About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50S
The AirTAC SAIJ80X600-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 550-600 mm usable travel window, allowing you to dial back the 600 mm nominal stroke by up to 50 mm during commissioning. This bore delivers 2513 N of push force at 0.5 MPa and integrates a SUS420J2 stainless steel rod for enhanced corrosion resistance.
Equipped with a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic solid-state switches. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered G3/8 ports ensure a tight, leak-free pneumatic connection.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50S Is Used
Variable End-Stop Tuning
Dial in the exact 550-600 mm retract position during machine commissioning without physically swapping the cylinder or adding bulky external stopper blocks.
Product Size Changeover
Quickly adapt a long-stroke pushing station to handle different package lengths by adjusting the rear screw up to 50 mm on the fly.
Long-Stroke Assembly Press
Leverage the 2513 N push force at 0.5 MPa to seat large components, using the rear stopper to precisely limit the 600 mm travel and prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust (2513 N push at 0.5 MPa) but demands a non-standard 600 mm stroke with a 50 mm adjustment range. If you need less force, the 63 mm bore offers 1559 N; if you require more, the 100 mm bore provides 3927 N. The rear adjuster acts purely as a travel stop to fine-tune the end position without adding external blocks, but it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
Because the 600 mm stroke is long, the 25 mm rod diameter and M20x1.5 thread will still experience leverage forces; an external guide rail is recommended to prevent side-loading damage. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) to fit your existing fixtures.
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 SAIJ80 Adjustable Cylinder SAIJ80AX600-50S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from 600 mm down to 550 mm. It trims the end position but does not lock the load without live air pressure.
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. Its operating speed range is 30-800 mm/s, driven by its G3/8 ports.
