About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-40S
The AirTAC SAIJ200X950-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it suited for heavy industrial handling. The integrated -S magnet allows direct mounting of CMSE reed and DMSE electronic sensors along the dual extruded barrel grooves for precise position detection.
With a 950mm nominal stroke and a 40mm adjustment range, this model provides a usable travel window of 910-950mm. You can fine-tune the retract end-position at commissioning without external stops. The rear adjuster acts purely as a travel stop for deceleration alongside the 50mm air cushions, and 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 SAIJ200X950-40S Is Used
Variable Retract Stops
The 40mm rear adjuster allows operators to change the effective 910-950mm stroke window quickly during machine setup or product line changeovers.
Automated Assembly Lines
Dual sensor grooves support CMSE and DMSE switches for reliable end-position feedback in high-speed, heavy-duty automated manufacturing.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-40S the Right Cylinder?
The adjustable 910-950mm travel window is ideal for product changeovers, allowing you to dial in the exact retract distance on the fly rather than swapping to a fixed-stroke SAI cylinder. For a true ISO 15552 replacement match, verify the 950mm stroke, 40mm adjustment, PT tapered port threads, and the -S magnet requirement.
Because the 950mm stroke is substantial, the 40mm carbon steel rod and M36x2 thread will still experience deflection under high side loads; an external guide rail is recommended to prevent premature seal wear. Remember that the rear adjuster only sets the travel end, functioning as a stop rather than a lock. For dead-load holding without live air, consider an AirTAC SAIL or BSAI cylinder. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200X950-40S FAQ
At its maximum 1.0 MPa pressure, it achieves up to 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 950mm nominal stroke by up to 40mm, creating a 910-950mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
