About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-10
The AirTAC SAIJ100X900-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 3927N push force at 0.5 MPa, with a 900mm nominal stroke that can be precisely dialed back by up to 10mm to achieve an exact 890-900mm travel window.
Equipped with a robust 25mm carbon steel rod and an M20x1.5 thread, it handles high side loads effectively, though an external guide is recommended for this 900mm length. The extruded aluminum barrel includes dual sensor grooves for CMSE reed or DMSE solid-state switches, while the mounting set supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-10 Is Used
Machine Changeover
Dial in the exact retract position within the 890-900mm window during product size transitions without installing external physical stops.
Assembly Presses
Leverage the 3927N push force at 0.5 MPa for heavy pressing tasks while using the rear screw to set precise end-of-stroke limits.
Conveyor Diverter Setup
Fine-tune the actuation endpoint on long-stroke material handling lines to perfectly sync with varying product dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-10 the Right Cylinder?
Choose this 100mm bore when an 80mm bore (2513N push at 0.5 MPa) is insufficient for moving heavy assemblies, but a 125mm bore (6136N) would be excessive and waste air volume. The 10mm rear adjustment screw is ideal for fine-tuning the retract end position during commissioning or product changeovers without swapping the cylinder or adding external stops.
For a 900mm stroke, supporting the rod with an external guide prevents premature wear. Note that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither holds the load without live air. For true load-holding, use an external rod lock or explore the SAIL or BSAI cylinder series. This unit uses PT tapered ports.
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 SAIJ100 Adjustable Cylinder SAIJ100X900-10 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm, creating a usable travel window of 890-900mm. This stopper only sets the end position and does not lock or hold the load without continuous air pressure.
