About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-100
The AirTAC SAIJ200X140-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down from a 140 mm nominal stroke to a 40-140 mm usable window. Equipped with a robust 40 mm SUS304 stainless steel rod and a G3/4 PT tapered port, it delivers massive thrust, generating 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 mounting of CMSE or DMSE switches.
Because the rear adjuster acts solely as a mechanical stop to set the travel end, it does not hold the load without live air pressure. For true load-holding without continuous air, you would need to step up to an SAIL (air-released lock) or BSAI (clamp-lock) variant. This SAIJ model supports a speed range of 30-500 mm/s and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options entirely.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 40 to 140 mm during machine commissioning, perfect for setups where the exact end position varies by product batch.
Heavy-Duty Pressing
Leverage the 15708 N push force at 0.5 MPa for heavy pressing or forming tasks, adjusting the travel window to accommodate different material thicknesses.
Product Size Changeover
Quickly adapt automated lines to new product dimensions by turning the rear adjuster screw, eliminating the need to physically swap out pneumatic cylinders.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-100 the Right Cylinder?
Choose this 200 mm bore when you need extreme force—stepping down to a 160 mm bore yields 10053 N of push at 0.5 MPa, whereas this 200 mm bore provides 15708 N. The adjustable stroke is highly beneficial for machine setup and product changeover, allowing you to fine-tune the end position at commissioning without swapping out the entire cylinder or adding external stops. When matching this for an ISO 15552 replacement, verify the 140 mm stroke, 100 mm adjustment range, G3/4 PT port, and the specific mounting accessory. Note that the large 40 mm rod thread handles significant side loads, but even with a robust rod, any application approaching longer strokes requires an external guide 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 SAIJ200BX140-100 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 100 mm. This gives the 140 mm nominal stroke a usable travel window of 40-140 mm, allowing fine-tuning of the retract end position without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 15708 N of push force and 15080 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 21991 N.
