About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-100
The AirTAC SAIJ200X100-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust with 15708N push and 15080N pull at 0.5 MPa. It features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered ports. Because the nominal 100mm stroke is paired with a 100mm adjustment code, the usable travel window spans 0 to 100mm, effectively turning this unit into a highly versatile variable-stop actuator.
This adjustable-stroke design allows operators to fine-tune end positions directly at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, adding one enables compatibility with AirTAC CMSE reed and DMSE electronic sensors. The rear screw acts purely as a travel stop to set deceleration limits, meaning it cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-100 Is Used
Heavy Press Tuning
Dial in the exact bottoming position of a high-tonnage press on the fly using the 0-100mm travel window to accommodate different material thicknesses.
Product Changeover
Rapidly reconfigure end-stops on a packaging line without disassembling the actuator setup, minimizing downtime between product runs.
Variable Stops
Establish precise deceleration endpoints for heavy machinery loads, using the rear stopper to set the travel limit exactly where the process requires.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-100 the Right Cylinder?
Choose this 200mm bore actuator when an application demands extreme force alongside variable end-stop positioning, stepping up from a 160mm bore that provides 10053N push at 0.5 MPa. The SUS304 rod and M36x2 thread provide excellent structural integrity and side-load resilience, though any stroke approaching or exceeding 300mm would still require an external guide to prevent rod deflection. For load-holding without continuous air pressure, a plain SAIJ is insufficient; you should explore the SAIL air-released lock or BSAI clamp-lock variants instead.
To match this ISO 15552 interchangeable cylinder exactly, specify the 200mm bore, 100mm nominal stroke, 100mm adjustment range, PT port threads, and the SUS304 rod material. Mounting options are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets found on other series.

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 SAIJ200BX100-100 FAQ
At an operating pressure of 0.5 MPa, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum pressure of 1.0 MPa, it achieves a push force of 31416N.
The rear adjusting screw allows you to trim the effective travel back by up to 100mm from the nominal 100mm stroke, creating a 0-100mm usable travel window. The adjuster is a mechanical stop for setting the end position, not a lock, and cannot hold a load without live air.
