About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX80-30S
The AirTAC SAIJ50X80-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 982N of push force and 825N of pull force at 0.5 MPa. The built-in adjustment mechanism allows you to shorten the nominal 80mm stroke by up to 30mm, creating a precise 50-80mm usable travel window for exact end-position tuning during commissioning.
This variant includes a magnet for position sensing with CMSE reed or DMSE electronic switches. It uses a SUS420J2 stainless steel rod for corrosion resistance and features PT tapered G1/4 ports. The extruded aluminum barrel incorporates sensor grooves on both sides. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX80-30S Is Used
Machine Changeover
Dial in the 50-80mm travel window during product size transitions without adding external physical stops to your machinery.
End-Position Tuning
Fine-tune the exact retraction point at commissioning to perfect a 982N push operation, avoiding the need to remount the actuator.
Variable Diverter Stops
Adjust the stroke length on the fly to handle different package sizes on a packaging line, ensuring precise physical positioning.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX80-30S the Right Cylinder?
Choose this 50mm bore adjustable-stroke cylinder when your application requires variable end-stops or frequent product changeovers without swapping out the entire actuator. The 30mm adjustment window is ideal for tuning a 50-80mm travel distance on the fly. If your setup requires less force, stepping down to a 40mm bore yields 628N push at 0.5MPa. For heavier loads, a 63mm bore provides 1559N.
Remember that the rear adjuster acts as a mechanical stop to decelerate the travel end, not a lock. This plain SAIJ cylinder will not hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series. To replace this ISO 15552 cylinder, match the 50mm bore, 80mm stroke, 30mm adjustment, PT G1/4 port, and the -S magnet requirement.

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50AX80-30S FAQ
At 0.5 MPa operating pressure, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At the maximum 1.0 MPa pressure, it achieves 200 kgf.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back from the 80mm nominal stroke down to 50mm. This creates a 50-80mm usable travel window for fine-tuning the end position at commissioning without changing the cylinder.
