About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX500-50
The AirTAC SAIJ50X500-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 450-500mm usable travel window. Delivering 982N of push thrust at 0.5 MPa, it handles robust linear motion. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear mechanical stopper allows precise end-position tuning during commissioning without adding external stops. Remember the adjuster only sets the travel end; it does not function as a lock to hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX500-50 Is Used
Machine Setup Tuning
Dial in the exact 450-500mm end-stop during initial machine commissioning to perfectly position a large workpiece without machining custom spacers.
Product Changeover
Quickly adjust the stroke length on a packaging line when switching to a different box size, saving minutes of reconfiguration time per shift.
Variable End Stops
Set precise retraction points for automated assembly presses, allowing operators to tweak the travel limit as tooling wear occurs over time.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX500-50 the Right Cylinder?
Select this 50mm bore cylinder when an application requires 982N push force at 0.5 MPa and exact end-position dialing. The 50mm adjustment range is ideal for product changeovers. If your setup needs less force, the 40mm bore provides 628N. For higher loads, the 63mm bore yields 1559N. Because the 500mm stroke is long, an external guide is recommended to prevent excessive side loading on the rod.
This model is dimensionally interchangeable per ISO 15552. To match this replacement exactly, verify the 50mm bore, 500mm stroke, 50mm adjustment range, PT G1/4 port, and the SUS304 rod material. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without live pressure, consider an AirTAC SAIL or BSAI cylinder 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 SAIJ50BX500-50 FAQ
At 0.5 MPa operating pressure, this 50mm bore cylinder provides 982N of push thrust and 825N of pull thrust. At the maximum 1.0 MPa pressure, it can deliver up to 200 kgf.
The rear adjuster screw acts as a mechanical stop, letting you shorten the 500mm nominal stroke by up to 50mm, creating a 450-500mm travel window. It only sets the end position and does not lock the load without live air.
