About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-30
The AirTAC SAIJ200X190-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. It features a robust 200mm bore paired with a 190mm stroke, yielding a massive 28274N of push force at 0.9 MPa. A rear-mounted stopper screw allows you to fine-tune the effective travel down to 160mm, providing a precise 160-190mm adjustment window for product changeovers without adding external stops.
This variant utilizes a SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and fluid is supplied via a PT G3/4 port. Operating at speeds of 30-500 mm/s, the unit relies on adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-30 Is Used
Heavy Press Tuning
Dial in the exact 160-190mm end position for large metal forming or press operations, ensuring precise contact without repositioning the entire fixture.
Product Changeover
Quickly adjust the stroke length on automated packaging lines to handle different carton or pallet sizes without swapping out the cylinder.
Automated Assembly
Fine-tune the clamping travel for heavy automotive components during assembly, using the rear stopper to compensate for mechanical tolerances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-30 the Right Cylinder?
Selecting this 200mm bore model is appropriate when your process demands up to 28274N of thrust at 0.9 MPa. If your force requirements are lower, stepping down to a 160mm bore yields 18095N under the same pressure, which may better suit mid-range loads. The adjustable stroke is chosen over a fixed SAI cylinder when you need live commissioning adjustments or variable end-stops to accommodate multiple product sizes on one machine.
For any stroke length approaching or exceeding 300mm, long unsupported loads require an external guide to prevent rod side-loading. Furthermore, the rear adjuster and air cushions act only as travel stops and deceleration devices—they do not hold the load without live air pressure. For secure load-holding, consider an external rod lock, pilot-operated check valve, or the AirTAC BSAI clamp-lock series. This unit is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ200AX190-30 FAQ
At an operating pressure of 0.9 MPa, this 200mm bore cylinder provides a push force of 28274N and a pull force of 15080N.
The rear stopper screw allows you to shorten the 190mm nominal stroke by up to 30mm, creating a usable travel window of 160-190mm. The adjuster acts as a mechanical stop and does not lock the load without continuous air pressure.
