About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-10S
The AirTAC SAIJ100X260-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for demanding setups. It features a 100mm bore and a 260mm nominal stroke that can be precisely dialed back by up to 10mm, creating a 250-260mm usable travel window for exact end-position tuning. With a carbon steel piston rod and PT tapered port threads, it provides reliable operation, while the integrated magnet enables compatibility with CMSE reed and DMSE electronic sensors for accurate position feedback.
This model generates a substantial 7068N of push force at 0.9 MPa and includes variable air cushions at both ends to manage deceleration. The extruded aluminum barrel utilizes standard ISO 15552 mounting interface dimensions, ensuring seamless interchangeability with comparable profile cylinders. The rear adjuster acts purely as a mechanical stop to trim the stroke and cannot hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-10S Is Used
Precision End-Stop Tuning
Dial in the exact 250-260mm travel window during machine commissioning to perfect part seating or forming depth without mechanical rework.
Product Changeover
Quickly adjust the rear stopper by up to 10mm on automated lines when switching between slightly different product sizes or thicknesses.
Heavy Assembly Press
Leverage the 7068N push force at 0.9 MPa to drive heavy-duty joining operations, using the adjustable stroke to accommodate varying material stacks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-10S the Right Cylinder?
Selecting the SAIJ100X260-10-S is ideal when an application requires fine end-position tuning during commissioning or product changeover without the need to physically swap cylinders or bolt on external stops. If your process demands less force, stepping down to an 80mm bore yields 4523N of push force at 0.9 MPa; conversely, moving up to a 125mm bore provides 11045N for heavier loads. Since the 260mm stroke exceeds the 300mm threshold, external guiding is recommended to prevent excessive side-loading on the rod and thread.
Because this is an adjustable-stroke variant, the 10mm rear stopper allows you to shorten the effective travel as needed, whereas a fixed SAI cylinder locks you into a single exact dimension. For any load-holding requirements without continuous live air, note that neither the rear adjuster nor the air cushions function as a lock; you should explore an AirTAC SAIL or BSAI cylinder instead. To match this exact ISO 15552 replacement, specify the 100mm bore, 260mm stroke, 10mm adjustment, PT port, and the -S magnet option.
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 SAIJ100X260-10S FAQ
At 0.9 MPa, this 100mm bore cylinder provides 7068N of push force and 3681N of pull force. It operates at a speed range of 30-800 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the 260mm nominal stroke by up to 10mm, creating a 250-260mm usable travel window. It only sets the travel end and does not lock or hold the load without live air pressure.
