About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-20
The AirTAC SAIJ200X130-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 130 mm nominal stroke and a 20 mm adjustment range, it provides a usable travel window of 110-130 mm, allowing precise end-position tuning during commissioning without swapping the cylinder or adding external stops. It delivers a robust 15080 N pull force at 0.5 MPa, making it suited for heavy-duty manipulation.
This model incorporates an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic solid-state sensors. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-20 Is Used
Heavy Machinery Setup
Dial in the 110-130 mm travel window during initial heavy machinery commissioning to perfect the end position without machining external stopper blocks.
Product Size Changeover
Quickly adapt the cylinder's effective stroke on production lines handling varying product sizes, using the rear screw to accommodate different package dimensions.
Press End-Position Tuning
Fine-tune the retraction end-stop on heavy pressing or clamping stations, ensuring precise contact without over-traveling the 200 mm bore mechanism.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-20 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires substantial force, delivering 15080 N of pull force at 0.5 MPa. If your setup demands less thrust, stepping down to a 160 mm bore provides 9425 N of pull force at the same pressure, offering a lighter and more compact alternative. The adjustable stroke is highly beneficial for machines requiring variable end stops or fine-tuning during product changeover, whereas a fixed-stroke SAI cylinder is sufficient for rigid, unchanging travel requirements.
For ISO 15552 replacement matching, verify the 200 mm bore, 130 mm stroke, 20 mm adjustment, PT G3/4 port, and the SUS420J2 rod material. Because the nominal stroke is 130 mm, side-load is manageable, but always guide long unsupported loads. Note that this plain SAIJ does not hold position without live air; for fail-safe load holding, consider the SAIL or BSAI series instead. Mounting options are limited to 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 SAIJ200AX130-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder delivers 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can generate up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that trims the effective travel. For this model, the 130 mm nominal stroke can be dialed back by up to 20 mm, creating a 110-130 mm usable travel window for fine-tuning at commissioning.
