Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30S
The AirTAC SAIJ200X30-30-S 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 40mm carbon steel rod upgraded with an SUS420J2 stainless steel surface (code A) for superior corrosion resistance. Because the nominal stroke is 30mm and the adjustment range is 30mm, operators can dial the effective travel down to a 0-30mm window for exact end-position tuning.
This adjustable-stroke design allows fine-tuning at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches. It uses a PT G3/4 port and operates at speeds of 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30S Is Used
Heavy-Duty Pinching
Provides variable end-stops for high-force pinching or pressing tasks, allowing operators to dial in the exact 0-30mm travel needed for different material thicknesses.
Product Changeovers
Enables rapid machine setup and product-size changeovers on automated lines by fine-tuning the rear stopper position without physically replacing the cylinder.
Short-Stroke Clamping
Delivers up to 3204kgf of clamping force in compact spaces where a standard long-stroke cylinder would not fit, using the adjustable screw to set the precise grip depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX30-30S the Right Cylinder?
Choose this 200mm bore cylinder when an application requires extreme force combined with a very short, highly precise travel distance. If the 3204kgf maximum thrust at 1.0 MPa is excessive, stepping down to a 160mm bore yields 10053N push force at 0.5 MPa, which may better suit lighter loads. The SAIJ200X30-30-S is selected specifically for its 0-30mm adjustable window, allowing variable end-stops during machine setup or product-size changeovers.
For ISO 15552 replacement matching, verify the 200mm bore, 30mm nominal stroke, PT G3/4 port, and the -S magnet requirement. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Note that the rear adjuster acts strictly as a travel stop, not a lock; it cannot hold a load without live air. For load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.

- ✓ 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 SAIJ200AX30-30S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204kgf.
The rear adjusting screw acts as a mechanical stopper that can shorten the effective travel by up to 30mm. Since the nominal stroke is 30mm, this creates a 0-30mm usable travel window, allowing you to fine-tune the end position at commissioning without changing the cylinder.
