About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-40S
The AirTAC SAIJ200X450-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the end position during commissioning. With a 450 mm nominal stroke and a 40 mm adjustment range, it provides a usable travel window of 410-450 mm.
The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves. It features a robust 40 mm carbon steel rod with an M36x2 thread, PT tapered ports, and variable air cushions at both ends. The rear adjuster acts purely as a travel stop for deceleration, meaning it will not hold the load without live air pressure.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-40S Is Used
Heavy Press Fine-Tuning
Dial in the exact 410-450 mm end-stop during machine setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Adjust the stroke on the fly for different package sizes on a heavy-duty conveyor line, using the rear stopper to set the new travel limit.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-40S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires substantial thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The adjustable 410-450 mm window is ideal for product changeovers or setup fine-tuning, eliminating the need to swap cylinders or bolt on external stops. For load-holding without continuous air pressure, this plain SAIJ requires an external rod lock or a different series like the SAIL or BSAI.
Because the 450 mm stroke is significant, the 40 mm rod and M36x2 thread handle high stresses, but an external guide is recommended to prevent excessive side-loading on the piston. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using a reduced set of accessories: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200X450-40S FAQ
The rear adjuster screw lets you shorten the 450 mm nominal stroke by up to 40 mm, creating a 410-450 mm travel window. This stopper only sets the end position and decelereration; it does not lock the load without live air pressure.
