About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-40S
The AirTAC SAIJ200X500-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 500 mm travel by up to 40 mm. This yields a precise 460-500 mm usable window, allowing exact end-position tuning at commissioning without swapping the hardware or adding external stops. It delivers massive thrust, pushing 28274 N and pulling 15080 N at 0.9 MPa.
This heavy-duty unit features a 40 mm diameter piston rod with an M36x2 thread, providing exceptional rigidity for high side-load capacity, though the long 500 mm stroke still necessitates an external guide to prevent rod binding. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches, while the SUS420J2 stainless steel rod (code A) offers superior corrosion resistance.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-40S Is Used
Heavy Press Tuning
Fine-tune the 460-500 mm stroke end-position precisely during press setup, absorbing mechanical variance without machining new spacer blocks.
Product Changeover
Quickly adapt the cylinder's travel window on automated assembly lines when switching between product variants of different sizes.
Guided Heavy Load
Move heavy payloads with up to 28274 N of thrust while relying on the massive 40 mm rod and external guides to handle structural side-loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-40S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your process requires up to 3204 kgf of peak force at 1.0 MPa; stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053 N. The adjustable 40 mm travel window is ideal for product-size changeovers on a line, offering variable end-stops that a fixed-stroke SAI cylinder cannot match. Note that the rear adjuster acts purely as a mechanical stop for deceleration—it does not hold the load without live air. For true load-holding without pneumatic pressure, consider an SAIL air-released lock, a BSAI clamp-lock, or an external pilot-operated check valve.
To match this ISO 15552 interchangeable cylinder, specify a 200 mm bore, 500 mm stroke, 40 mm adjustment range, PT tapered port thread, and the -S magnet option. The supported mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

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 SAIJ200AX500-40S FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder provides a push force of 28274 N and a pull force of 15080 N. The maximum theoretical force at 1.0 MPa is 3204 kgf.
The rear adjuster acts as a mechanical stop that shortens the effective travel from the 500 mm nominal stroke. It provides a usable 460-500 mm window, allowing you to trim the retract end-position by up to 40 mm during commissioning without affecting the extend stroke or requiring cylinder replacement.
