About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-30S
The AirTAC SAIJ160X210-30-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 180 to 210 mm, allowing you to dial in the exact end position during commissioning without adding external stops. Belonging to a heavy-duty bore class, it delivers 14074 N of push force at 0.7 MPa.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a -S magnet for electronic position sensing. It uses PT tapered port threads and relies on variable air cushions at both ends to decelerate the load. The rear adjuster acts only as a travel stop, so it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-30S Is Used
Machine Setup & Changeover
Fine-tune the 180-210 mm retract end-stop during machine setup to accommodate new product dimensions without replacing the cylinder.
Heavy Forming End-Positioning
Dial in the exact retracted position for a 14074 N press operation, ensuring precise alignment before applying full clamping force.
Variable End-Stop Assembly
Adjust the travel window on the fly for multi-model assembly lines that require slightly different retract distances on the same station.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-30S the Right Cylinder?
Select this 160 mm bore when an application requires substantial thrust—stepping up from a 125 mm bore gives you 8590 N push at 0.5 MPa, while dropping down to a 200 mm bore yields 21991 N at 0.7 MPa. The adjustable 30 mm travel window is ideal for product changeovers on a line, letting you fine-tune the retract end-position rather than fabricating custom spacers or swapping a fixed-stroke SAI cylinder.
Because the 210 mm stroke exceeds 300 mm? No, but even at 210 mm, the 40 mm rod diameter and M36x2 thread handle considerable side load, though an external guide rail is still recommended for heavy off-center loads. For load-holding without live pressure, this plain SAIJ cylinder is not a lock; you would need an external rod lock or a related type like the BSAI clamp-lock or SAIL. To match this ISO 15552 interchangeable profile exactly: specify 160 mm bore, 210 mm stroke, 30 mm adjustment, 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 SAIJ160 Adjustable Cylinder SAIJ160BX210-30S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can deliver a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 210 mm nominal stroke by up to 30 mm, creating a usable travel window of 180 to 210 mm. The adjuster acts as a mechanical stop to set the end position and does not function as a lock to hold the load without live air.
