About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-30S
The AirTAC SAIJ100X300-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927N of push force at 0.5MPa and features a 300mm nominal stroke that can be fine-tuned down by up to 30mm, creating a precise 270-300mm usable travel window for product changeovers. The integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors, fitting directly into the extruded aluminum barrel's dual sensor grooves.
Because the stroke extends to 300mm, the 25mm carbon steel rod and M20x1.5 thread should be guided externally to prevent excessive side-loading. The rear adjuster acts purely as a travel stop to decelerate the end position alongside the 36mm air cushions; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-30S Is Used
Machine Changeover
Dial in the 270-300mm travel window during product size transitions without replacing the cylinder or adding mechanical shims.
End-Stop Tuning
Fine-tune the final retract position at commissioning using the rear screw, working in tandem with the 36mm air cushions for smooth deceleration.
Heavy Push Assembly
Leverage the 3927N push force at 0.5MPa for heavy-duty pressing operations while maintaining ISO 15552 mounting interchangeability.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-30S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (2513N push at 0.5MPa) is insufficient but a 125mm bore (6136N) would overcomplicate the machine footprint. The 30mm adjustment range is ideal for applications requiring variable end-stops during commissioning, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. To match this exact configuration for an ISO 15552 replacement, specify a 100mm bore, 300mm stroke, 30mm adjustment, PT tapered port threads, and a magnet for sensors.
For any 300mm stroke or longer, an external guide is highly recommended to support the rod and prevent binding under side loads. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ100X300-30S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm from the 300mm nominal length, providing a 270-300mm travel window. It functions as a physical stop to set the end position and does not lock the load without continuous air pressure.
At 0.5MPa, it provides 3927N of push force and 3681N of pull force. The operating speed range is 30-800mm/s, and it features a G1/2 port with a 25mm rod thread.
