About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX130-30S
The AirTAC SAIJ50X130-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 982N of push force and 825N of pull force at 0.5 MPa. The external stopper allows you to trim the nominal 130mm stroke back by up to 30mm, providing a precise 100-130mm usable travel window for fine-tuning end positions during commissioning. This eliminates the need to swap cylinders or add external stops when dialing in a machine.
Equipped with a SUS420J2 stainless steel rod and PT tapered ports, this model features an integrated magnet for use with CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for load-holding applications, consider the SAIL or BSAI series.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX130-30S Is Used
Machine Changeover
Dial in the 100-130mm travel window during product size changes without swapping out the entire cylinder or adding external mechanical stops.
End-Stop Tuning
Fine-tune the exact retract position at commissioning to perfect the pickup or placement of delicate components using the rear adjustment screw.
Variable Diverter
Adjust the stroke on the fly to accommodate different package sizes on a conveyor line, ensuring precise routing without retooling.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX130-30S the Right Cylinder?
Choose this 50mm bore cylinder when your application requires 982N of push force at 0.5 MPa, offering a middle ground between the 40mm bore (628N) and the larger 63mm bore (1559N). The 30mm adjustment range is ideal for product changeovers or variable end-stop setups, providing a 100-130mm travel window without changing the cylinder itself. Unlike a fixed-stroke SAI cylinder, this adjustable model allows you to dial in the exact retract position on the fly.
For ISO 15552 replacement matching, ensure you specify the 50mm bore, 130mm stroke, 30mm adjustment, PT port thread, and the -S magnet option. Because the 130mm stroke is relatively short, side-loading is less of a concern, but the 20mm rod and M16x1.5 thread still handle moderate side loads effectively. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ50AX130-30S 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 delivers up to 200 kgf.
The rear adjuster screw acts as a mechanical stop that can shorten the nominal 130mm stroke by up to 30mm, giving you a usable travel window of 100-130mm. It only sets the end position and does not lock the load without live air.
