About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-75S
The AirTAC SAIJ200X950-75-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications. Equipped with a magnet, it supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side extruded aluminum barrel grooves.
This model features a rear-mounted mechanical stopper that provides an 875-950mm usable travel window, allowing you to trim the 950mm nominal stroke by up to 75mm. This built-in adjuster simplifies commissioning and product changeovers without requiring external stops. The rear adjuster and variable air cushions strictly manage end-of-stroke deceleration; they do 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 SAIJ200X950-75S Is Used
Heavy Press Positioning
Dial in the exact 875-950mm end-stop during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Large Conveyor Diverter
Adjust the retract position on the fly during product size changeovers to precisely control where large loads are pushed off a main conveyor line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-75S the Right Cylinder?
Select this 200mm bore cylinder when an application requires substantial thrust—stepping down to a 160mm bore drops the 0.5MPa push force to 10053N. The adjustable 875-950mm travel window is ideal for machinery requiring precise end-position tuning during setup or format changes, offering flexibility a fixed-stroke SAI cannot match. Because the 950mm stroke is lengthy, the 40mm rod handles high side loads, but an external guide is strongly recommended to prevent rod bending.
To replace an ISO 15552 cylinder, match the 200mm bore, 950mm stroke, 75mm adjustment, PT tapered port, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. If true load-holding is required without continuous air pressure, use an external rod lock or select an AirTAC SAIL or BSAI model, as this cylinder cannot hold position unpowered.
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 SAIJ200X950-75S FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 950mm nominal stroke anywhere within an 875-950mm travel window. It sets the end position but does not lock the load without live air pressure.
