About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-50
The AirTAC SAIJ200X140-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 140 mm travel by up to 50 mm. This creates a precise 90 to 140 mm usable window for fine-tuning the retract end position during commissioning without adding external stops. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
Built for demanding environments, this configuration features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides. While the rear adjuster and dual air cushions safely decelerate the load, neither acts as a lock; for load-holding without live air pressure, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-50 Is Used
Heavy Press Tuning
Dial in the exact 90 to 140 mm retract position during heavy press setup to accommodate different material thicknesses without changing the fixture.
Product Changeover
Adjust the end stop on the fly when switching package sizes on a high-thrust conveyor diverter, saving downtime on the production line.
Large Assembly Jigs
Provide a variable end-position stop for large-scale assembly jigs where the 15708 N push force is needed to seat heavy components accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-50 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires the 15708 N push force at 0.5 MPa that a smaller 160 mm bore (providing 10053 N) cannot achieve. The adjustable stroke is ideal for product-size changeovers on a line, letting operators reset the end-of-travel position quickly instead of swapping the entire cylinder. Because the total travel reaches up to 140 mm, ensure your external guide mechanism handles any potential side loads, as the large 40 mm rod thread handles high stress but cannot eliminate deflection entirely.
When matching this cylinder for an ISO 15552 replacement, verify the 200 mm bore, 140 mm stroke, 50 mm adjustment range, PT port thread, and the absence of a magnet (non-S). It uses the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ200BX140-50 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it achieves a push force of 28274 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 140 mm nominal stroke by up to 50 mm, providing a usable travel window of 90 to 140 mm. It only sets the end position and does not lock the load without live air pressure.
