Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-75S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-75S 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 SAIJ100X260-75S
The AirTAC SAIJ100X260-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 260 mm stroke that can be fine-tuned backward by up to 75 mm, yielding a usable travel window of 185 to 260 mm. Belonging to the 100 mm bore class, it delivers substantial thrust—generating 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa.
This model features a carbon steel piston rod and PT tapered port threads (G1/2). The -S suffix denotes an integrated magnet for position sensing, designed to work seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to set the end position and relies on the variable air cushions for deceleration; it does not lock the load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-75S Is Used
Product Size Changeovers
Dial in the 185 to 260 mm stroke window on the fly to accommodate different product lengths on a packaging line without changing out the cylinder.
Commissioning Fine-Tuning
Use the 75 mm rear adjustment screw to perfectly set the retract end-position during machine setup, avoiding the need for external shims or spacers.
Heavy Material Handling
Leverage the 7068 N push force at 0.9 MPa to move heavy pallets or workpieces, relying on the built-in air cushions to decelerate the load smoothly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-75S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires heavy thrust combined with variable end-stop positioning. If 7068 N at 0.9 MPa is excessive, stepping down to an 80 mm bore reduces the push force to 4523 N, whereas moving up to a 125 mm bore increases it to 11045 N. The adjustable 185 to 260 mm travel window is ideal for product-size changeovers on a line, eliminating the need to physically swap cylinders or bolt on external stops during commissioning.
Because the stroke is 260 mm, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading on the piston. For dimensionally interchangeable per ISO 15552 mounting interface replacements, match the 100 mm bore, 260 mm stroke, 75 mm adjustment, G1/2 PT port, and -S magnet. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the SAIJ adjuster is a travel stop, not a brake; for true load-holding without live air, consider the SAIL or BSAI variants.
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 SAIJ100X260-75S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear mechanical stopper allows you to trim the effective travel from the 260 mm nominal stroke down to a minimum of 185 mm. It sets the physical end position but does not hold the load without live air pressure.
