About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX130-20
The AirTAC SAIJ200X130-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to trim the effective travel to a precise 110-130 mm window during commissioning. Built with a SUS304 stainless steel rod and PT tapered ports, it generates a substantial 15708 N of push force at 0.5 MPa, scaling up to 21991 N at 0.7 MPa for heavy-duty positioning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning end positions. The rear screw acts purely as a travel stop and works alongside the standard air cushions to decelerate the load, but it does not hold the load without live air pressure. For secure load-holding, an external rod lock or a related SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX130-20 Is Used
Heavy Press Tuning
Dial in the exact 110-130 mm pressing depth during commissioning to accommodate different material thicknesses without changing the tooling.
Product Changeovers
Adjust the rear stopper on the fly for varying product sizes on a high-force assembly line, minimizing downtime between production runs.
Large Assembly Positioning
Fine-tune the retraction end-point of heavy components during automated alignment, ensuring precise mating without external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX130-20 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires massive thrust—such as 15708 N at 0.5 MPa—and on-the-fly end-position tuning. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may simplify your air consumption. The SAIJ200X130-20 is chosen over a fixed-stroke SAI when machine setups involve frequent product-size changeovers that demand a variable end-stop rather than a rigid, fixed travel distance.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 130 mm stroke, 20 mm adjustment range, PT port threads, and your required mounting style. The SAIJ series supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Since this is a non-magnet variant, position sensing is not supported without adding a magnet (-S) for CMSE reed or DMSE electronic switches.

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 SAIJ200BX130-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
The rear adjuster screw allows you to shorten the 130 mm nominal stroke by up to 20 mm, creating a usable travel window of 110 to 130 mm. This stopper only sets the travel end and does not lock the load without continuous air pressure.
