About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX260-10S
The AirTAC SAIJ50X260-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 250 to 260 mm. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa. This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
By turning the rear stopper screw, you can fine-tune the retract end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. The adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX260-10S Is Used
Precision End-Stop Tuning
Dial in the exact retract position within a 250-260 mm window during machine commissioning without swapping out the entire actuator.
Product Size Changeover
Quickly adjust the stroke end by up to 10 mm on packaging lines when transitioning between different product dimensions.
Corrosive Assembly Stations
Leverage the SUS304 stainless steel rod for reliable actuation in environments requiring high corrosion resistance.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX260-10S the Right Cylinder?
Choose this 50 mm bore when an application requires around 982 N of push force at 0.5 MPa, or step up to a 63 mm bore if you need 1559 N. The 10 mm adjustable window is ideal for dialing in exact end positions during machine setup or product changeover, offering more flexibility than a fixed-stroke SAI cylinder. To match this ISO 15552 cylinder for a replacement, verify the 260 mm stroke, 10 mm adjustment, PT port threads, and the -S magnet option.
Because the 260 mm stroke creates a longer unsupported rod, ensure you use an external guide to prevent excessive side-loading. For any load-holding requirements without continuous air pressure, note that this cylinder's adjuster is not a lock; consider an AirTAC SAIL or BSAI model instead.
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 SAIJ50 Adjustable Cylinder SAIJ50BX260-10S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. It can reach a maximum push force of 1767 N at 0.9 MPa.
A rear stopper screw lets you mechanically shorten the nominal 260 mm stroke by up to 10 mm, creating a 250-260 mm usable travel window. This stopper only sets the end position and does not function as a lock.
