About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX65-10
The AirTAC SAIJ50X65-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 55 to 65 mm. Delivering 982 N of push thrust and 825 N of pull force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and is equipped with PT tapered port threads.
Because the adjuster acts purely as a mechanical stop at the retract end, it cannot hold a load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches later if position detection is required.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX65-10 Is Used
Machine Changeover
Dial in the 55-65 mm travel window during product size transitions to set exact retract positions without swapping hardware.
End-Stop Tuning
Use the 10 mm rear adjustment range to precisely set the retract end-position during initial machine commissioning.
Washdown Handling
The SUS304 stainless steel rod handles positioning tasks in environments where standard carbon steel rods might corrode.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX65-10 the Right Cylinder?
Choose this 50 mm bore when your application needs the 982 N thrust at 0.5 MPa, stepping up from a 40 mm bore that provides 628 N. The 10 mm adjustable range is ideal for fine-tuning the end position during machine commissioning or product changeover without adding external stops or replacing a fixed-stroke SAI cylinder.
For any load-holding requirements without continuous air pressure, this cylinder is insufficient as the rear screw is not a lock; you should specify an SAIL or BSAI model instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ50BX65-10 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
The rear adjuster allows you to shorten the 65 mm nominal stroke by up to 10 mm, providing a usable travel window of 55 to 65 mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
