About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-100
The AirTAC SAIJ100X260-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 160 to 260 mm, allowing you to dial back the nominal 260 mm stroke by up to 100 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and PT tapered port threads for robust, corrosion-resistant performance.
Unlike a fixed-stroke SAI cylinder, this model lets you fine-tune the retract end position without swapping the barrel or adding external stops. The extruded aluminum profile includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches, though this specific SKU is supplied without a magnet. Remember that the rear adjuster acts purely as a travel stop, not a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-100 Is Used
Product Changeover
Dial the stroke back by up to 100 mm to accommodate different package sizes on the same line without physically replacing the cylinder.
End-Position Tuning
Fine-tune the retract stop during commissioning to dial in exact 160 to 260 mm travel distances for precision assembly tasks.
Variable End Stops
Set distinct retract positions for multi-stage forming or pressing operations using the rear adjustment screw rather than external hard stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-100 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust—stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while moving up to 125 mm yields 6136 N. The 100 mm adjustment range is ideal for machinery handling multiple product sizes, enabling rapid changeover without mechanical rebuilds. To replace an existing ISO 15552 cylinder, match the 100 mm bore, 260 mm stroke, 100 mm adjuster, PT G1/2 port, and preferred mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (FB, CA, CB, and CR are omitted).
Because the total stroke reaches 260 mm, the 25 mm rod and M20x1.5 thread should be supported by an external guide to prevent excessive side-loading on the piston. If your process requires the load to be held mechanically without live air pressure, this standard SAIJ adjuster will not suffice; instead, specify an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock.

- ✓ 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 SAIJ100BX260-100 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 801 kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 260 mm down to as little as 160 mm. This allows rapid end-position tuning without changing the cylinder or adding external stops.
