About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-10S
The AirTAC SAIJ200X140-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust with a 15708N push force at 0.5 MPa. It features a 140mm nominal stroke that can be dialed back by up to 10mm, creating a precise 130-140mm usable travel window for exact end-position tuning during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and this specific SKU is configured with a SUS304 stainless steel rod and a magnetic piston for position detection.
Because the rear screw acts purely as a mechanical stop to set the travel end, it does not hold the load without live air pressure; for load-holding requirements, consider the SAIL or BSAI variants. This 200mm bore model uses G3/4 PT ports and supports a speed range of 30-500mm/s. It utilizes the standard SAIJ mounting subset, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR mounts.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-10S Is Used
Heavy Press Tuning
Dial in the exact 130-140mm clamping end-position on high-force metal forming presses without changing the cylinder.
Product Changeover
Quickly adjust the retract stop during automated line changeovers to accommodate different large-scale product dimensions.
Assembly Actuation
Provides the massive 15708N push force needed to seat heavy industrial components, with a 10mm trim for perfect mating.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-10S the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme force, such as 15708N push at 0.5 MPa, alongside precise 130-140mm travel adjustability. If you need slightly less thrust, stepping down to a 160mm bore yields 10053N of push force at 0.5 MPa, but the 200mm bore with its robust 40mm rod and M36x2 thread provides superior side-load resistance. An adjustable stroke is highly beneficial for machine setups requiring product-size changeovers, allowing you to fine-tune the retract position without swapping cylinders or adding external stops. For load-holding without continuous air supply, you must integrate an external rod lock or pilot-operated check valve, as the SAIJ adjuster is not a brake.
When matching this for an ISO 15552 replacement, verify the 200mm bore, 140mm stroke, 10mm adjustment range, G3/4 PT ports, and the -S magnet requirement. The included magnetic piston works seamlessly with AirTAC CMSE reed switches and DMSE electronic solid-state sensors. Although the 140mm stroke is below the 300mm side-load warning threshold, the heavy 40mm rod diameter still necessitates proper external guiding for heavy loads.
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 SAIJ200BX140-10S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 28274N.
The rear adjuster screw allows you to shorten the 140mm nominal stroke by up to 10mm, providing a usable travel window of 130-140mm. This mechanical stop fine-tunes the end position but does not lock the load without live air pressure.
