About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-75
The AirTAC SAIJ200X950-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its 75mm adjustment screw allows you to dial back the 950mm nominal stroke, creating an exact 875-950mm usable travel window for fine-tuning end positions without external stops. It features a robust 40mm carbon steel rod and a G3/4 PT tapered port to handle high flow requirements.
This extruded aluminum profile cylinder includes variable air cushions at both ends to manage the kinetic energy of heavy loads. The rear adjuster acts purely as a travel stop for position tuning and does not lock the load; for position holding without live air, consider the SAIL or BSAI series. It supports standard SAIJ mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200X950-75 Is Used
Heavy Press Tuning
Fine-tune the 875-950mm travel window during setup to achieve the exact bottoming position for large stamping or pressing tasks without adding external mechanical stops.
Large Product Changeover
Adjust the rear stopper by up to 75mm to accommodate different pallet or product sizes on a heavy-duty transfer line, minimizing downtime between production runs.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-75 the Right Cylinder?
The adjustable stroke is particularly valuable during machine commissioning or product changeovers, allowing you to shift the end-stop by up to 75mm rather than swapping out a fixed-stroke SAI cylinder. Because the 950mm stroke is substantial, the 40mm rod will still experience leverage forces; always use an external guide to prevent side-loading damage.
When specifying a replacement, verify the 200mm bore, 950mm nominal stroke, 75mm adjustment range, G3/4 PT port, and the required mounting kit. This model does not include a magnet; if sensor feedback is required, select a -S variant and use AirTAC CMSE reed or DMSE electronic switches mounted in the dual sensor grooves. Operating speed for this bore is rated at 30-500mm/s.
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 SAIJ200X950-75 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw lets you shorten the 950mm nominal stroke by up to 75mm, providing an effective travel window of 875-950mm. This stopper only sets the end position; it does not lock the load without continuous air pressure.
