About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-30
The AirTAC SAIJ80X230-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 200 to 230 mm usable travel window, allowing you to trim the effective stroke by up to 30 mm during commissioning without swapping hardware. Built with an extruded aluminum barrel, it is dimensionally interchangeable with ISO 15552 cylinders.
Driven by a 25 mm carbon steel rod and M20x1.5 thread, this 80 mm bore generates 3518 N of push force at 0.7 MPa. It uses a PT G3/8 port and reaches speeds of 30-800 mm/s. The rear screw acts purely as a mechanical stop for end-position tuning, so it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-30 Is Used
Changeover Calibration
Dial in the 200-230 mm travel window during product size changeovers to perfectly align stops without machining new mounting plates.
End-Position Tuning
Fine-tune the retract end position by up to 30 mm during machine commissioning to absorb mechanical tolerances and ensure precise seating.
Variable Stops
Provide adjustable physical stops for diverter arms or pushers on a conveyor line, allowing quick format adjustments for different package lengths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-30 the Right Cylinder?
Select this 80 mm bore when an application requires 3518 N push force at 0.7 MPa but needs precise end-position tuning across a 200-230 mm window. If your setup needs less force, stepping down to a 63 mm bore yields 2182 N. The adjustable stroke is ideal for product changeovers, whereas a fixed SAI cylinder suits static stops. For load-holding without air, use a SAIL or BSAI variant.
For ISO 15552 replacement matching, specify an 80 mm bore, 230 mm stroke, 30 mm adjustment, PT G3/8 port, and carbon steel rod. Since the 230 mm stroke exceeds 300 mm only marginally, side-load risk is low, but external guides remain recommended for heavy lateral loads. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80X230-30 FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder generates 3518 N of push force and 2268 N of pull force. At 0.5 MPa, it provides 2513 N push and 2268 N pull.
The rear adjuster screw lets you shorten the 230 mm nominal stroke by up to 30 mm, creating a 200-230 mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a locking device.
