About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-50S
The AirTAC SAIJ200X135-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 85-135 mm from its 135 mm nominal stroke. As an extruded aluminum barrel design, it is dimensionally interchangeable per ISO 15552 without being a tie-rod type. It delivers exceptional power, providing 15708 N of push force and 15080 N of pull force at 0.5 MPa. This specific configuration includes a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and PT tapered port threads.
The rear adjuster acts as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is a travel stop, not a lock, so it will not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. This -S model includes a magnet for use with AirTAC CMSE reed and DMSE electronic sensors mounted in the dual-side sensor grooves.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-50S Is Used
Heavy Press Tuning
Dial in the exact retract position of a high-tonnage press during setup. The 85-135 mm window allows operators to adjust the 50 mm stopper without swapping cylinders between product runs.
Large Package Diverter
Handle heavy pallets by adjusting the diverting stroke on the fly. The 200 mm bore provides 15708 N of push force to move heavy loads smoothly into sorting lanes.
Automated Assembly Stops
Fine-tune the end-stop position for large automotive sub-assemblies. The rear adjuster sets the exact 85-135 mm travel limit while the SUS420J2 rod resists harsh plant environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-50S the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when an application requires the 15708 N push force at 0.5 MPa, as stepping down to a 160 mm bore drops the push force to 10053 N. The 50 mm adjustment range is ideal for machinery requiring precise variable end-stops during product changeover, offering more tuning flexibility than a fixed-stroke SAI cylinder. Because the nominal stroke is 135 mm, the 50 mm adjustment provides a massive 38 percent travel window reduction, which is excellent for dialing in exact positioning.
To replace this cylinder on an ISO 15552 interface, match the 200 mm bore, 135 mm stroke, 50 mm adjustment, PT ports, and the -S magnet. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is under 300 mm, side-load concerns are minimal, though the heavy 40 mm rod and M36x2 thread handle substantial loads. The operating speed range is 30-500 mm/s.
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 SAIJ200AX135-50S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers 3204 kgf.
The rear adjuster screw allows you to trim the 135 mm nominal stroke back by up to 50 mm, creating a usable travel window of 85-135 mm. This mechanical stop fine-tunes the end position but does not lock or hold the load without live air pressure.
