Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-40S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 75mm 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 SAIJ200AX75-40S
The AirTAC SAIJ200X75-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 35-75 mm from its 75 mm nominal stroke. As the largest standard bore, it generates a substantial 15708 N of push force at 0.5 MPa, making it suitable for heavy-duty pressing and positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet interfaces directly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection.
This variant features an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and pairs with PT tapered port threads. The rear adjustment screw acts strictly as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device; the cylinder relies on live air pressure to hold a load. For fail-safe load holding without air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-40S Is Used
Heavy-Duty Pressing
Apply up to 15708 N of push force at 0.5 MPa for assembling large components, using the 35-75 mm travel window to fine-tune the exact crimp depth.
Product Changeover
Quickly adjust the retract end-stop by up to 40 mm during line changeovers to handle different product sizes without swapping the cylinder.
Position Sensing
Leverage the integrated -S magnet with DMSE solid-state or CMSE reed switches to confirm end-of-stroke in automated heavy machinery.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-40S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when an application demands high thrust, such as 15708 N push or 15080 N pull at 0.5 MPa. If the force requirement is lower, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa, which reduces air consumption and physical footprint. The adjustable stroke is chosen over a fixed SAI cylinder when a machine requires variable end-stops to accommodate product size changeovers or to dial in exact positioning during setup.
When replacing this unit within an ISO 15552 footprint, match the 200 mm bore, 75 mm stroke, 40 mm adjustment range, PT G3/4 port threads, and the -S magnet requirement. The 40 mm diameter rod and M36x2 thread provide high rigidity, but even with a robust rod, any application approaching the maximum stroke limits should use an external guide to prevent side-loading damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ200AX75-40S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N push force and 15080 N pull force. The operational speed range is 30-500 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective stroke back by up to 40 mm from the 75 mm nominal length, yielding a 35-75 mm travel window. It only sets the end position and does not lock the load.
