About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-100S
The AirTAC SAIJ200X1000-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 28274N push force at 0.9 MPa and features a 1000mm nominal stroke that can be fine-tuned down by up to 100mm, yielding a 900-1000mm usable travel window. This adjustability allows precise end-position calibration at commissioning without adding external stops.
This specific SKU includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet (-S) for compatibility with AirTAC CMSE reed and DMSE electronic sensors. Fluid ports are PT tapered threads. With a 1000mm stroke, the 25mm rod and M20x1.5 thread provide structural support, but an external guide is highly recommended to manage side loads over this long unsupported travel distance.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 900-1000mm end position during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover Diverter
Adjust the stroke by up to 100mm on a conveyor diverter to handle different package sizes on the fly without repositioning hardware.
Large Assembly Fixture
Utilize the 28274N force and SUS304 rod in large-scale assembly fixtures requiring precise, variable end-stops and reliable position feedback.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-100S the Right Cylinder?
Choose this 200mm bore model when an application requires maximum thrust up to 3204 kgf at 1.0 MPa combined with variable end stops. If you need less force, stepping down to a 160mm bore yields 18095N push at 0.5 MPa, but the 200mm bore is necessary for heavy-duty pressing. The adjustable stroke is ideal for machine setups requiring product-size changeovers, whereas a fixed SAI cylinder is preferred if the end stop never changes.
For any stroke length of 1000mm, side-load management is critical; use external guides to prevent rod binding. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air. For true load-holding without continuous pressure, consider the SAIL pneumatic lock or BSAI clamp-lock series instead of relying on the adjuster.
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 SAIJ200BX1000-100S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 100mm, providing a 900-1000mm usable travel window. It only sets the end position and deceleration; it does not lock the load without live air pressure.
At 0.9 MPa, the push force is 28274N and the pull force is 25133N. The maximum operating speed is 30-500 mm/s, and it uses G3/4 fluid ports.
