About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-30
The AirTAC SAIJ200X100-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering 15708N of push force at 0.5 MPa. By integrating a rear stopper mechanism, this model allows you to trim the nominal 100mm stroke back by up to 30mm. This creates a precise 70-100mm usable travel window, enabling exact end-position tuning during commissioning without the need to physically swap the cylinder or bolt on external stops.
Built for demanding environments, this variant features a highly corrosion-resistant SUS304 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward positioning feedback. While the rear adjuster and dual-end air cushions effectively decelerate the load at the travel end, note that this cylinder relies on live air pressure and does not function as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-30 Is Used
Heavy Pressing Operations
Ideal for applying massive clamping or pressing forces, where the 70-100mm travel window can be fine-tuned to accommodate different material thicknesses on the fly.
Product Changeover Systems
Perfect for automated lines handling varying product sizes, allowing operators to mechanically adjust the end-stop position up to 30mm without swapping out the entire actuator.
Industrial Forming Jigs
Provides reliable, high-force linear movement for large-scale forming and jig operations, utilizing the SUS304 rod to withstand harsh, corrosive shop environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-30 the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application requires substantial thrust, such as the 15708N push force generated at 0.5 MPa. If your setup demands less force, stepping down to a 160mm bore yields 10053N of push force at the same pressure, whereas keeping the 200mm bore ensures maximum pushing capacity up to 3204 kgf at 1.0 MPa. The 30mm adjustable range is specifically advantageous for product-size changeovers on a line, allowing operators to dial in the exact 70-100mm stroke mechanically rather than reprogramming fixed SAI cylinder stops.
As an ISO 15552 interchangeable cylinder, this unit features PT tapered ports and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 100mm stroke is relatively short for this massive bore, side-load risks are minimal, but an external guide remains recommended for heavy lateral loads. For applications requiring true position holding without live air, consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ200 Adjustable Cylinder SAIJ200BX100-30 FAQ
At a 0.5 MPa operating pressure, this 200mm bore cylinder generates 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of thrust.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 100mm stroke by up to 30mm, creating a usable travel window of 70-100mm. This enables precise end-position tuning at commissioning without changing the cylinder itself.
