About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX600-20S
The AirTAC SAIJ50X600-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 580-600mm usable travel window from its 600mm nominal stroke. Delivering 982N of push force and 825N of pull force at 0.5MPa, it handles demanding positioning tasks. The extruded aluminum barrel incorporates sensor grooves on both sides for straightforward switch placement.
This variant uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors. It features PT tapered port threads and adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX600-20S Is Used
Machine Setup Tuning
Dial in the exact 580-600mm retract stop during initial commissioning to perfect product transfer timing.
Product Changeover
Quickly adapt the end-stop position on a packaging line when running different package lengths.
Variable End Stops
Fine-tune the stroke endpoint on the fly to accommodate minor variations in workpiece dimensions.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX600-20S the Right Cylinder?
Choose this 50mm bore when a 40mm bore (628N push at 0.5MPa) lacks thrust, but a 63mm bore (1559N) is oversized. The 20mm rear adjuster allows precise end-position tuning during commissioning or product changeover without adding external stops. Because the 600mm stroke is substantial, an external guide is recommended to manage side loads. For load-holding without live air pressure, select a SAIL or BSAI cylinder, as this adjuster is strictly a travel stop, not a lock. ISO 15552 mounting interfaces include 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 SAIJ50AX600-20S FAQ
At 0.5MPa it provides 982N push and 825N pull force, scaling to 1374N push at 0.7MPa.
A rear stopper screw lets you shorten the 600mm stroke by up to 20mm, creating a 580-600mm travel window for exact positioning.
