About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX400-75
The AirTAC SAIJ200X400-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 400 mm stroke back by up to 75 mm, creating a precise 325-400 mm usable travel window. Built with an extruded aluminum barrel, it delivers massive thrust up to 21991 N at 0.7 MPa, making it suited for heavy-duty pressing. It uses a SUS304 stainless steel rod for superior corrosion resistance and features a G3/4 port for high-volume airflow.
This model omits the FB, CA, CB, and CR mounting options, utilizing a reduced ISO 15552 mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) to simplify design integration. The rear stopper acts purely as a travel end-deceleration point, not a lock, meaning it cannot hold a load without live air pressure. For secure load-holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX400-75 Is Used
Heavy Press Tuning
Dial in the exact 325-400 mm end-of-stroke position for heavy pressing tasks without needing to physically swap out a massive 200 mm bore cylinder.
Product Changeover
Adjust the rear stopper during machine changeover to accommodate different product sizes quickly and safely within the 75 mm window.
Industrial Automation
Integrate this high-force ISO 15552 profile cylinder into large-scale automated lines where a 21991 N push output and robust SUS304 rod are required.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX400-75 the Right Cylinder?
When specifying this 200 mm bore cylinder, which delivers 21991 N of push force at 0.7 MPa, stepping down to a 160 mm bore yields 14074 N at the same pressure, making this model necessary only for the most demanding high-force applications. The 75 mm adjustable window is ideal for fine-tuning the end position during commissioning or product changeover without swapping the cylinder or adding external stops. Because the nominal stroke is 400 mm, the 40 mm diameter rod and M36x2 thread provide substantial rigidity, but an external guide is still recommended to manage side loads over this long travel distance. This configuration uses PT tapered ports and lacks a magnet (-S), meaning direct position sensing via CMSE or DMSE switches is not supported out of the box.
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 SAIJ200BX400-75 FAQ
At an operating pressure of 0.7 MPa, this 200 mm bore double-acting cylinder provides a push force of 21991 N and a pull force of 15080 N.
The rear adjuster acts as an external stop that lets you shorten the effective stroke from its nominal 400 mm down to as little as 325 mm, providing a 75 mm tuning window for precise end-positioning without replacing the cylinder.
