Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 210mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100S
The AirTAC SAIJ160X210-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 160 mm bore and a 210 mm nominal stroke that can be dialed back by up to 100 mm, yielding a highly flexible 110-210 mm usable travel window for precise end-position tuning during commissioning. In the push direction at 0.5 MPa, it generates 10053 N of thrust, placing it firmly in the heavy-duty class.
This specific configuration incorporates a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports position detection via AirTAC CMSE reed switches or DMSE solid-state electronic sensors. The rear adjustment mechanism acts purely as a travel stop to set the retract end, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100S Is Used
Variable End-Stop Setup
Dial in the exact retract position within the 110-210 mm window during machine commissioning without swapping out the physical cylinder.
Product Size Changeover
Quickly adapt a packaging or pressing line to different material thicknesses by adjusting the rear stopper up to 100 mm on the fly.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for heavy-duty pressing tasks in washdown or chemically exposed facilities requiring reliable sensing.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100S the Right Cylinder?
Select this 160 mm bore model when an application requires substantial force—such as the 10053 N push thrust at 0.5 MPa—coupled with the ability to fine-tune the travel distance on the fly. If your process demands less than 9425 N pull force at 0.5 MPa, stepping down to a 125 mm bore is advised, whereas higher force requirements up to 15708 N push at 0.5 MPa would necessitate the 200 mm bore. The 100 mm adjustment range here is ideal for product-size changeovers on a line, eliminating the need to physically swap cylinders or bolt on external stops as you would with a fixed-stroke SAI model.
Because the nominal stroke of 210 mm is relatively short, side-load risks are minimized, though the robust 40 mm rod and M36x2 thread handle substantial loads well. For applications requiring the cylinder to maintain its position or hold a load without continuous air pressure, note that this plain SAIJ adjuster is not a lock; you should instead explore AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinders. To match this ISO 15552 interchangeable unit, specify: 160 mm bore, 210 mm stroke, 100 mm adjustment, PT G3/4 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX210-100S FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push thrust and 9425 N of pull thrust. At the maximum 1.0 MPa pressure, the push force reaches 18095 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 210 mm nominal stroke down to 110 mm. It only sets the end position and decelerates the stroke; it does not lock or hold the load without live air pressure.
