About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX350-40S
The AirTAC SAIJ200X350-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 310 to 350 mm. Belonging to the 200 mm bore class, it outputs 15708 N of push force and 15080 N of pull force at 0.5 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Because the stroke is 350 mm, the 40 mm diameter rod and M36x2 thread provide substantial rigidity, though an external guide is recommended to manage side loads on long travels.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX350-40S Is Used
Heavy Press Tuning
Fine-tune the exact bottoming position of a 15080 N pressing operation within a 310-350 mm window without swapping out the entire actuator.
Product Changeover
Quickly adjust the rear stopper by up to 40 mm on a packaging line when transitioning to a different pallet or product size.
Large Assembly Jigs
Leverage the SUS304 stainless steel rod and robust M36x2 thread in harsh environments to position heavy assemblies accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX350-40S the Right Cylinder?
Choose this 200 mm bore actuator when an application requires immense thrust, such as 15708 N at 0.5 MPa, combined with on-the-fly end-position tuning. If your setup only needs 10053 N of push force, stepping down to the 160 mm bore saves space and air consumption. Conversely, if you need to trim weight or cycle faster at lower forces, the 125 mm bore offers 6136 N. The adjustable rear stopper allows you to dial in the exact 310-350 mm stroke during commissioning without adding external physical stops.
For ISO 15552 replacement matching, specify the 200 mm bore, 350 mm nominal stroke, 40 mm adjustment, PT port thread, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets.

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 SAIJ200BX350-40S 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 the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 310 to 350 mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
