About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10
The AirTAC SAIJ100X650-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 100 mm bore and a 650 mm stroke, yielding a usable travel window of 640 to 650 mm. Delivering 7068 N of push force at 0.9 MPa, it handles heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This model uses a 25 mm carbon steel rod with an M20x1.5 thread, providing robust resistance against side loads. The rear stopper screw allows precise end-position tuning at commissioning without swapping the cylinder. Remember that this adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10 Is Used
Press Stroke Tuning
Dial in the exact 640 to 650 mm end position during machine setup to accommodate varying material thicknesses without adding external stops.
Product Changeover
Quickly adjust the retract distance on packaging lines when switching to different box sizes, using the rear screw for rapid mechanical resets.
Heavy Load Positioning
Leverage the 7068 N push force to move heavy pallets or fixtures, relying on the 25 mm rod to maintain stability under dynamic loads.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10 the Right Cylinder?
Choose this 100 mm bore cylinder when an 80 mm bore (providing 4523 N push at 0.9 MPa) is insufficient for your load. The 10 mm adjustment window is ideal for fine-tuning the retract end during product changeovers instead of installing external stops. If your process requires holding a load without live air, select the SAIL (pneumatic lock) or BSAI (clamp-lock) series instead of relying on the adjuster.
For an exact ISO 15552 interchangeability match, verify the 650 mm stroke, 10 mm adjustment range, PT tapered port (G1/2), and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 650 mm, an external guide is recommended to prevent rod sag and premature seal wear.
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 SAIJ100X650-10 FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 3681 N of pull force. It can reach a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 650 mm nominal stroke by up to 10 mm, creating a 640 to 650 mm travel window. This stopper only sets the end position and does not lock the load without continuous air pressure.
