About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX150-10
The AirTAC SAIJ50X150-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 150 mm travel by up to 10 mm. This creates a precise 140-150 mm usable window for fine-tuning end positions at commissioning without swapping out the unit. Delivering 982 N of push thrust at 0.5 MPa, it fits perfectly into medium-force pneumatic setups.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT (tapered) port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE or DMSE switches if position feedback is later required. The rear adjuster acts strictly as a travel stop for deceleration and positioning, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX150-10 Is Used
Machine Changeover
Quickly adapt the 140-150 mm travel window during product size changeovers on a packaging line without replacing the cylinder or adding external shims.
End-Position Tuning
Fine-tune the retract stop during commissioning to perfectly seat components, absorbing minor mechanical tolerances in the fixture.
Variable Diverter Stop
Adjust the actuator's end-stop on the fly to handle different carton sizes on a conveyor diverter mechanism.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX150-10 the Right Cylinder?
Selecting this 50 mm bore over a smaller 40 mm variant steps your push force up from 628 N to 982 N at 0.5 MPa, whereas moving to a 63 mm bore would yield 1559 N. The adjustable stroke is chosen when a fixed-stroke SAI cylinder cannot accommodate minor mechanical variances or product changeovers, letting you set a variable end-stop on the fly. Remember that a plain SAIJ does not hold its position without live air; for fail-safe load holding, consider the SAIL or BSAI series.
To replace an ISO 15552 cylinder, match the 50 mm bore, 150 mm stroke, 10 mm adjustment range, PT ports, and the standard mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the stroke is 150 mm, side loads are minimal, but always ensure the M16x1.5 rod thread is properly aligned with your external guide to prevent binding.

- ✓ 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 SAIJ50AX150-10 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 140-150 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At a 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push thrust and 825 N of pull thrust. At the maximum 1.0 MPa pressure, the push force reaches 1963 N.
