About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX240-40S
The AirTAC SAIJ200X240-40-S is a double-acting ISO 15552 profile cylinder engineered for high-force applications requiring precise end-position tuning. Equipped with a rear mechanical stopper, it allows you to dial back the 240 mm nominal stroke by up to 40 mm, creating a 200-240 mm adjustable travel window. This means you can perfect the retract position at commissioning without swapping out the cylinder or adding external stops. Delivering a massive 15708 N of push force at 0.5 MPa, it handles the heaviest pneumatic tasks.
This SKU ships with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet (-S) for seamless position sensing with AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting. Fluid speed operates between 30-500 mm/s, and the G3/4 PT tapered ports ensure high flow capacity for rapid actuation.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX240-40S Is Used
Heavy Press Tuning
Fine-tune the exact end-of-stroke position on heavy stamping or press equipment during setup, adjusting the travel window by up to 40 mm without replacing the cylinder.
Product Size Changeovers
Accommodate varying product dimensions on a high-force production line by quickly dialing the retract stroke between 200 and 240 mm for different tooling heights.
Heavy Material Handling
Position large metal or composite components with precision, leveraging the 15708 N push force and SUS304 rod for durable, corrosion-resistant operation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX240-40S the Right Cylinder?
Choose this 200 mm bore when 160 mm falls short, as stepping down to a 160 mm cylinder drops your 0.5 MPa push force to 10053 N. The adjustable stroke is ideal for product changeovers on large machinery, letting you fine-tune the retract distance on the fly instead of machining new hard stops. Because the 240 mm stroke exceeds 300 mm? Actually, at 240 mm it is under the 300 mm threshold, but with a heavy 40 mm adjustment, you must still ensure the 40 mm rod diameter and M36x2 thread can handle any induced side loads—use an external guide for heavy payloads. For load-holding without live air pressure, note that the rear adjuster acts only as a travel stop, not a lock; you would need an external rod lock or a SAIL/BSAI series cylinder. To replace an ISO 15552 cylinder, match the 200 mm bore, 240 mm stroke, 40 mm adjust, G3/4 PT ports, and the -S magnet.

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 SAIJ200BX240-40S FAQ
At a 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 acts as a mechanical stop that lets you shorten the 240 mm nominal stroke by up to 40 mm. This provides a usable travel window of 200-240 mm, allowing precise end-position tuning at commissioning without external stops.
