About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX110-40S
The AirTAC SAIJ200X110-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 110 mm nominal stroke that can be dialed back by up to 40 mm, creating a precise 70-110 mm usable travel window for commissioning without external stops. As the largest bore in the SAIJ range, it delivers massive thrust up to 15708 N at 0.5 MPa, making it ideal for heavy-duty positioning tasks.
This specific SKU is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. It uses PT tapered ports sized at G3/4 and relies on variable air cushions at both ends to decelerate heavy loads. Remember that the rear adjuster is a travel stop, not a locking device; it will not hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX110-40S Is Used
Heavy Press Fine-Tuning
Dial in the exact 70-110 mm end-of-stroke position during heavy press setup, allowing precise material forming without swapping physical cylinder stops.
Automated Assembly Changeover
Quickly adjust the travel window for different product sizes on a high-force automated assembly line, minimizing downtime between production runs.
Variable Metal Forming
Accommodate varying material thicknesses in a bending or straightening station by trimming the retract stroke up to 40 mm on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX110-40S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires up to 15708 N of push force at 0.5 MPa, or 21991 N at 0.7 MPa. If your force requirements are lower, stepping down to a 160 mm bore provides 10053 N at 0.5 MPa, which may offer a more compact and efficient solution. The adjustable 70-110 mm travel window is highly beneficial for product changeovers or fine-tuning end positions on the fly, preventing the need to physically swap out a fixed-stroke SAI cylinder.
When ordering, confirm the ISO 15552 replacement attributes: 200 mm bore, 110 mm nominal stroke, 40 mm adjustment range, PT G3/4 ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets. For applications requiring the cylinder to hold its position safely without live air, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead. Because the stroke is 110 mm, side-load risks are minimal, but always guide heavy loads appropriately.
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 SAIJ200BX110-40S 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 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw allows you to shorten the 110 mm nominal stroke by up to 40 mm, providing a usable travel window between 70 mm and 110 mm. This stopper only sets the end position and does not lock the load without live air.
