About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X240-75S
The AirTAC SAIJ200X240-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N at 0.5 MPa and up to 28274 N at 0.9 MPa. The integrated -S magnet enables position feedback via CMSE reed or DMSE electronic solid-state sensors housed in the dual-side barrel grooves. A standard PT tapered port and carbon steel rod ensure robust pneumatic connectivity and structural integrity.
With a 240 mm nominal stroke and a 75 mm adjustment range, this SKU provides a usable travel window of 165 to 240 mm. This allows precise end-position tuning during commissioning without swapping the cylinder. The adjuster acts purely as a mechanical stop for deceleration and does not lock the load; use an external rod lock or SAIL cylinder for load-holding 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 SAIJ200X240-75S Is Used
Heavy Press Tuning
Dial in the exact 165-240 mm end-position on heavy pressing tasks without machining external stopper blocks.
Product Changeover
Quickly adjust the stroke window during line size changeovers, saving downtime on large format packaging systems.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X240-75S the Right Cylinder?
The adjustable 165-240 mm window is ideal for heavy product changeovers where exact end-stops vary. Although the 40 mm carbon steel rod handles high axial loads, an external guide is recommended for this 240 mm stroke to prevent side-loading damage.
For a direct ISO 15552 replacement, match the 200 mm bore, 240 mm nominal stroke, 75 mm adjuster, PT port thread, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The rear screw sets the retract end, but a plain SAIJ does not hold position without live air; select a BSAI clamp-lock for pneumatic braking.
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 SAIJ200X240-75S FAQ
At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw trims the effective travel back by up to 75 mm, creating a 165-240 mm usable stroke window. It functions as a mechanical stop, not a lock.
