About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20S
The AirTAC SAIJ32X800-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel within a 780-800 mm window. Delivering 402 N of push force at 0.5 MPa, it utilizes a 12 mm SUS304 stainless steel rod and PT tapered port threads. The integrated -S magnet enables precise position detection with AirTAC CMSE reed and DMSE electronic sensors.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during commissioning or product changeover. The rear screw acts purely as a mechanical travel stop and does not hold the load without live air pressure. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20S Is Used
End-Stop Tuning
Dial in the exact 780-800 mm retract position during machine commissioning without physically swapping out long-stroke cylinders.
Product Changeover
Quickly adapt automated lines to new part sizes by adjusting the rear stopper screw to meet new dimensional requirements.
Long-Travel Sorting
Provides reliable 402 N push force across an 800 mm stroke for diverting or positioning items on extended conveyor sections.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20S the Right Cylinder?
Choose this 32 mm bore when you need variable end-position tuning within an 800 mm travel window. If your application requires higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 800 mm stroke is long and the 12 mm rod is relatively slender, an external guide is highly recommended to prevent excessive side-load wear on the barrel seals.
For load-holding without continuous live air pressure, this cylinder is insufficient because the rear adjuster and air cushions only decelerate the travel end. You must pair it with an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAI clamp-lock cylinder. To match this ISO 15552 interchangeable unit, specify: 32 mm bore, 800 mm stroke, 20 mm adjustment, PT ports, SUS304 rod, 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 Adjustable Cylinder SAIJ32 SAIJ32BX800-20S FAQ
The rear adjuster screw lets you shorten the nominal 800 mm stroke by up to 20 mm, giving a usable travel window of 780-800 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 80 kgf.
