Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-40S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 500mm 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 SAIJ100X500-40S
The AirTAC SAIJ100X500-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927N of push force at 0.5 MPa and provides a usable travel window of 460 to 500 mm, allowing you to trim the effective stroke by up to 40 mm without adding external stops. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for CMSE reed and DMSE electronic switches.
This model uses a G1/2 port and a 25mm carbon steel rod with an M20x1.5 thread. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-40S Is Used
Product Changeover
Dial in the exact 460-500mm retract distance during product size changes without physically replacing the cylinder or adding external stopper blocks.
Machine Setup
Fine-tune the end-of-stroke position during commissioning to perfect a pressing or lifting operation, absorbing mechanical tolerance variations.
Variable End Stops
Adjust the travel end on a conveyor diverting arm to handle different package sizes, using the 40mm adjustment range to alter the rest position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-40S the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (2513N at 0.5 MPa) lacks thrust or a 125mm bore is too bulky. The adjustable 460-500mm travel window is ideal for product changeovers on a line, letting you dial in the exact retract distance on the fly rather than swapping a fixed-stroke SAI cylinder. To replace an ISO 15552 unit, match the 100mm bore, 500mm stroke, 40mm adjustment, G1/2 PT ports, and -S magnet.
Because the 500mm stroke is long, the unsupported 25mm rod is susceptible to side-loading; always use an external guide rail to prevent premature seal wear. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ100X500-40S FAQ
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. At 0.7 MPa the push force increases to 5497N.
A rear screw acts as a mechanical stop, allowing you to shorten the nominal 500mm stroke by up to 40mm, creating a 460-500mm adjustable travel window. It only sets the end position and does not lock the load without live air.
