About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-40S
The AirTAC SAIJ200X950-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a nominal 950 mm stroke and a 40 mm adjustment range, it provides a usable travel window of 910 to 950 mm. This eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers.
Designed for heavy loads, the 200 mm bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, reaching a maximum of 3204 kgf at 1.0 MPa. This variant includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a -S magnet for position sensing. It operates at 30-500 mm/s and uses PT tapered G3/4 ports.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-40S Is Used
Heavy Press Tuning
Dial in the exact 910-950 mm travel window during heavy press commissioning to accommodate material thickness variations without changing the cylinder.
Product Changeovers
Quickly adjust the end-stop position on a conveyor sorting line when switching to different package sizes, saving setup time over fixed-stroke alternatives.
Large Assembly Stops
Set precise retraction limits for large automotive assembly fixtures where the 15708 N push force and a 950 mm travel distance are required.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-40S the Right Cylinder?
Choose this 200 mm bore adjustable-stroke cylinder when your application requires heavy thrust forces up to 15708 N at 0.5 MPa and precise end-position tuning without mechanical modifications. If you need less force, stepping down to a 160 mm bore drops the push force to 10053 N at 0.5 MPa. The rear adjuster screw acts purely as a travel stop to set the deceleration point; it is not a lock. If your application requires load-holding without live air pressure, use an AirTAC SAIL or BSAI cylinder instead.
This SAIJ200X950-40-S is dimensionally interchangeable per ISO 15552 and includes a -S magnet for CMSE reed and DMSE electronic sensors. It supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. Because the stroke is 950 mm, the 40 mm diameter rod and M36x2 thread still require an external guide to prevent excessive side-loading on the long unsupported travel.

- ✓ 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 SAIJ200AX950-40S 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 its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of thrust.
The rear adjuster screw lets you shorten the 950 mm nominal stroke by up to 40 mm, creating a usable travel window of 910 to 950 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
