About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-20S
The AirTAC SAIJ200X950-20-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty operations. It features a rear mechanical adjuster that allows you to dial back the nominal 950 mm stroke by up to 20 mm, creating a precise 930-950 mm usable travel window for commissioning without external stops. In this -S configuration, the extruded aluminum barrel includes a magnet for direct CMSE reed or DMSE electronic solid-state sensors.
The carbon steel piston rod utilizes an M36x2 thread, and the unit is plumbed with PT tapered G3/4 ports. Variable air cushions at both ends manage deceleration, but remember the rear adjuster is a travel stop, not a lock; it will not hold a 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 SAIJ200X950-20S Is Used
Heavy Press End-Stop Tuning
Dial in the exact 930-950 mm retraction point on a large assembly press during tooling setup, using the rear adjuster to compensate for fixture thickness without changing the cylinder.
Pallet Positioning Changeover
Accommodate varying pallet lengths on a heavy-duty transport line by adjusting the stroke end position by up to 20 mm during product format changes, ensuring precise stops.
Large Mold Clamping
Provide up to 3204 kgf of clamping force at 1.0 MPa to secure large industrial molds, using the adjustable stop to set the exact clamping depth during commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-20S the Right Cylinder?
The 20 mm rear adjustment screw is ideal for fine-tuning the end-of-stroke position during machine setup or product changeover, eliminating the need to swap physical cylinders when minor dimensional variances occur. To replace this ISO 15552 unit, match the 200 mm bore, 950 mm stroke, 20 mm adjustment range, PT G3/4 ports, and the -S magnet requirement.
Because the 950 mm stroke is substantial, the M36x2 carbon steel rod will experience amplified bending moments under high side loads; an external guide rail is strongly recommended to prevent rod damage and premature seal failure. For applications requiring true load-holding without continuous air pressure, a plain SAIJ cylinder is insufficient—consider the AirTAC SAIL pneumatic lock series or an external rod lock instead of relying on the rear stopper.
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 SAIJ200X950-20S FAQ
At its maximum 1.0 MPa pressure, it delivers 3204 kgf of push force.
The rear mechanical stopper allows you to shorten the 950 mm nominal stroke by up to 20 mm, providing a 930-950 mm travel window. This stopper sets the end position but does not lock the load; live air pressure is required to hold position.
