About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-10S
The AirTAC SAIJ200X325-10-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a robust 15708 N push force at 0.5 MPa. It features a rear stroke adjuster that permits a 10 mm trim, creating a precise 315-325 mm usable travel window for exact end-position tuning during commissioning. This made-to-order 325 mm stroke variant is equipped with a SUS420J2 stainless steel piston rod and a -S magnet for position sensing.
Because the 325 mm stroke exceeds the standard 1500 mm maximum for this bore family, it is built as a non-standard configuration. The extruded aluminum barrel incorporates sensor grooves on both sides, seamlessly accommodating CMSE reed and DMSE solid-state switches. The rear stopper screw acts purely as a travel end-deceleration device, meaning it will not hold a load safely without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-10S Is Used
Heavy Pressing Operations
Delivers up to 21991 N of push force at 0.7 MPa for heavy-duty forming, pressing, and clamping tasks requiring substantial power.
Product Changeover Adjustment
The 10 mm rear adjuster allows operators to fine-tune the 325 mm stroke window during product size transitions without changing the cylinder setup.
Large Material Handling
Ideal for moving heavy structural components, where the 40 mm SUS420J2 rod and M36x2 thread provide high resistance against side loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-10S the Right Cylinder?
Selecting this 200 mm bore size provides immense thrust, pushing 15708 N at 0.5 MPa and 21991 N at 0.7 MPa, which is ideal if you are scaling up from a 160 mm bore that yields 10053 N at 0.5 MPa. You would step down to the 160 mm option if your application requires less than 10 kN of force to save space and air consumption. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product-size changeovers on a line, allowing fine-tuning without swapping the cylinder or adding external stops.
For ISO 15552 replacement matching, verify the 200 mm bore, 325 mm stroke, 10 mm adjustment, PT tapered G3/4 port, and the -S magnet requirement. Given the 325 mm stroke, the 40 mm rod diameter and M36x2 thread handle substantial side loads, but an external guide is still recommended for unsupported loads. Remember that the adjuster is a stop, not a lock; for load-holding without live pressure, consider the SAIL or BSAI series instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ200AX325-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm, creating a 315-325 mm usable stroke window. This stopper fine-tunes the end position but does not lock the load without live air pressure.
