About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-75S
The AirTAC SAIJ200X190-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 115 to 190 mm usable travel window from its 190 mm nominal stroke. Equipped with a SUS420J2 stainless steel rod and a -S magnet for CMSE or DMSE sensors, it provides 15708 N of push force and 15080 N of pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This 200 mm bore pneumatic actuator operates at 30-500 mm/s and uses G3/4 PT tapered ports. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning. It does not lock the load; use a SAIL or BSAI cylinder for fail-safe load holding without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-75S Is Used
Large Fixture Changeover
Dial in the exact retract distance up to 75 mm when switching between heavy product variants on the same machining line.
Heavy Press End-Tuning
Fine-tune the 200 mm bore clamping end-position at commissioning without adding external mechanical stops to the press frame.
Variable Positioning Stops
Adjust the 115-190 mm travel window on the fly to accommodate varying material thicknesses in automated assembly processes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-75S the Right Cylinder?
Choose this 200 mm bore model when your application requires up to 15708 N of thrust at 0.5 MPa and significant end-position flexibility. The 75 mm adjustment range is ideal for product changeovers on large fixtures, allowing you to dial back the stroke by up to 75 mm without swapping hardware. If you need less force, stepping down to a 160 mm bore yields 10053 N push force at 0.5 MPa, which may better suit lighter conveyance tasks.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 190 mm stroke, 75 mm adjuster, G3/4 PT ports, and SUS420J2 (A) rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Since the 190 mm stroke is under the 300 mm side-load threshold, standard guide rails are sufficient, but always ensure the M36x2 rod thread is properly aligned to prevent binding.
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 SAIJ200AX190-75S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you mechanically shorten the 190 mm nominal stroke by up to 75 mm, creating a 115 to 190 mm usable travel window. The adjuster functions only as a travel stop and does not hold the load without continuous air pressure.
