About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-30S
The AirTAC SAIJ100X350-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 350mm stroke that can be trimmed back by up to 30mm, giving you a precise 320-350mm usable travel window for exact end-position tuning during commissioning. Equipped with a standard magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state electronic sensors housed in the dual-side extruded aluminum barrel grooves.
Operating at 0.5 MPa, this 100mm bore generates 3927N of push force and 3681N of pull force, escalating to 7068N push at 0.9 MPa. The robust 25mm carbon steel piston rod and M20x1.5 rod thread handle substantial loads, but with a 350mm stroke, an external guide is recommended to prevent side-load wear on the rod seals.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-30S Is Used
Product Changeover Tuning
Dial in the 320-350mm travel window instantly on the factory floor to accommodate varying package sizes without replacing the actuator.
Assembly Press End-Stop
Leverage the 3927N thrust at 0.5 MPa for pressing operations while fine-tuning the final position to 0.1mm accuracy via the rear screw.
Diversion Gate Actuation
Adjust the stroke on-site to perfectly time diversion gates for different product profiles moving down the conveyor line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-30S the Right Cylinder?
Selecting this adjustable model over a fixed-stroke SAI cylinder makes sense when you need variable end-stops for product-size changeovers on a line without physically swapping the cylinder or bolting on external stops. If your application requires less force, stepping down to an 80mm bore yields 2513N push at 0.5 MPa, whereas moving up to a 125mm bore provides 6136N. Remember that the rear adjuster is a travel stop, not a locking mechanism; a plain SAIJ cannot hold a load without live air pressure. For fail-safe load holding, consider an SAIL pneumatic lock or BSAI clamp-lock cylinder.
To match this ISO 15552 footprint exactly, specify a 100mm bore, 350mm nominal stroke, 30mm adjustment range, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, deliberately omitting the FB, CA, CB, and CR variants found on some other series.
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 SAIJ100 Adjustable Cylinder SAIJ100X350-30S FAQ
At a standard 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. If pressure is increased to 0.9 MPa, the push force reaches 7068N.
The rear adjuster acts as an external stopper that allows you to shorten the 350mm nominal stroke by up to 30mm, creating a usable travel window of 320-350mm. It only sets the end position and does not lock the load without live air pressure.
