About the Airtac SAIJ50 Adjustable Cylinder SAIJ50X600-75S
The AirTAC SAIJ50X600-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 525 to 600 mm usable travel window, allowing you to dial back the 600 mm nominal stroke by up to 75 mm during commissioning. Equipped with a -S magnet, it integrates seamlessly with CMSE reed and DMSE solid-state sensors housed in the dual-sided barrel grooves. The carbon steel piston rod features an M16x1.5 thread, and the body uses PT tapered port threading for the G1/4 connection. Delivering 982 N of push force at 0.5 MPa, it handles variable air cushions at both ends to decelerate heavy loads.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning end positions. The rear screw acts purely as a travel stop and relies on live air to hold the load; for pilot-operated check valve or mechanical load-holding, consider the SAIL or BSAI series. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50X600-75S Is Used
Variable End-Position Tuning
Dial in the exact retract distance from 525 to 600 mm during machine commissioning without replacing the cylinder or adding external hard stops.
Product Size Changeover
Quickly adapt the stroke length on packaging lines handling varying container sizes by adjusting the rear stopper up to 75 mm.
Sensor-Driven Automation
Leverage the built-in magnet for CMSE and DMSE switches to confirm end-stroke positions dynamically as the effective travel changes.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50X600-75S the Right Cylinder?
Choose this 50 mm bore cylinder when your application requires 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa) and a highly variable end-stop. If you need less force, stepping down to a 40 mm bore yields 628 N, whereas stepping up to a 63 mm bore provides 1559 N. The adjustable 75 mm window is ideal for product changeovers, allowing you to reposition the retract stop without machining new hard stops.
Because the 600 mm stroke is substantial, the M16x1.5 carbon steel rod can experience side-loading forces; an external guide is recommended to prevent premature seal wear. This SAIJ model is dimensionally interchangeable per ISO 15552, featuring a PT tapered port, and is not a substitute for a fixed-stroke SAI cylinder if your setup never requires travel adjustments. The rear adjuster and air cushions decelerate motion but do not lock the load without continuous air pressure.
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 SAIJ50X600-75S 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 screw lets you shorten the 600 mm nominal stroke by up to 75 mm, creating a 525 to 600 mm usable travel window. The adjuster acts as a travel stop and does not lock the load without live air pressure.
