About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-30S
The AirTAC SAIJ200X195-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suited for heavy-duty automation. By turning the rear screw, you achieve a usable travel window of 165-195 mm, allowing precise end-position tuning without swapping hardware.
This unit features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. It uses a G3/4 port and omits FB, CA, CB, and CR mounts, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-30S Is Used
Heavy Pressing Operations
Dial in the exact 165-195 mm travel window during setup to apply maximum pressing force without bottoming out the tooling on every cycle.
Product Size Changeover
Quickly readjust the rear stopper on a packaging line to accommodate different large-format product sizes without changing the cylinder.
Large Fixture Clamping
Fine-tune the clamping end-position on heavy fixtures, relying on the massive 15708 N push force to secure oversized components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-30S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme force alongside a variable end-stop, such as pressing or heavy clamping tasks where a fixed 195 mm stroke might overrun. If 15708 N of push force at 0.5 MPa is excessive, stepping down to a 160 mm bore yields 10053 N, simplifying mounting and air consumption. Conversely, if your setup requires holding a load securely without continuous live air pressure, note that this adjuster acts only as a travel stop, not a brake. You would need an external rod lock or an AirTAC SAIL cylinder for positive holding.
For an exact ISO 15552 replacement match, verify the 200 mm bore, 195 mm nominal stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet option. Because the stroke is 195 mm, standard side-load rules apply, but always ensure external guiding for a rod of this mass. The operational speed range is 30-500 mm/s.
Quick checklist
- ✓ 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 SAIJ200AX195-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 165-195 mm from the nominal 195 mm stroke, letting you fine-tune the end position at commissioning without adding external stops.
