About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX475-75
The AirTAC SAIJ50X475-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 400 to 475 mm. Delivering 982 N of push force at 0.5 MPa, it bridges the gap between mid-size and heavy industrial pneumatic actuation. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning of CMSE reed or DMSE electronic switches.
This specific SKU features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and uses PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning, and it does not function as a lock to hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX475-75 Is Used
Product Changeover
Quickly adjust the end-stop from 475 mm down to 400 mm when a production line switches to a different package size, eliminating the need to physically swap cylinders.
Commissioning Fine-Tune
Dial in the exact retract position during machine setup to perfectly seat a 982 N press force without machining custom external spacers.
Variable End-Stop Routing
Provide a adjustable physical stop for diverter arms on a conveyor, allowing the travel distance to be modified on the fly for varying product lengths.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX475-75 the Right Cylinder?
Choose this 50 mm bore when your application requires the 982 N push force at 0.5 MPa, stepping up from a 40 mm bore that provides 628 N, or down from a 63 mm bore offering 1559 N. The 75 mm adjustable range is ideal for product changeovers on a line, allowing you to dial back the 475 mm nominal stroke without adding external stops or swapping out a fixed-stroke SAI cylinder.
Because the 475 mm stroke is relatively long, an external guide is recommended to manage side loads on the 20 mm rod. When specifying an ISO 15552 replacement, match the 50 mm bore, 475 mm stroke, 75 mm adjustment, PT G1/4 port, and your required mounting option from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. For applications requiring true load-holding without air pressure, consider the SAIL or BSAI series 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 SAIJ50AX475-75 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At the maximum 1.0 MPa pressure, it can deliver up to 200 kgf.
The rear adjuster screw lets you mechanically shorten the effective stroke from its 475 mm nominal length down to 400 mm. It functions as a travel stop for end-position tuning and does not lock the load without continuous air pressure.
