About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-75S
The AirTAC SAIJ200X190-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suited for heavy-duty positioning. The -75 code provides a 75 mm adjustment range, creating a usable travel window between 115 and 190 mm for exact end-position tuning at commissioning.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered G3/4 ports and relies on a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR. The rear screw acts purely as a mechanical stop to decelerate travel, not as a lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-75S Is Used
Heavy Press Tuning
Dial in the exact 115-190 mm travel window on heavy pressing operations to accommodate varying material thicknesses without repositioning the cylinder.
Machine Changeover
Rapidly adjust the retract end-stop during product size changes on the line, using the 75 mm trim range to hit new positions quickly.
Corrosive Assembly
Leverage the SUS304 rod and 28274N push force to drive heavy assembly tooling in washdown or corrosive factory environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-75S the Right Cylinder?
Select this 200 mm bore when an application demands up to 3204 kgf at 1.0 MPa but requires on-the-fly stroke trimming rather than a fixed 190 mm SAI cylinder. The 75 mm adjustment window lets you dial in the exact retract position during machine setup or product changeover without swapping the cylinder or adding external stops. If you need to step down force, a 160 mm bore offers 18095N at 0.9 MPa.
Because the 190 mm stroke is below the 300 mm threshold, side-load stress is moderate, though the robust 40 mm rod and M36x2 thread handle high loads well. Remember that the rear adjuster and air cushions do not hold the load without live air; for fail-safe load holding, specify an SAIL or BSAI cylinder. For a direct ISO 15552 replacement match: 200 mm bore, 190 mm stroke, 75 mm adjust, PT G3/4 ports, SUS304 rod, and -S magnet.
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 SAIJ200BX190-75S FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder provides a push force of 28274N and a pull force of 15080N. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you mechanically shorten the nominal 190 mm stroke by up to 75 mm, providing a usable travel window of 115 to 190 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
