About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX270-100S
The AirTAC SAIJ50X270-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 170-270 mm from its 270 mm nominal stroke, allowing you to dial back the end position by up to 100 mm during commissioning. Belonging to the 50 mm bore class, it delivers 982 N of push force and 825 N of pull force at 0.5 MPa.
This unit includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and a magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. It operates at speeds of 30-800 mm/s and uses a PT tapered G1/4 port.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX270-100S Is Used
Variable Retract Stops
Dial in the exact retract position within the 170-270 mm window for precise end-of-stroke tuning without adding external mechanical stops.
Product Changeovers
Quickly adjust the stroke by up to 100 mm when switching product sizes on a conveyor line, reducing setup time between runs.
Machine Setup
Fine-tune the travel end point during initial commissioning to dial in the exact motion profile required for the process.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX270-100S the Right Cylinder?
Choose this 50 mm bore when you need 982 N of thrust at 0.5 MPa and require significant on-machine travel adjustment without swapping cylinders. If your application needs less force, the 40 mm bore offers 628 N; if you need more, the 63 mm bore provides 1559 N. The 100 mm adjustment range is ideal for product changeovers, letting you set a new retract stop quickly.
For a drop-in ISO 15552 replacement, match the 50 mm bore, 270 mm stroke, 100 mm adjustment, G1/4 PT port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is 270 mm, use an external guide to prevent side-loading on the rod. Remember, the rear adjuster is a hard stop, not a lock; for load-holding without live air, consider SAIL or BSAI models.
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 SAIJ50AX270-100S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 100 mm, providing a usable travel window of 170-270 mm. It sets the travel end and deceleration point but does not lock the load without live air pressure.
