About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-30S
The AirTAC SAIJ200X950-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 30 mm. This yields a usable 920-950 mm stroke window, allowing precise end-position tuning at commissioning without swapping the barrel or adding external stops. As the largest bore in the series, it delivers immense thrust, pushing 21991 N at 0.7 MPa and 28274 N at 0.9 MPa.
Equipped with a -S magnet, this unit interfaces directly with AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side extruded aluminum barrel grooves. It uses a robust 40 mm carbon steel rod with an M36x2 thread, G3/4 PT ports, and 50 mm cushions at both ends. The rear adjuster acts purely as a travel stop and deceleration setter, not a lock, so it cannot 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.

Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-30S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers, offering a 920-950 mm travel window. Because the stroke extends to 950 mm, an external guide is highly recommended to manage side loads on the 40 mm rod and prevent premature wear.
For ISO 15552 replacement matching, verify the 200 mm bore, 950 mm nominal stroke, 30 mm adjustment range, G3/4 PT ports, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. If true load-holding without live air is required, this plain cylinder will not suffice; instead, look to the SAIL air-released lock or BSAI clamp-lock variants.
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 SAIJ200X950-30S FAQ
It reaches a maximum of 3204 kgf at 1.0 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 950 mm nominal stroke by up to 30 mm, creating a 920-950 mm usable travel window. It only sets the end position and does not lock the load without live air.
