About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-100S
The AirTAC SAIJ200X100-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 100 mm stroke and a 100 mm adjustment range, it provides a highly flexible 0-100 mm usable travel window. This massive bore delivers 15708 N of push force at 0.5 MPa and reaches up to 3204 kgf at 1.0 MPa, making it ideal for heavy-duty pressing. The -S variant includes a magnet for position sensing.
This unit is configured with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-100S Is Used
Heavy-Duty Pressing
Delivers up to 3204 kgf of pressing force with a tunable 0-100 mm travel window, perfect for accommodating different material thicknesses on the same press line.
Product Changeover
Quickly dial back the stroke during line changeovers to accommodate new part sizes without physically swapping out the entire actuator.
Assembly End-Stops
Provides robust end-position tuning for heavy assembly stations, ensuring precise seating of large components without needing external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-100S the Right Cylinder?
Choose this 200 mm bore cylinder when your application demands up to 15708 N of thrust at 0.5 MPa within a variable 0-100 mm travel window. If you need less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The adjustable stroke is perfect for machine commissioning and product changeovers, allowing you to fine-tune the end position without swapping cylinders or adding external stops. For load-holding without continuous air pressure, use an external rod lock, pilot-operated check valve, or select the AirTAC SAIL or BSAI clamp-lock series instead.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 100 mm nominal stroke, 100 mm adjustment range, PT port thread, and -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the 100 mm stroke is relatively short for this large bore, the 40 mm rod diameter and M36x2 thread handle high side loads well, though external guidance is always recommended for heavy payloads.
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 SAIJ200AX100-100S FAQ
At 0.5 MPa operating pressure, it provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 28274 N (3204 kgf).
The rear adjusting screw allows you to shorten the effective stroke by up to 100 mm. Since the nominal stroke is 100 mm, the usable travel window is 0-100 mm. The adjuster is a mechanical stop, not a lock, so the cylinder requires live air to maintain position.
