About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-30
The AirTAC SAIJ160X850-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 820 to 850 mm. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 18095N push force at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors.
This adjustable variant lets you fine-tune the retract end-position during commissioning without swapping hardware. The rear screw acts purely as a travel stop and does not hold the load without live air; for position holding, consider SAIL or BSAI cylinders. With an 850 mm stroke, the 40 mm rod diameter requires an external guide to prevent excessive side-loading.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-30 Is Used
Long-Stroke Positioning
Dial in the exact 820 to 850 mm retract distance for heavy product handling without adding external mechanical stops.
Line Changeover
Quickly adjust the end-stop to accommodate different large frame sizes during production line transitions.
Heavy Assembly Press
Fine-tune the working stroke on heavy fixtures, relying on the 18095N thrust for robust pressing action.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-30 the Right Cylinder?
Stepping down to the 125 mm bore reduces push force to 11045N at 0.9 MPa, whereas the 160 mm bore provides 18095N for heavy-duty tasks. Choose this adjustable-stroke model over a fixed SAI when you need variable end-stops for product changeovers. It is dimensionally interchangeable with ISO 15552 cylinders and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Because the stroke is 850 mm, always use an external guide to manage side loads.

- ✓ 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 SAIJ160BX850-30 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N.
The rear adjuster screw trims the nominal 850 mm stroke back by up to 30 mm, providing an effective travel window of 820 to 850 mm for fine-tuning at commissioning.
