About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-10
The AirTAC SAIJ200X45-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 15708N push force at 0.5 MPa, making it suited for heavy-duty positioning. The built-in rear stopper allows you to fine-tune the travel window from 35 to 45 mm during commissioning without adding external stops.
This unit includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance. It uses PT tapered ports and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-10 Is Used
Heavy Press Setup
Fine-tune the 35-45 mm stroke end-position precisely during machine commissioning to ensure perfect pressing depth on heavy components.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slight thickness variations when switching product runs on a line.
Short-Stroke Clamping
Deliver up to 15708N of clamping force at 0.5 MPa on short travel distances without relying on external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-10 the Right Cylinder?
Choose this 200 mm bore when you need massive thrust, such as 15708N push at 0.5 MPa, to move heavy fixtures. If you can step down to a 160 mm bore, you will see a lower 10053N push force but a lighter footprint. The 10 mm adjustment range is ideal for dialing in exact end positions on a short 45 mm stroke. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load holding, use an external rod lock or a SAIL cylinder. It mounts via Basic, FA, LB, TC, FTC, TCM1, or TCM2 interfaces.
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 SAIJ200AX45-10 FAQ
The rear adjuster screw lets you shorten the 45 mm nominal stroke by up to 10 mm, creating a 35-45 mm usable travel window. It acts as a mechanical stop to fine-tune the end position without swapping the cylinder.
At 0.5 MPa, it provides a push force of 15708N and a pull force of 15080N. At 0.7 MPa, the push force increases to 21991N.
