About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-40S
The AirTAC SAIJ100X600-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 600 mm nominal stroke that can be dialed back by up to 40 mm, providing a usable travel window of 560 to 600 mm. Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore actuator handles heavy loads while allowing precise end-position tuning during commissioning without swapping cylinders. The PT tapered port threads ensure a tight, leak-free pneumatic connection.
Because this unit includes the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position and relies on the integrated air cushions for end-of-stroke deceleration; it does not lock or hold the load without continuous live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-40S Is Used
Product Size Changeover
Quickly reconfigure the 560-600 mm travel window on packaging lines handling varying box dimensions, using the rear adjuster to set new retract limits without changing the physical actuator.
Machine Setup Calibration
Fine-tune the end-stop position during initial commissioning of heavy machinery, dialing in the exact 40 mm adjustment to perfect tooling alignment without adding external stopper blocks.
Variable End-Stop Positioning
Control large automated doors or heavy material handling gates where the fully retracted position needs occasional adjustment, relying on the 3927 N thrust to move the load efficiently.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-40S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust, stepping up from a 63 mm bore that provides 1559 N of push force at 0.5 MPa, or scaling down from a 125 mm bore that yields 6136 N. The adjustable 560-600 mm travel window is ideal for production lines that undergo frequent product-size changeovers, allowing operators to set variable end-stops on the fly instead of adding external stops. When replacing an ISO 15552 cylinder, match the 100 mm bore, 600 mm stroke, 40 mm adjustment, G1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Given the 600 mm stroke on this model, the M20x1.5 rod and standard carbon steel construction will experience amplified side-load stresses if the load is unsupported. Always guide the load externally to prevent premature seal wear and rod bending. The rear mechanical stopper and air cushions manage end-position tuning and deceleration, but an external rod lock or pilot-operated check valve is required to hold the load safely without live air.

- ✓ 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 SAIJ100X600-40S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf of thrust.
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the 600 mm nominal stroke by up to 40 mm, creating a usable travel window of 560 to 600 mm. It sets the end position but does not lock the load without live air pressure.
