About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-100S
The AirTAC SAIJ200X145-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a robust 200 mm bore generating 15708 N of push force at 0.5 MPa, alongside a SUS304 stainless steel rod for superior corrosion resistance. By turning the rear screw, you achieve a usable travel window of 45-145 mm, allowing precise end-position tuning without swapping hardware.
This model includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the dual-side extruded aluminum barrel grooves. It uses a G3/4 PT port and omits the FB, CA, CB, and CR mounting options, supporting only the Basic, FA, LB, TC, FTC, TCM1, and TCM2 ISO 15552 interface set.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-100S Is Used
Heavy Press Tuning
Dial in the exact 45-145 mm end-stop during heavy press commissioning to prevent over-travel without machining new hard stops.
Product Size Changeover
Rapidly adapt a high-force line to varying product lengths by adjusting the rear screw up to 100 mm between production runs.
Corrosive High-Force Clamping
Leverage the 15708 N thrust and SUS304 stainless steel rod to securely clamp large workpieces in humid or wash-down environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-100S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme thrust—up to 15708 N at 0.5 MPa—combined with variable end-stops for rapid product changeovers. If your process requires less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, whereas moving up is impossible as 200 mm is the largest standard size. The wide 100 mm adjustment window is perfect for prototyping or accommodating multiple product sizes on a single line.
Because the 145 mm stroke is well under the 300 mm side-load threshold, the hefty 40 mm rod handles typical loads easily, though external guides remain best practice for heavy lifting. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for dead-air locking, consider an AirTAC SAIL or BSAI cylinder. This SKU is dimensionally interchangeable per ISO 15552, requiring a 200 mm bore, 145 mm stroke, 100 mm adjust, G3/4 PT port, and -S magnet for a direct replacement.

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 SAIJ200BX145-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 28274 N at 1.0 MPa.
The rear adjuster screw allows you to trim the effective travel back by up to 100 mm from the 145 mm nominal stroke, creating a usable window of 45-145 mm. It functions as a hard stop for end-position tuning and does not lock the load without continuous air pressure.
