About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-40S
The AirTAC SAIJ200X150-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 150 mm nominal stroke that can be fine-tuned down by up to 40 mm, yielding a usable travel window of 110-150 mm. Delivering a substantial 15708 N of push force at 0.5 MPa, this bore size is built for heavy-duty positioning tasks.
This configuration features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and fluid control is managed through G3/4 PT tapered ports.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-40S Is Used
Heavy Press Tuning
Dial in the exact 110-150 mm end-of-stroke position on heavy pressing operations without swapping cylinders or adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper by up to 40 mm to accommodate new product sizes on a high-force assembly line during format changeovers.
Robotic End Effectors
Utilize the 15708 N thrust and SUS304 rod for robust, corrosion-resistant actuation in demanding industrial automation cells.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-40S the Right Cylinder?
Select this 200 mm bore actuator when an application demands high thrust, such as the 14074 N push force available at 0.7 MPa, alongside precise end-position tuning without external stops. If the load requires less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The rear adjuster screw acts strictly as a travel stop to dial in the 110-150 mm window during commissioning; it does not hold the load without live air. For position holding without pneumatic pressure, consider an AirTAC SAIL or BSAI series cylinder.
Because this is a 150 mm stroke unit, the 40 mm diameter rod handles side loads well, though any long unsupported loads should still use an external guide. As a dimensionally interchangeable ISO 15552 profile cylinder, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Ensure your setup matches the G3/4 PT ports and the 30-500 mm/s speed range.
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 SAIJ200BX150-40S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw allows you to shorten the 150 mm nominal stroke by up to 40 mm, creating a usable travel window of 110-150 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
