About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-100
The AirTAC SAIJ160X225-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty automation. It features a SUS304 stainless steel rod and a PT tapered port thread. With a nominal 225 mm stroke and a 100 mm adjustment range, this model provides a usable travel window of 125 to 225 mm, allowing operators to dial in the exact retract position without external stops. At 0.5 MPa, it generates 10053 N of pull force and 14074 N of push force at 0.7 MPa, making it ideal for high-thrust applications.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The 40 mm diameter rod and M36x2 thread provide excellent rigidity, though long unsupported strokes still require an external guide. The rear adjuster acts purely as a mechanical stop to fine-tune the end position and must not be confused with a locking mechanism, as the cylinder cannot hold loads without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-100 Is Used
Heavy Press Fitments
Fine-tune the 125-225mm stroke window during setup to achieve precise pressing depths for large bearings without machining custom spacers.
Product Changeover
Rapidly adjust the retract end-stop on packaging lines when switching between different large-format product sizes.
Variable End Stops
Dial in the exact clamping position during machine commissioning to compensate for mechanical tolerances in heavy-duty assemblies.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-100 the Right Cylinder?
Choose this 160 mm bore when the 125 mm bore's 6136 N push force at 0.5 MPa is insufficient for your heavy-load handling. An adjustable stroke is highly advantageous over a fixed SAI cylinder during machine commissioning or product changeover, enabling a 125 to 225 mm variable end-stop window on the fly. If your process requires true load-holding without continuous air pressure, this cylinder is not suitable; instead, consider the SAIL air-released lock or BSAI clamp-lock series. For ISO 15552 dimensional interchangeability, match the 160 mm bore, 225 mm stroke, 100 mm adjustment, PT port, and mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ160 Adjustable Cylinder SAIJ160BX225-100 FAQ
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force at 0.7 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back from the 225 mm nominal stroke, creating a usable 125 to 225 mm window. It only sets the end position and does not lock the load without live air.
