About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-20
The AirTAC SAIJ200X220-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 200-220 mm usable travel window. In this configuration, the heavy-duty 40 mm rod is machined from SUS420J2 stainless steel (code A) for superior corrosion resistance, and air connections use PT tapered threads. Operating at 0.15-1.0 MPa, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This massive bore achieves a maximum thrust of 3204 kgf at 1.0 MPa, making it ideal for high-force pressing. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though no magnet is installed in this base version. The rear stopper screw allows precise end-position tuning during commissioning without adding external physical stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-20 Is Used
Heavy Pressing Operations
Delivers 15708 N of push force at 0.5 MPa for forming, stamping, and assembling heavy components, with the 20 mm rear adjuster allowing precise bottoming-out tuning.
Product Changeover
Quickly adapt the end-of-stroke position within the 200-220 mm travel window when switching production lines to different material thicknesses without swapping cylinders.
Automated Clamping
Provides 15080 N of pull force for securing large workpieces, utilizing the SUS420J2 stainless rod to resist corrosion in humid or washdown industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-20 the Right Cylinder?
Select this 200 mm bore when an application requires extreme force, such as 15708 N of thrust at 0.5 MPa, which is a significant step up from the 160 mm bore that provides 10053 N. The 20 mm adjustment range is specifically valuable for fine-tuning heavy pressing or holding positions during machine setup and product changeover, offering flexibility a fixed-stroke SAI cylinder cannot match. The robust 40 mm SUS420J2 stainless rod handles high side loads well, but because the 220 mm stroke is substantial, an external guide should be used to prevent premature seal wear.
For dimensionally interchangeable ISO 15552 replacement, match the 200 mm bore, 220 mm stroke, 20 mm adjustment code, PT port threads, and the SUS420J2 rod material (code A). Remember that the rear adjuster is strictly a travel stop, not a locking device; it cannot hold the load without continuous live air pressure. For true load-holding without air, consider an AirTAC SAIL or BSAI cylinder, or an external rod lock. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ 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 SAIJ200AX220-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum 1.0 MPa operating pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as an external stopper that allows you to shorten the nominal 220 mm stroke by up to 20 mm, creating a 200-220 mm usable travel window. This enables fine end-position tuning at commissioning without adding external stops, but it does not lock the load without live air pressure.
