Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-40S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 475mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-40S
The AirTAC SAIJ100X475-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 435 to 475 mm. Delivering a robust 7068 N of push force at 0.9 MPa, it is designed for heavy-duty positioning. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for precise end-of-stroke detection using CMSE reed or DMSE electronic solid-state switches.
Configuration includes a carbon steel piston rod with an M20x1.5 thread and PT tapered ports. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock or hold the load without live air pressure. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-40S Is Used
Variable End-Stop Machining
Dial in the exact 435 to 475 mm clamping travel on machining fixtures to accommodate different part lengths without adding external stopper blocks.
Product Changeover Lines
Rapidly adjust the retract position during packaging size changeovers, using the rear screw to fine-tune the stroke for new carton dimensions.
Heavy-Duty Press Setup
Leverage the 7068 N push force for assembly presses, making precise end-position adjustments during initial machine commissioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X475-40S the Right Cylinder?
Choose this 100 mm bore when your application requires upward of 7068 N of push force at 0.9 MPa, or step down to an 80 mm bore if 4523 N is sufficient. An adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, providing fine-tuning at commissioning without swapping out a fixed-stroke SAI cylinder. Because the nominal stroke is 475 mm, an external guide is recommended to handle side loads and prevent rod deflection over this long travel distance.
For a true ISO 15552 replacement match, verify the 100 mm bore, 475 mm stroke, 40 mm adjustment range, PT port threads, and the -S magnet option. Remember that neither the rear adjuster nor the air cushions function as a lock; if you need fail-safe load holding without live air, consider the SAIL pneumatic lock or BSAI clamp-lock series.
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 SAIJ100X475-40S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides 7068 N of push force and 3681 N of pull force. At 0.5 MPa, it delivers 3927 N push and 3681 N pull.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 40 mm, providing a usable travel window of 435 to 475 mm. It only sets the travel end and does not lock the load without live air pressure.
