About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-100S
The AirTAC SAIJ200X375-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an effective travel window of 275 to 375 mm. Built with a SUS304 stainless steel rod and a magnetic piston for use with CMSE reed and DMSE electronic sensors, it delivers massive thrust up to 3204 kgf at 1.0 MPa. A PT tapered port ensures a tight pneumatic seal, while the extruded aluminum barrel integrates sensor grooves on both sides.
This adjustable model uses an external stopper screw at the rear to trim the retract position without swapping hardware. The rear adjuster functions purely as a travel stop and does not hold the load without live air pressure. For applications requiring true load-holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-100S Is Used
Heavy Press Tuning
Dial in the exact 275 to 375 mm retract position during machine setup to accommodate varying material thicknesses without changing out the entire cylinder.
Product Changeover
Quickly adjust the end-stop on automated assembly lines when switching product sizes, leveraging the 100 mm travel window to avoid mechanical rework.
High-Force Positioning
Move heavy structural components with up to 3204 kgf of thrust while relying on the integrated PT port and 50 mm air cushions to manage deceleration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-100S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your machinery requires extreme push force, such as 21991 N at 0.7 MPa, and demands variable end-stops for product changeovers. The 100 mm adjustment window allows operators to dial in the exact retract position during commissioning, avoiding the need to machine custom external stops. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, saving space and air consumption.
Because the 375 mm stroke creates a long unsupported rod extension, an external guide mechanism is recommended to prevent excessive side-loading and premature seal wear. When replacing an ISO 15552 cylinder, match the 200 mm bore, 375 mm nominal stroke, 100 mm adjustment range, PT port thread, and the -S magnet requirement. The dual-side cushioning strokes of 50 mm provide robust end-of-travel deceleration for heavy loads moving at speeds up to 30-500 mm/s.

- ✓ 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 SAIJ200BX375-100S FAQ
At the maximum operating pressure of 1.0 MPa, this 200 mm bore cylinder generates a maximum push force of 3204 kgf. At a standard 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force.
The rear adjuster acts as an external stopper screw, allowing you to shorten the nominal 375 mm stroke by up to 100 mm, creating a usable travel window of 275 to 375 mm. It only sets the travel end and does not lock the load without continuous air pressure.
