Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-50S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 60mm 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 SAIJ200AX60-50S
The AirTAC SAIJ200X60-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 15708N push force at 0.5 MPa and features a usable travel window of 10-60mm, letting you dial back the 60mm nominal stroke by up to 50mm. The barrel is extruded aluminum with sensor grooves on both sides, and the -S magnet enables precise tracking with AirTAC CMSE reed and DMSE electronic switches.
This variant uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to fine-tune the end position at commissioning; it is not a lock and will not hold the load without live air. For position holding without pressure, consider a SAIL or BSAI cylinder, or an external rod lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-50S Is Used
Press Tonnage Calibration
Dial in the exact 10-60mm travel window during press setup to accommodate different material thicknesses without physically swapping the actuator.
Assembly Line Changeover
Rearrange the end-stop quickly on an automated line when switching between product sizes, using the 50mm adjustment range to fine-tune the retraction point.
Heavy Clamping Fixtures
Securely clamp large workpieces using the 15708N push force, adjusting the mechanical stopper to prevent over-travel on delicate assemblies.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-50S the Right Cylinder?
Choose this 200mm bore adjustable cylinder when your application requires 15708N of push force at 0.5 MPa (or up to 3204 kgf at 1.0 MPa) but demands variable end-stops for rapid product changeover. If you need less force, stepping down to a 160mm bore yields 10053N push at 0.5 MPa. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. To match this ISO 15552 replacement, verify the 60mm stroke, 50mm adjustment, PT port, and -S magnet.
Because the stroke is short, side-loading from unsupported weight is less severe than with long-stroke units, but the 40mm rod and M36x2 thread still require proper alignment to prevent seal wear. The rear stopper allows fine end-position tuning without swapping the cylinder or adding external stops, though the variable air cushion at both ends only manages deceleration, not load holding.

- ✓ 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 SAIJ200AX60-50S FAQ
The rear adjuster is a mechanical stopper that lets you shorten the effective stroke from 60mm down to as little as 10mm, creating a 10-60mm usable travel window. It allows fine end-position tuning at commissioning without adding external stops, but it does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, it provides 15708N of push force and 15080N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
