About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX75-10
The AirTAC SAIJ50X75-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 65 to 75 mm, enabling precise end-position tuning during commissioning without external stops.
Delivering 982 N of push force at 0.5 MPa, this bore size handles robust actuation tasks. The piston rod utilizes SUS304 stainless steel for superior corrosion resistance, and the extruded aluminum barrel includes dual-side sensor grooves for flexible switch mounting.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX75-10 Is Used
Machine Setup Tuning
Dial in the exact 65 to 75 mm retract position during initial commissioning to perfect end-of-stroke alignments without machining external stopper blocks.
Product Size Changeover
Quickly adapt the stroke window on packaging lines handling varying product lengths by turning the rear adjuster screw during format changes.
Clamping Force Control
Regulate the precise travel limit on clamping fixtures to prevent workpiece deformation, relying on the 982 N thrust at 0.5 MPa operating pressure.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX75-10 the Right Cylinder?
Choose this 50 mm bore when a 40 mm cylinder (628 N at 0.5 MPa) lacks thrust or a 63 mm bore (1559 N) is oversized. The 10 mm adjustment range is ideal for product changeovers, allowing you to fine-tune the retract end without swapping the cylinder. The rear adjuster acts as a travel stop, not a lock; for load-holding without live air pressure, consider the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 50 mm bore, 75 mm stroke, PT G1/4 port, and mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ50BX75-10 FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. At the maximum 1.0 MPa pressure, it provides up to 200 kgf.
The rear adjuster screw allows you to shorten the 75 mm nominal stroke by up to 10 mm, creating a 65 to 75 mm usable travel window. This stopper sets the end position but does not lock the load without live air.
