Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 350mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10S
The AirTAC SAIJ100X350-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers substantial thrust, pushing 5497N at 0.7MPa, while its 350mm nominal stroke can be precisely dialed back by up to 10mm. This creates a 340-350mm usable travel window, allowing you to fine-tune the retract end position at commissioning without adding external stops. Equipped with a -S magnet, it supports AirTAC CMSE reed and DMSE electronic sensors mounted in the dual-side extruded barrel grooves.
Because the 350mm stroke is long relative to the 25mm rod diameter, an external guide is recommended to prevent excessive side-load wear. The rear adjuster acts purely as a travel stop and deceleration point alongside the adjustable air cushions; it does not hold the load without live air. For true load-holding without pneumatic pressure, consider an external rod lock or the AirTAC SAIL series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10S Is Used
Machine Setup & Changeover
Fine-tune the 340-350mm retract position during product line changeovers without disassembling the cylinder or adding external mechanical stops.
Heavy Pressing Operations
Leverage the 5497N push force at 0.7MPa for heavy pressing or forming tasks that require precise end-position tuning.
Long-Travel Sorting
Actuate long-travel sorting gates on conveyors where a 10mm end-position adjustment accommodates varying package sizes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10S the Right Cylinder?
Choose this 100mm bore when your application requires heavy force (5497N push at 0.7MPa) that exceeds the 2182N push of a 63mm bore, but does not demand the massive 8590N output of a 125mm unit. The adjustable-stroke design is ideal for machine setups requiring variable end-stops or quick product changeovers. Unlike a fixed-stroke SAI cylinder, the SAIJ lets you trim the retract position by 10mm in place.
When replacing an ISO 15552 cylinder, match the 100mm bore, 350mm stroke, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). The carbon steel rod handles standard loads, but for the 350mm stroke, ensure your external guide supports the rod to maximize seal life.
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 SAIJ100X350-10S FAQ
At 0.7MPa operating pressure, this 100mm bore cylinder provides a push force of 5497N and a pull force of 3681N. It can reach a maximum push force of 7068N at 0.9MPa.
A rear external screw stopper allows you to shorten the effective stroke by up to 10mm, providing a usable travel window of 340-350mm. The adjuster sets the retract end position but does not lock the load without live air pressure.
