About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-100S
The AirTAC SAIJ200X950-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering immense thrust up to 15708 N at 0.5 MPa. It features a robust 40 mm SUS420J2 stainless steel rod and PT tapered port threads. By utilizing the 100 mm adjustment mechanism, this model transforms its 950 mm nominal stroke into a highly versatile 850-950 mm usable travel window, allowing operators to dial in exact end positions without physical cylinder swaps.
Because the barrel is an extruded aluminum profile rather than a tie-rod design, it integrates dual sensor grooves on both sides for straightforward mounting of CMSE reed or DMSE electronic switches. The 100 mm stopper screw acts purely as a travel end-limit and deceleration boundary, meaning it will not hold the load if air pressure drops. For applications requiring true fail-safe load holding, an external rod lock or the AirTAC SAIL pneumatic locking series must be specified instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 850-950 mm end position during machine commissioning to ensure perfect pressing depth without swapping out the entire cylinder.
Product Size Changeovers
Quickly retract the end stop by up to 100 mm to accommodate varying pallet lengths on a heavy-duty conveyor line.
Large Assembly Station
Adjust the rear stopper to synchronize the travel end across multiple large-bore actuators during automated heavy assembly operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-100S the Right Cylinder?
Selecting this 200 mm bore over a 160 mm neighbor provides a significant force leap from 10053 N to 15708 N at 0.5 MPa, which is critical for driving heavy actuators or overcoming high friction. The adjustable 850-950 mm window is chosen over a fixed-stroke SAI cylinder when a machine requires fine-tuning during commissioning or when accommodating product size changeovers on the fly.
Given the 950 mm stroke exceeds the 300 mm threshold, the 40 mm rod requires an external guide rail to prevent excessive side-loading and premature seal wear. This SAIJ variant supports the reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552, uses PT ports, and includes the -S magnet for position sensing.

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 SAIJ200 Adjustable Cylinder SAIJ200AX950-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push thrust and 15080 N of pull thrust. It can achieve a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 950 mm nominal stroke by up to 100 mm, creating an 850-950 mm usable travel window. This stopper only sets the travel end and decelerates the piston; it does not lock or hold the load without live air pressure.
