About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-50S
The AirTAC SAIJ200X140-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position. It provides a usable travel window of 90-140 mm, letting you dial back the nominal 140 mm stroke by up to 50 mm during commissioning without adding external stops. Built to deliver immense thrust, it generates 15080 N of pull force at 0.5 MPa and up to 3204 kgf at 1.0 MPa.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced durability against moisture and light corrosion. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. PT tapered ports (G3/4) and a robust 40 mm rod diameter ensure high structural integrity for heavy-duty operations.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-50S Is Used
Variable End-Stop Tuning
Perfect for heavy press operations where the exact bottoming position must be dialed in within a 90-140 mm window during setup or product changeover.
Machine Changeover
Allows operators to quickly adjust the retract distance on a packaging or forming line without physically swapping out the entire cylinder.
Heavy-Duty Positioning
Ideal for moving large assemblies on a conveyor, relying on the 3204 kgf max force and DMSE electronic sensors for reliable feedback.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-50S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires massive force output alongside a variable end-stop. If you need less thrust, stepping down to a 160 mm bore yields 9425 N of pull force at 0.5 MPa, which may be more efficient and lighter. Conversely, if your machine setup demands exact end-position tuning during product changeovers, this adjustable-stroke model is superior to a fixed-stroke SAI cylinder.
Because the nominal stroke is 140 mm, an external guide is not strictly required for side-load support, but the heavy 40 mm rod thread (M36x2) handles substantial loads. Remember that the rear adjuster acts only as a travel stop, not a locking device; it will not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. This SAIJ model uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR mounts.
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 SAIJ200AX140-50S FAQ
This 200 mm bore cylinder delivers a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At its maximum operating pressure of 1.0 MPa, it can generate up to 3204 kgf of thrust.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 140 mm down to 90 mm. It provides a 50 mm tuning window for precise end-positioning at commissioning, but it is not a lock and cannot hold a load without live air pressure.
