About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-50S
The AirTAC SAIJ200X170-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa, with a maximum capacity of 3204 kgf at 1.0 MPa. The built-in rear stopper allows you to fine-tune the travel window down from 170 mm to a 120-170 mm range during commissioning.
This variant uses an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. It includes a magnetic piston for position sensing, compatible with AirTAC CMSE reed and DMSE solid-state switches mounted in the dual-side sensor grooves. Fluid ports are PT tapered threads, and the extruded aluminum barrel design omits tie-rods for a rigid, compact footprint.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-50S Is Used
Heavy Press Tuning
Dial in the exact 120-170 mm travel window on large stamping presses during setup, absorbing high kinetic energy using the 50 mm air cushion.
Automated Assembly Forming
Apply up to 3204 kgf of push force to form heavy components, using the rear stopper to micro-adjust end positions for different product runs.
Large Valve Actuation
Actuate massive industrial valves where the exact 170 mm stroke needs a 50 mm trim-back capability to prevent mechanical over-travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-50S the Right Cylinder?
Choose this 200 mm bore when 160 mm bore models (providing 10053N push at 0.5 MPa) lack sufficient force. The 50 mm adjustment range is ideal for dialing in exact end-of-stroke positions on large machinery without adding external stops. Because the 170 mm stroke is under the 300 mm side-load threshold, the robust 40 mm rod handles normal dynamics well, though heavy radial loads still require external guides.
Remember that the rear adjuster acts only as a travel stop to set deceleration alongside the 50 mm air cushions; it does not hold the load without live air pressure. For position holding without continuous air, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead of this SAIJ model. This SKU is dimensionally interchangeable per ISO 15552, configured with PT ports, SUS420J2 rod, -S magnet, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAIJ200AX170-50S FAQ
At a 0.5 MPa operating pressure, it provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, the push force reaches 21991N, yielding a maximum thrust of 3204 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 170 mm stroke by up to 50 mm, creating a 120-170 mm usable travel window. This stopper sets the end position but does not lock the load without live air pressure.
