About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX950-20
The AirTAC SAIJ200X950-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring an external rear adjuster that permits a usable travel window of 930 to 950 mm. Delivering a substantial 28274N of push force at 0.9 MPa, it handles massive loads with precision. The piston rod is constructed from SUS304 stainless steel, offering superior corrosion resistance compared to standard carbon steel.
This adjustable-stroke model allows operators to fine-tune the retract end position during commissioning or product changeovers without swapping out the entire cylinder or adding external stops. It features a G3/4 PT tapered port and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic sensors if a magnet is added later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX950-20 Is Used
Heavy Press Tuning
Dial in the exact 930-950 mm retract position on a large metal stamping press during initial setup to accommodate varying material thicknesses.
Pallet Positioning
Adjust the end stop on a heavy-gauge pallet transfer line to accept different pallet lengths without physically replacing the actuator.
Large Assembly Jigs
Fine-tune the clamping reach on oversized assembly jigs where a 20 mm mechanical adjustment window saves hours of retooling time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX950-20 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme thrust, such as 28274N at 0.9 MPa, and a 950 mm stroke that needs precise mechanical trimming. If the force is excessive, stepping down to a 160 mm bore yields 18095N at 0.9 MPa. The rear adjustment screw is strictly a travel stop that decelerates the load; it does not hold the load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead.
Because this unit features a long 950 mm stroke, the 40 mm diameter rod and M36x2 thread will still experience deflection under heavy side loads. An external guide rail is strongly recommended to prevent rod binding and premature seal wear. This cylinder is dimensionally interchangeable per ISO 15552 and supports mountings from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200BX950-20 FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder generates 28274N of push force and 15080N of pull force. The maximum operating pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 950 mm nominal stroke by up to 20 mm, creating a 930-950 mm usable travel window. It only sets the travel end and does not lock the load without live air.
