About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-30
The AirTAC SAIJ200X230-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It features a 200 mm bore and a 230 mm nominal stroke that can be dialed back by up to 30 mm, creating a precise 200-230 mm usable travel window for exact end-position tuning. With a push force of 21991 N at 0.7 MPa, it handles substantial loads effortlessly.
This variant utilizes an SUS420J2 stainless steel rod for enhanced durability against moisture and PT tapered port threads for a robust pneumatic connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing for flexible mounting of CMSE or DMSE switches if a magnet is added later. The rear adjusting screw acts purely as a mechanical stop to set the retraction endpoint, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-30 Is Used
Heavy Press Tuning
Dial in the exact 200-230 mm end position during machine commissioning to accommodate different material thicknesses without adding external mechanical stops.
Product Changeover
Quickly adjust the retraction point on automated assembly lines when switching between large product sizes, minimizing downtime.
High-Force Positioning
Leverage the 21991 N push force at 0.7 MPa to move heavy payloads while fine-tuning the stroke limit to prevent over-travel damage.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-30 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires up to 3204 kgf of maximum force, stepping up significantly from a 160 mm bore that provides 14074 N at 0.7 MPa. The adjustable 200-230 mm travel window is ideal for applications needing variable end stops or fine-tuning during product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. To match this exact configuration for an ISO 15552 replacement, specify the 200 mm bore, 230 mm stroke, 30 mm adjustment, PT ports, and SUS420J2 rod material.
Because the 230 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread provide excellent rigidity, but an external guide is still recommended to prevent excessive side-loading on long extensions. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not function as a brake. For applications requiring true load-holding without continuous air pressure, consider the SAIL or BSAI series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200AX230-30 FAQ
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 30 mm, providing a usable travel window of 200 to 230 mm. It acts as a physical stop for the retract end position and must be set during commissioning.
At an operating pressure of 0.7 MPa, the SAIJ200X230-30 provides a push force of 21991 N and a pull force of 15080 N. At the maximum rated pressure of 1.0 MPa, it can deliver a peak push force of 15708 N.
