About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-50
The AirTAC SAIJ100X350-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 5497N of push force at 0.7MPa. It features a 25mm carbon steel piston rod and a G1/2 PT port. The built-in adjusting screw allows you to trim the effective travel, providing a usable stroke window of 300 to 350mm for precise end-position tuning.
This adjustable capability is ideal for product changeovers, letting you dial in the end stop without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though a magnet is not included in this standard configuration. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-50 Is Used
Machine Setup & Changeover
Fine-tune the retraction end position within the 300-350mm window during product line changeovers without physically replacing the actuator.
Variable End-Stop Positioning
Ideal for diverter gates or sorting mechanisms on a conveyor where the exact stopping point of the 25mm rod must be adjusted on the fly.
Heavy-Duty Forming Presses
Delivers 5497N of push force at 0.7MPa for clamping or pressing tasks, allowing the stroke length to be dialed back precisely for different material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-50 the Right Cylinder?
Select this 100mm bore cylinder when your application requires substantial thrust, stepping up from a 80mm bore that provides 3518N push force at 0.7MPa. The 50mm adjustment window is perfect for machinery that requires variable end stops during setup or product-size changes. Because this is an adjustable-stroke model, it offers superior commissioning flexibility compared to a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100mm bore, 350mm nominal stroke, 50mm adjustment range, G1/2 PT port, and mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the 350mm stroke is relatively long, ensure you provide an external guide to handle side loads, as the 25mm rod needs support over extended travel. For load-holding without live air, consider an external rod lock or a SAIL cylinder instead.
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 SAIJ100X350-50 FAQ
At an operating pressure of 0.7MPa, this 100mm bore cylinder provides a push force of 5497N and a pull force of 3681N. At 0.9MPa, the push force increases to 7068N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 350mm nominal stroke down to 300mm. It only sets the travel end and does not lock the load without continuous air pressure.
