About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX160-10
The AirTAC SAIJ50X160-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 150-160 mm usable travel window, allowing you to dial back the 160 mm nominal stroke by up to 10 mm during commissioning. This fine-tuning capability eliminates the need to swap cylinders or bolt on external stops when aligning end positions.
In the 50 mm bore class, it generates 982 N of push force and 825 N of pull force at 0.5 MPa. The piston rod is built from SUS304 stainless steel for superior corrosion resistance, and the extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-800 mm/s and uses PT tapered port threads.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX160-10 Is Used
Machine Changeover
Dial in the 150-160 mm travel window during product size changes without swapping out the entire cylinder or reworking fixed external stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to precisely align tooling hits, using the 10 mm rear adjustment screw to absorb mechanical tolerances.
Assembly Station Setup
Set variable end stops for pressing or clamping operations where the exact 160 mm stroke needs slight real-world adjustment to hit the target depth.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX160-10 the Right Cylinder?
Choose this 50 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning on a 160 mm travel window, stepping up from a 40 mm bore that yields 628 N push force at 0.5 MPa. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead. Because the stroke is under 300 mm, side-load risks are minimal, though long unsupported loads still require an external guide.
When replacing an ISO 15552 cylinder, match the 50 mm bore, 160 mm stroke, 10 mm adjustment range, PT G1/4 port, and your required mounting bracket. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, intentionally omitting FB, CA, CB, and CR options. As no magnet is specified, this configuration does not support position sensing without modification.

- ✓ 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 SAIJ50BX160-10 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 the maximum pressure of 1.0 MPa, it can deliver up to 200 kgf.
The rear adjuster screw lets you shorten the 160 mm nominal stroke by up to 10 mm, creating a 150-160 mm usable travel window. The adjuster functions as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
