About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X135-20S
The AirTAC SAIJ200X135-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the nominal 135 mm stroke to create a precise 115-135 mm usable travel window. Built to handle massive loads, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa. The included magnet (-S) enables seamless position detection with AirTAC CMSE reed and DMSE electronic sensors.
This 200 mm bore unit features a robust 40 mm carbon steel rod with an M36x2 thread, providing exceptional resistance against bending under heavy loads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting, while the PT tapered port threads ensure a secure, leak-free pneumatic connection at the G3/4 ports.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X135-20S Is Used
Heavy Stamping Alignment
Fine-tunes the 115-135 mm travel window during heavy stamping setups, ensuring precise bottom-dead-center alignment without machining new stopper blocks.
Product Size Changeovers
Accelerates production line changeovers by allowing operators to quickly dial in the rear stroke adjuster to accommodate varying large-format product dimensions.
Clamping Force Calibration
Regulates the extended end-position on heavy-duty clamping fixtures, preventing deformation by trimming the final 20 mm of travel accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X135-20S the Right Cylinder?
Selecting this 200 mm bore cylinder is necessary when your application requires extreme thrust, such as 21991 N at 0.7 MPa, and on-the-fly end-position tuning without swapping hardware. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may simplify your air consumption. This SAIJ model is chosen over a fixed-stroke SAI when product changeovers demand a variable end-stop, letting you trim up to 20 mm of travel directly at the rear screw during commissioning.
Because the nominal stroke is 135 mm, the 40 mm rod is well-supported without needing external guides, though the rear adjuster acts strictly as a travel stop and not a lock. For load-holding without live air pressure, you must integrate an external pilot-operated check valve or switch to an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable unit exactly, specify: 200 mm bore, 135 mm stroke, 20 mm adjustment, PT G3/4 ports, a Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting style, and the -S magnet option.
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 SAIJ200 Adjustable Cylinder SAIJ200X135-20S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At a maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
The rear adjuster screw lets you shorten the 135 mm nominal stroke by up to 20 mm, creating a usable travel window of 115-135 mm. This allows for fine-tuning the retract end-position at commissioning without adding external stops.
