About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-40
The AirTAC SAIJ100X650-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 650 mm travel by up to 40 mm. This yields a precise 610-650 mm usable end-position window, perfect for fine-tuning machinery during commissioning or product changeovers without adding bulky external stops. It delivers robust thrust, pushing 7068 N at 0.9 MPa, to handle heavy loads with confidence.
This SKU features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and carries a G1/2 PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this specific configuration ships without a magnet. The rear adjuster acts strictly as a travel stop to set deceleration alongside the standard air cushions; it is not a locking device and will not hold a load without live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-40 Is Used
Product Size Changeovers
Quickly reconfigure the 610-650 mm travel window on packaging lines when switching between different pallet or container sizes without swapping hardware.
Machine Commissioning
Fine-tune the exact end-of-stroke position during initial setup to dial in precise mechanical stops for heavy 7068 N press operations.
Variable End Stops
Adapt automated assembly stations on the fly by trimming the rear travel stop up to 40 mm to accommodate multi-stage forming processes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-40 the Right Cylinder?
Choose this 100 mm bore when you need substantial push force (7068 N at 0.9 MPa) over a long 650 mm stroke that requires exact end-position tuning. If your application requires less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, whereas moving up to a 125 mm bore provides 11045 N. The adjustable 610-650 mm window is ideal for variable product sizes on a line, whereas a fixed SAI cylinder is better suited for static, unchanging end stops.
Because the 650 mm stroke is long, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading and rod bending. To replace an ISO 15552 cylinder, match the 100 mm bore, 650 mm stroke, 40 mm adjustment, G1/2 PT port, and your required mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. If true load-holding without live air is required, consider the SAIL or BSAI variants instead of relying on the adjuster.

- ✓ 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 SAIJ100AX650-40 FAQ
It can deliver a maximum push force of 801 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 650 mm down to 610 mm. This stopper fine-tunes the end position and deceleration point but does not lock the load without continuous air pressure.
