About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX270-10
The AirTAC SAIJ50X270-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 982N push force at 0.5 MPa and features a 16mm piston rod with an M16x1.5 thread. The integrated rear stopper allows you to trim the nominal 270mm travel back by up to 10mm, creating a precise 260-270mm usable window for fine-tuning end positions during commissioning.
This variant utilizes a SUS420J2 stainless steel rod for enhanced durability against moisture and minor corrosion. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch mounting. Fluid supply is controlled via PT tapered G1/4 ports, while variable air cushions at both ends manage end-of-stroke deceleration.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX270-10 Is Used
Machine Setup Tuning
Dial in the exact 260-270mm end position during initial commissioning to perfect a pushing motion without machining custom spacers.
Product Changeover
Quickly adjust the retract stop by up to 10mm on a packaging line when switching to a slightly shorter product format.
Variable End Stops
Fine-tune the tooling contact point on an assembly fixture to compensate for mechanical wear over time.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX270-10 the Right Cylinder?
Choose this 50mm bore adjustable-stroke cylinder when a process requires exact 260-270mm end-position tuning without adding external stops or swapping components. If your application needs less force, the 40mm bore delivers 628N push at 0.5MPa; for higher force, the 63mm bore provides 1559N. Because the 270mm stroke is relatively long, an external guide is recommended to prevent rod sag and side-load damage.
The rear adjuster acts solely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. To match this ISO 15552 cylinder, specify the 50mm bore, 270mm stroke, 10mm adjustment, PT G1/4 port, and the SUS420J2 rod material. Mounting options are limited to 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 SAIJ50 Adjustable Cylinder SAIJ50AX270-10 FAQ
At 0.5 MPa, this 50mm bore cylinder provides a push force of 982N and a pull force of 825N. At 0.7 MPa, the push force increases to 1374N.
A rear stopper screw lets you shorten the 270mm nominal stroke by up to 10mm, providing a 260-270mm usable travel window. The adjuster is a mechanical stop, not a lock, so it cannot hold the load without live air pressure.
