About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-75S
The AirTAC SAIJ100X275-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 3927N of push force at 0.5 MPa and provides a usable travel window of 200 to 275mm. The integrated -S magnet supports position detection via AirTAC CMSE reed and DMSE solid-state sensors.
This adjustable-stroke design allows you to fine-tune the retract end-position at commissioning without adding external stops. The 25mm piston rod and M20x1.5 rod thread handle high side loads, while the extruded aluminum barrel incorporates sensor grooves on both sides. The standard carbon steel rod and PT tapered port threads ensure robust, leak-free pneumatic connections.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within a 200-275mm window during machine setup without swapping physical cylinders or adding external stopper blocks.
Product Changeover
Quickly adapt the stroke length on packaging lines when handling different carton sizes, using the 75mm rear adjustment screw to match new product dimensions.
High-Force Positioning
Leverage the 3927N push force at 0.5 MPa to move heavy pallets or fixtures, relying on the 25mm rod to withstand significant side loads during transit.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-75S the Right Cylinder?
Choose this 100mm bore cylinder when an application requires substantial thrust (3927N at 0.5 MPa) alongside variable end-stop positioning. If your setup only needs 1767N of push force, step down to the 50mm bore model. Because the 275mm stroke is relatively long, always use an external guide to support the load and prevent rod binding.
The 75mm adjustment window is ideal for product changeovers on a line, allowing you to dial back the stroke on the fly. Remember that the rear adjuster acts as a travel stop, not a lock; the SAIJ does not hold its position without live air. For true load-holding without pressure, select the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100X275-75S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75mm, providing a usable travel window of 200 to 275mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.5 MPa it provides 3927N push and 3681N pull force. The -S option includes a magnet for use with AirTAC CMSE reed switches and DMSE solid-state sensors via the dual-side barrel grooves.
