About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-50S
The AirTAC SAIJ200X200-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 21991N push force at 0.7 MPa, making it suited for heavy-duty positioning. The integrated adjuster allows you to fine-tune the retract end-of-travel, creating a 950-1000 mm usable window from its 1000 mm nominal stroke.
This non-standard 1000 mm configuration is engineered for long-trroke applications. It features a SUS420J2 stainless steel rod and a PT tapered port. The extruded aluminum barrel includes dual sensor grooves, and the integrated magnet enables precise position detection with AirTAC CMSE reed and DMSE electronic switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-50S Is Used
Long-Stroke Positioning
Dial in the exact 950-1000mm retract position for large format material handling without swapping the cylinder.
Commissioning Calibration
Fine-tune the end stop during machine setup to perfect heavy-load placement at 0.7 MPa operating pressure.
Product Changeover
Quickly adjust the travel end-point on automated lines when processing different oversized product dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-50S the Right Cylinder?
Selecting this 200 mm bore size is appropriate when your application requires moving heavy payloads that exceed the 14074N push force of a 160 mm bore at 0.7 MPa. The 50 mm adjustment range is ideal for dialing in exact end positions during machine commissioning or product changeover without adding external stops. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB and CA options.
Because the 1000 mm stroke is non-standard and long, you must account for rod sag and side loads; an external guide is strongly recommended to prevent premature wear. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air. For fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ200AX1000-50S FAQ
At 0.7 MPa, this 200 mm bore cylinder provides 21991N of push force and 21991N of pull force. It can deliver a maximum push force of 28274N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 50 mm. This creates a usable travel window between 950 mm and 1000 mm for precise end-position tuning.
