Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 260mm 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 SAIJ100X260-100S
The AirTAC SAIJ100X260-100-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. Its built-in 100mm adjustment screw creates a 160-260mm usable travel window, allowing precise end-position tuning at commissioning without swapping the unit. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for solid-state DMSE or reed CMSE switches.
This model features a 25mm carbon steel piston rod with an M20x1.5 thread and a G1/2 port. The rear screw acts as a mechanical stop to trim the retract stroke, but it is not a load-holding lock. For applications requiring position maintenance without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100S Is Used
Variable Product Changeover
Dial in the 160-260mm travel window on the fly to accommodate different package sizes on a packaging line without physically replacing the cylinder.
End-Position Truing
Fine-tune the retract stop during machine commissioning to achieve exact pressing or clamping depths, eliminating the need for custom spacer shims.
Multi-Format Conveyor Diverter
Adjust the diverter arm reach precisely to handle varying pallet widths on a conveyor system, ensuring accurate routing without mechanical rebuilds.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100S the Right Cylinder?
Choose this 100mm bore when your application requires significantly more thrust than the 80mm bore (which provides 2513N at 0.5 MPa), but less than the heavy-duty 125mm class. The 100mm adjustment range is ideal for machines processing variable product sizes, replacing the need to bolt on external stops during changeovers. When specifying an ISO 15552 replacement, match the 100mm bore, 260mm nominal stroke, 100mm adjustment, G1/2 PT port, and -S magnet.
Because the nominal stroke is 260mm, ensure proper guiding to prevent excessive side-loading on the 25mm rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles. The standard variable air cushions at both ends help decelerate the load, operating effectively within the 30-800mm/s speed range.
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 SAIJ100X260-100S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 100mm, creating a 160-260mm usable travel window. It only sets the end position and does not lock the load without live air.
