About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-50S
The AirTAC SAIJ200X1000-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position without adding external stops. It provides a usable travel window of 950-1000 mm, trimming the 1000 mm nominal stroke by up to 50 mm during commissioning or product changeovers. Built to generate 15708 N of push force and 15080 N of pull force at 0.5 MPa, it handles heavy industrial loads with precision.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston for position feedback. The extruded aluminum barrel features sensor grooves on both sides, directly accepting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid ports are PT tapered thread (G3/8), and the unit relies on variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-50S Is Used
Heavy Press Tuning
Dial in the exact 950-1000 mm end-stop during heavy press commissioning to accommodate material thickness variations without external stopper hardware.
Pallet Positioning
Adjust the retract position on the fly during product size changeovers on a conveyor line, ensuring precise pallet alignment without swapping out the cylinder.
Large Assembly Jigs
Utilize the 15708 N thrust and SUS304 rod in large-scale assembly jigs where the final end-of-stroke position must be tweaked for different fixture heights.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-50S the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires the maximum 15708 N push force at 0.5 MPa (or up to 3204 kgf at 1.0 MPa) and on-the-fly end-position tuning. If you need less force, stepping down to the 160 mm bore yields 10053 N of push at 0.5 MPa, whereas the 200 mm bore is necessary for heavy pressing or lifting. Because the stroke is 1000 mm, you must account for side-loading; the 40 mm rod diameter and M36x2 thread provide robust support, but an external guide is strongly recommended for such a long unsupported travel to prevent premature seal wear.
Choose the adjustable SAIJ over a fixed SAI when your machine setup demands a variable end-stop without swapping cylinders. The rear adjuster acts purely as a mechanical travel stop, not a lock; a plain SAIJ does not hold its load without live air pressure. For load-holding requirements without continuous pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. This model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAIJ200BX1000-50S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the 1000 mm nominal stroke by up to 50 mm, providing a usable 950-1000 mm travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
