About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-50S
The AirTAC SAIJ200X260-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the effective travel by up to 50 mm. This creates a highly versatile 210-260 mm usable travel window, making it ideal for fine-tuning end positions during machine commissioning without swapping out the barrel. Delivering exceptional thrust, it provides 15708 N of push force and 15080 N of pull force at a 0.5 MPa operating pressure.
This specific SKU is configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S model, it is factory-fitted with a magnet compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors. The robust M36x2 rod thread handles high side loads, while variable air cushions at both ends manage end-of-stroke deceleration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-50S Is Used
Heavy Press Tuning
Dial in the exact pressing depth of large industrial assemblies over the 210-260 mm window during setup, allowing precise end-position adjustments without changing the cylinder.
Product Changeover Stops
Adapt a heavy-duty diverter or stopper block on a packaging line to new product sizes by adjusting the rear stroke stopper, saving time on format changeovers.
Large Fixture Clamping
Secure oversized workpieces in machining fixtures where the 15708 N push force provides immense holding power and the adjustable stroke accommodates varying part tolerances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-50S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force output—up to 15708 N at 0.5 MPa—and the ability to precisely tune the retract end-position over a 50 mm range. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may offer a more compact footprint. The rear adjuster screw acts purely as a mechanical travel stop for commissioning and product changeovers; it does not hold the load without live air pressure. For genuine fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series instead.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 260 mm nominal stroke, 50 mm adjustment range, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. Because the 260 mm stroke is relatively short for this massive bore, standard side-load concerns are minimal, but an external guide is still recommended for heavy radial loads. The operating speed range is 30-500 mm/s.

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 SAIJ200AX260-50S FAQ
The rear of the cylinder features an external adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 50 mm. This provides a usable travel window of 210-260 mm, which is ideal for fine-tuning end positions at commissioning without adding external stops.
At a standard 0.5 MPa operating pressure, the SAIJ200X260-50-S delivers 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 28274 N at 0.9 MPa.
