About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-40
The AirTAC SAIJ160X210-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 210 mm nominal travel by up to 40 mm. This creates a precise 170-210 mm usable window, enabling fine end-position tuning at commissioning without swapping the barrel or adding external mechanical stops. Built with a SUS304 stainless steel rod (option B) and PT tapered ports, it delivers robust thrust of 14074 N at 0.7 MPa.
The rear adjuster acts purely as a travel stop and works alongside the 50 mm variable air cushions at both ends to decelerate the load; it is not a lock and will not hold a load without live air pressure. The extruded aluminum barrel features sensor grooves on both sides for CMSE and DMSE switches, though this specific SKU ships without a magnet. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-40 Is Used
Heavy Product Changeover
Dial in the 170-210 mm travel window during format changes on heavy assembly lines without removing the cylinder or adding external shims.
Press End-Position Tuning
Fine-tune the final retract position during machine commissioning to achieve exact clamping or pressing forces on large components.
Adjustable Ejection Force
Modify the ejection stroke length on the fly to safely eject parts of varying widths without reconfiguring the entire pneumatic setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-40 the Right Cylinder?
Choose this 160 mm bore when your application requires significantly more force than the 125 mm class (8590 N at 0.7 MPa) but less than the massive 200 mm bore (21991 N at 0.7 MPa). The 40 mm adjustable stroke is ideal for product-size changeovers on a line, letting you set a new retract end-stop on the fly instead of machining custom spacers. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster only sets the travel end. If you need an ISO 15552 replacement, match the 160 mm bore, 210 mm stroke, 40 mm adjustment, PT ports, SUS304 rod, and your required mounting interface. At 210 mm of travel, ensure external guides support the load to prevent excessive side-loading on the 40 mm rod.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ160BX210-40 FAQ
The 160 mm bore generates 10053 N of push force and 9425 N of pull force at 0.5 MPa. At 0.7 MPa, it provides 14074 N of push force.
The rear adjuster screw lets you shorten the 210 mm nominal stroke by up to 40 mm, creating a 170-210 mm usable travel window. It functions as a mechanical stop for end-position tuning and does not hold the load without air pressure.
