About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-50S
The AirTAC SAIJ200X100-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it suited for heavy-duty operations. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This specific SKU features a 100mm nominal stroke paired with a 50mm adjustment range, creating a 50-100mm usable travel window for exact end-position tuning. It incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable stopper allows you to trim the retract distance without adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-50S Is Used
Heavy Press Tuning
Fine-tune the 50-100mm travel window during heavy press setup to accommodate varying material thicknesses without changing the cylinder.
Product Diversion
Adjust the retract end-stop on the fly for different package sizes moving along a high-thrust conveyor line.
Machine Changeover
Rapidly reconfigure end positions during production line changeovers, leveraging the 50mm adjustment screw to skip external stop hardware.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-50S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when an application demands up to 15708N of push force at 0.5 MPa; stepping down to a 160mm bore would reduce that output to 10053N. The 50mm adjustment range is highly valuable for product changeovers, allowing operators to dial in the 50-100mm travel window directly at commissioning rather than swapping out a fixed-stroke SAI cylinder. Because the stroke is 100mm, side-load risks are moderate, but always ensure proper external guiding for the massive 40mm rod.
When replacing an ISO 15552 cylinder, match the 200mm bore, 100mm stroke, 50mm adjustment, PT G3/4 port, and the -S magnet requirement. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for pneumatic load-holding, consider the SAIL or BSAI series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ200AX100-50S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this 100mm nominal stroke model, the -50 code allows you to trim the travel back by up to 50mm, creating a 50-100mm usable window. It is a stop, not a lock, and requires live air to hold position.
