About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-50
The AirTAC SAIJ160X300-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This creates a highly versatile 250-300 mm usable stroke window, letting you fine-tune the retract end position during commissioning without swapping out the barrel or adding bulky external stops. Built for heavy-duty tasks, it delivers a robust 18095 N of push force at 0.9 MPa and utilizes a sturdy 40 mm diameter piston rod to handle significant side loads.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward positioning feedback. It is important to note that the rear adjuster functions strictly as a travel stop to set deceleration and end-position, not as a locking device; the cylinder cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-50 Is Used
Heavy-Duty Product Changeover
Dial in the 250-300 mm travel window during production line changeovers to accommodate different large-component sizes without physically swapping cylinders.
Press Fit Commissioning
Fine-tune the exact end-position for heavy press-fitting tasks, using the rear stopper to set precise depths under the 18095 N push force.
Large Assembly Jigs
Provide adaptable actuation on large assembly jigs where the 40 mm SUS304 rod withstands harsh environments and handles substantial side-loading.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-50 the Right Cylinder?
Selecting this 160 mm bore model is ideal when your application requires the 18095 N push force at 0.9 MPa and a highly specific retract distance within the 250-300 mm window. If your setup requires less force, stepping down to a 125 mm bore yields 11045 N at 0.9 MPa, whereas moving up to a 200 mm bore provides a massive 28274 N. Because the stroke is 300 mm, the extended unsupported rod length means an external guide rail is strongly recommended to prevent binding and excessive wear under heavy loads.
An adjustable-stroke cylinder is chosen over a fixed-stroke SAI when a machine requires variable end-stops for rapid product changeovers or fine-tuning at setup. When matching this for an ISO 15552 replacement, verify the 160 mm bore, 300 mm nominal stroke, 50 mm adjustment range, PT G3/4 ports, and the appropriate mounting option from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. Since no magnet is specified, position sensing via CMSE or DMSE switches is not enabled out of the box.
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 SAIJ160 Adjustable Cylinder SAIJ160BX300-50 FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. It can deliver a maximum force of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 300 mm stroke by up to 50 mm, providing a usable travel window of 250-300 mm. It only sets the end position and deceleration; it does not lock or hold the load without live air pressure.
