About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-30S
The AirTAC SAIJ200X45-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its 45mm nominal stroke can be precisely dialed back by up to 30mm, yielding a fine-tunable 15-45mm usable travel window. This makes it exceptionally effective for heavy-duty applications requiring exact end-position calibration without mechanical rework.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. It utilizes PT tapered ports sized at G3/4 and incorporates adjustable air cushions at both ends to decelerate its high-inertia loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-30S Is Used
Heavy Press Tuning
Dial in the exact 15-45mm crushing or pressing depth for thick materials without swapping out the massive 200mm bore cylinder.
Product Size Changeover
Quickly adjust the rear stopper by up to 30mm to accommodate different product heights on a heavy-duty assembly line.
Robotic End Effectors
Utilize the 15708N thrust and integrated CMSE/DMSE sensor feedback for precise positioning of large industrial grippers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-30S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application demands extreme force, such as 15708N push or 15080N pull at 0.5 MPa. If the full 200mm bore capacity is excessive, stepping down to a 160mm bore provides 10053N of push force. You choose the SAIJ adjustable-stroke configuration over a fixed SAI model when you need on-the-fly end-stop tuning during product changeovers. Because the stroke is 45mm, external side-load guides are less critical than on long-stroke units, though the robust 40mm rod and M36x2 thread naturally handle substantial side loads.
For an exact ISO 15552 replacement, match the 200mm bore, 45mm stroke, 30mm adjustment range, G3/4 PT ports, and the -S magnet requirement. Remember that the rear adjuster functions strictly as a travel stop, not a locking device; it cannot hold a load without continuous live air pressure. If positive load-holding is required without air pressure, consider an AirTAC SAIL or BSAI cylinder instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ200AX45-30S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of thrust.
The rear adjuster screw allows you to shorten the 45mm nominal stroke by up to 30mm, creating a usable travel window of 15-45mm. This stopper only limits the travel end and does not lock the load without live air pressure.
