About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-100
The AirTAC SAIJ200X950-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 850 to 950 mm, allowing you to dial back the nominal 950 mm stroke by up to 100 mm during machine setup. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This heavy-duty actuator utilizes a 40 mm carbon steel rod with an M36x2 thread, providing high rigidity against side loads, though external guiding remains essential for this long stroke. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops, while the standard variable air cushions handle deceleration. It is not a load-holding lock; for fail-safe positioning without live air, consider the SAIL or BSAI series.

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 SAIJ200X950-100 Is Used
Heavy Machinery Positioning
Dial in the exact 850-950 mm travel window to position massive fabrication components without re-engineering fixed stops.
Product Changeover
Quickly adjust the end-stop to accommodate new large-scale product dimensions on the fly during line transitions.
Assembly Press Tuning
Fine-tune the stroke end-point during commissioning to achieve precise clamping forces on heavy assembly presses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-100 the Right Cylinder?
Choose this 200 mm bore when the 160 mm variant (delivering 9425 N pull at 0.5 MPa) is insufficient for your heaviest positioning tasks. An adjustable stroke is selected over a fixed SAI model when you need precise end-position tuning at commissioning or during product changeovers, trimming the travel back by up to 100 mm without swapping the cylinder. When matching an ISO 15552 replacement, verify the 950 mm stroke, 100 mm adjustment range, G3/4 PT port, and standard carbon steel rod. Because the stroke is 950 mm, an external guide is mandatory to prevent rod damage and premature seal wear.

- ✓ 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 SAIJ200X950-100 FAQ
At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw lets you mechanically shorten the effective travel from 950 mm down to 850 mm. It acts as a stop to fine-tune the end position, but it does not lock the load without live air pressure.
