About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-30S
The AirTAC SAIJ200X200-30-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks requiring precise end-position tuning. It features a 200mm nominal stroke that can be dialed back by up to 30mm via a rear adjusting screw, creating a 170-200mm usable travel window. This on-cylinder fine-tuning eliminates the need to swap components or bolt on external stops during machine commissioning. Delivering 15708N of push force at 0.5 MPa, it handles massive loads with ease.
This specific SKU is configured with an SUS420J2 stainless steel rod (code A) for superior corrosion resistance and a PT tapered port thread for a robust pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides, and because this model includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. The 40mm rod diameter and M36x2 thread provide exceptional rigidity, though long unsupported strokes still necessitate an external guide to manage side loads.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-30S Is Used
Heavy Press Tuning
Dial in the exact 170-200mm end-stop position during heavy press commissioning without swapping cylinders or adding external mechanical stops.
Product Size Changeover
Quickly adjust the retract stroke by up to 30mm on packaging lines to accommodate different product sizes on the fly.
Large Load Positioning
Leverage the 15708N push force and rigid 40mm rod to move heavy pallets or assemblies, fine-tuning the landing position at the rear.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-30S the Right Cylinder?
Select this 200mm bore cylinder when your application demands immense thrust—stepping down to a 160mm bore drops the 0.5 MPa push force to 10053N, whereas this SAIJ200X200-30-S delivers 15708N. The integrated 30mm rear adjuster is ideal for variable end-stops and product-size changeovers, offering setup flexibility that a fixed-stroke SAI cylinder cannot match. When outfitting your machinery, ensure you specify the PT port thread, the SUS420J2 rod material, and the -S magnet for CMSE/DMSE sensors.
Keep in mind that the rear adjuster acts purely as a travel stop and works alongside the standard air cushions to decelerate the load; it does not hold the load in place without live air pressure. For true fail-safe load holding without continuous pneumatic pressure, you must integrate an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAI series cylinder. Operating speed is capped at 30-500 mm/s for this large bore size.

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 SAIJ200AX200-30S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you trim the effective stroke back by up to 30mm, providing a usable travel window of 170-200mm. It is a travel stop that works with the air cushions to decelerate the load, not a lock, so it will not hold the load without live air pressure.
At a 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can achieve up to 3204 kgf at the maximum 1.0 MPa operating pressure.
