About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-75S
The AirTAC SAIJ200X140-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a substantial 15708N push force at 0.5MPa and uses a SUS304 stainless steel rod with PT tapered ports. The built-in magnet supports CMSE reed and DMSE electronic sensors for exact position detection.
With a 140mm nominal stroke and a 75mm adjustment range, this model yields a highly flexible 65-140mm usable travel window. This allows operators to dial in the exact end-stop during commissioning without adding external stops. The adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-75S Is Used
Heavy Press Fine-Tuning
Dial in the exact 65-140mm travel window during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Size Changeovers
Quickly adjust the retract stop for different package sizes moving down a conveyor line, utilizing the 75mm adjustment range for rapid setup.
Variable End-Stop Positioning
Set precise machine tool endpoints on the fly, using the rear stopper screw to modify the effective stroke without adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-75S the Right Cylinder?
Choose this 200mm bore when you need to step up from a 160mm bore, which provides 10053N of push force at 0.5MPa. The 75mm adjustment range is ideal for product changeovers on a line, allowing rapid variable end-stop modifications instead of swapping out a fixed-stroke SAI cylinder. If true load-holding is required without live air, consider the SAIL lock or BSAI clamp-lock series instead of relying on this adjuster.
For a precise ISO 15552 replacement match, verify the 200mm bore, 140mm stroke, 75mm adjustment, PT port thread, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Although the stroke is 140mm, the heavy 40mm rod and M36x2 thread handle high side loads, but an external guide is recommended for maximum stability.
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 SAIJ200BX140-75S FAQ
At an operating pressure of 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 140mm nominal stroke by up to 75mm, creating a usable travel window of 65-140mm. This stopper sets the travel end and decelerates the load, but it does not lock or hold the load without continuous air pressure.
