About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-100S
The AirTAC SAIJ100X115-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3927 N push force at 0.5 MPa, utilizing a 25 mm carbon steel rod core enhanced with a SUS420J2 stainless steel overlay (code A) for superior corrosion resistance. The integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE solid-state sensors housed within the dual-side barrel grooves.
This configuration provides an exceptionally wide usable travel window of 15 to 115 mm, allowing you to dial back the nominal stroke by up to 100 mm. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end-position during commissioning or product changeovers without swapping the cylinder. It is not a locking device, so load-holding without live air requires a SAIL or BSAI variant.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-100S Is Used
Changeover Calibration
Dial in the exact retract distance from 15 to 115 mm during product size changeovers without disassembling the machine or adding external stopper blocks.
Variable End-Stop Forming
Set precise end-of-stroke limits for pressing or forming operations where material thickness varies, using the 100 mm adjuster screw to tune the final position.
Sensor-Driven Sorting
Leverage the built-in magnet for DMSE electronic sensors to confirm rod position while adjusting the stroke window to accommodate different package dimensions on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-100S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm bore steps the thrust up from 2513 N to 3927 N at 0.5 MPa, providing the necessary force for heavier actuation. The massive 100 mm adjustment range is ideal for prototyping or production lines running mixed product sizes, replacing the need to stock multiple fixed-stroke SAI cylinders. Note that the PT tapered port threads and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) dictate specific manifold and bracket preparation.
Because the 115 mm stroke is relatively short, side-load risks are minimal, but the 25 mm rod thread still handles high off-center loads well. For any application requiring the cylinder to hold position safely without continuous air pressure, you must add an external rod lock or switch to a SAIL pneumatically-released lock cylinder, as the rear adjuster only sets the travel end.
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 SAIJ100AX115-100S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. It can achieve up to 7068 N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the 115 mm nominal stroke down to as little as 15 mm. This creates a 15-115 mm adjustable window for fine-tuning the end position at commissioning without replacing the cylinder.
