About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-50
The AirTAC SAIJ80X230-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 180 to 230 mm, letting you dial back the nominal 230 mm stroke by up to 50 mm during commissioning. This bore delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it suitable for medium-to-heavy actuation tasks.
The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without adding external stops. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though this specific SKU omits the internal magnet.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-50 Is Used
Product Changeover
Quickly adjust the 180-230 mm travel window to accommodate different package sizes on a packaging line without swapping out the entire actuator.
End-Position Tuning
Fine-tune the exact retract position during machine commissioning to prevent mechanical crashes and dial in precise locating datum points.
Variable End Stops
Set custom stroke limits on automated test fixtures where the effective travel distance needs periodic adjustment based on the test parameters.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-50 the Right Cylinder?
Choose this 80 mm bore when a 63 mm cylinder lacks thrust; stepping up from a 63 mm bore increases your 0.5 MPa push force from 1559 N to 2513 N. An adjustable-stroke cylinder is selected over a fixed SAI when you need variable end-stops for machine setup or product changeovers. To match this ISO 15552 footprint for replacement, verify the 230 mm stroke, 50 mm adjustment, PT tapered port thread, and standard carbon steel rod.
Because the stroke is 230 mm, the 25 mm rod and M20x1.5 thread provide good rigidity, but an external guide is recommended if carrying heavy lateral loads. Remember that the rear adjuster and air cushions only decelerate the travel end; a plain SAIJ does not hold loads without live air, so consider a SAIL or BSAI cylinder for fail-safe locking.
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 SAIJ80X230-50 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 delivers a push force of 4523 N.
The rear adjuster screw lets you mechanically shorten the effective stroke from the nominal 230 mm down to 180 mm. This creates a 50 mm adjustable travel window for fine-tuning the retract end position without changing the cylinder.
