About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-75S
The -75 adjustment code creates a usable travel window between 200 and 275 mm, allowing precise end-position tuning without swapping the unit. A PT tapered port thread and carbon steel rod come standard on this bore.
This magnet-equipped variant (-S) integrates directly with AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves. The rear stopper acts solely as a travel limit for commissioning flexibility, not a load-holding brake. For dead-load security without live air pressure, an external rod lock or the AirTAC SAIL/BSAI series is required.

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 SAIJ200X275-75S Is Used
Heavy Press Tuning
Dial in the exact 200-275 mm end-of-stroke position for heavy pressing operations during setup, ensuring precise contact without reconfiguring the entire machine frame.
Product Changeover Stops
Adjust the retract stopper by up to 75 mm to accommodate varying package lengths on a conveyor line, enabling rapid product changeovers without replacing the actuator.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-75S the Right Cylinder?
Choose this 200 mm bore when an application requires heavy thrust up to 15708 N at 0.5 MPa, stepping up from a 160 mm bore that provides 10053 N. The 75 mm adjustment window is ideal for product-size changeovers on a line, negating the need to physically swap a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, specify the 200 mm bore, 275 mm nominal stroke, 75 mm adjuster, PT G3/4 port, and the -S magnet option.
With a 275 mm stroke exceeding the 300 mm external guide threshold is not triggered, but the 40 mm rod diameter and M36x2 thread handle substantial side loads. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ200X275-75S FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 75 mm from the 275 mm nominal stroke, creating a 200-275 mm usable window. It functions as a mechanical stop for end-position tuning, not a lock.
