pilot-operated check valve. To match ISO 15552 interchangeability, specify an 80mm bore, 50mm stroke, 10mm adjustment, PT port, and no magnet.
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 SAIJ80AX50-10 FAQ
At 0.5MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. If operated at 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective travel from 50mm down to 40mm, creating a 40-50mm usable window. It acts as a mechanical stop to fine-tune the end position without replacing the cylinder.
