About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-75S
The AirTAC SAIJ80X600-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the 600 mm nominal travel back by up to 75 mm, yielding a 525-600 mm usable end-position window. Equipped with a SUS420J2 stainless steel rod and a PT tapered port, it delivers 2513 N of push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports AirTAC CMSE reed and DMSE electronic switches for precise position detection.
Because the rear screw acts purely as a travel stop and relies on the standard variable air cushion for end-of-stroke deceleration, it does not hold the load without live air pressure. For applications requiring true load-holding without continuous pneumatic pressure, an external rod lock or the related AirTAC SAIL locking cylinder is required. This model utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-75S Is Used
Product Size Changeovers
Dial in the exact 525 to 600 mm retract position during format changeovers on packaging lines without replacing the cylinder or shimming external stops.
Machine Setup Calibration
Fine-tune the end-of-stroke position during initial commissioning to perfectly seat heavy 80 mm bore assemblies against a workpiece.
Variable End-Stop Forming
Accommodate multiple part depths in a single forming station by adjusting the rear stopper within the 75 mm window to prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-75S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust, such as the 2513 N push force at 0.5 MPa, but does not need the full 3927 N push capacity of the 100 mm variant. The adjustable 525-600 mm window is ideal for production lines running multiple product sizes, allowing operators to fine-tune the retract end-stop during changeovers without swapping cylinders or adding external mechanical stops. To match this cylinder exactly as an ISO 15552 replacement, specify the 80 mm bore, 600 mm stroke, 75 mm adjustment, PT port thread, the required mounting bracket, and the -S magnet option.
Given the 600 mm stroke, the M20x1.5 piston rod must be adequately supported by an external guide to prevent excessive side-loading and premature seal wear. Remember that the rear adjuster only sets the travel limit; it functions as a stop, not a brake, so gravity or external forces can move the load if air pressure is removed.
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 SAIJ80AX600-75S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it achieves a peak push force of 513 kgf.
The rear adjuster screw allows you to shorten the 600 mm nominal stroke by up to 75 mm, creating a 525-600 mm usable travel window. The screw acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
