About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-50
The AirTAC SAIJ80X130-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5 MPa and features a 130mm nominal stroke that can be fine-tuned down by up to 50mm, creating a usable travel window of 80 to 130mm. This allows precise end-position calibration during commissioning without swapping hardware.
This extruded aluminum profile cylinder features a 25mm carbon steel piston rod and M20x1.5 rod thread, providing excellent resistance against side loads. It uses PT tapered port threads (G3/8) and supports adjustable air cushions at both ends to decelerate heavy loads smoothly. The rear stopper sets the travel limit but does not function as a lock, meaning live air pressure is required to hold the load in place.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-50 Is Used
Product Changeovers
Dial in the 80 to 130mm travel window rapidly during format size changes on packaging lines without changing out the cylinder body.
End-Stop Calibration
Fine-tune the exact retract position during machine commissioning to prevent crashes, using the rear adjuster rather than external stops.
Heavy Clamping Tasks
Leverage the 2513N push force at 0.5 MPa to secure heavy workpieces, relying on the adjuster to set the precise clamping depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-50 the Right Cylinder?
Select this 80mm bore cylinder when an application demands high thrust (2513N push at 0.5 MPa) alongside variable end-stop positioning. If your setup requires less force, stepping down to a 63mm bore yields 1559N; if you need significantly more push capacity, a 100mm bore provides 3927N. The adjustable 80 to 130mm travel window is perfect for product changeovers on a line, replacing the need to bolt on external stops or maintain multiple fixed-stroke SAI cylinders.
When matching an ISO 15552 replacement, verify the 80mm bore, 130mm nominal stroke, 50mm adjustment range, G3/8 PT ports, and mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder instead. Because this unit lacks the -S magnet option, it cannot host CMSE or DMSE sensors.

- ✓ 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 SAIJ80X130-50 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop that shortens the 130mm nominal stroke by up to 50mm, providing an effective travel range of 80 to 130mm. It only sets the travel end and does not lock the load without live air pressure.
