About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-40
The AirTAC SAIJ160X950-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to trim the effective travel down from 950 mm to a minimum of 910 mm. This 40 mm adjustment window lets you dial in the exact retract end-position during commissioning without swapping the barrel or adding external stopper blocks. Delivering a substantial 14074 N of push force at 0.7 MPa, it is built for heavy-duty positioning.
This unit is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes dual sensor grooves on the extruded aluminum barrel. Because the rear screw acts purely as a travel stop and works alongside the standard air cushions, it does not lock the load without live air pressure. For applications requiring true load-holding, a SAIL or BSAI series cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-40 Is Used
Heavy Press Tuning
Fine-tune the retract distance on heavy presses to accommodate different material thicknesses without machining new external stops.
Product Changeover
Adjust the travel window from 910 to 950 mm on packaging lines to handle varying package sizes during rapid product transitions.
Assembly Line Setup
Dial in the exact end-position during initial machine commissioning to compensate for mechanical tolerance stack-up across long strokes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-40 the Right Cylinder?
Selecting this 160 mm bore model makes sense when your application requires the 10053 N pull force at 0.5 MPa and a highly specific end-stop. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N push at 0.5 MPa, while stepping up to a 200 mm bore provides 15708 N. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops to accommodate product changeovers on the same line. To match this exact configuration, specify a 160 mm bore, 950 mm stroke, 40 mm adjustment, PT tapered ports, SUS304 rod material, and no magnet. The mounting interface accepts Basic, FA, LB, TC, FTC, TCM1, or TCM2 brackets. Given the 950 mm stroke, an external guide is strongly recommended to prevent excessive side-loading on the rod.
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 SAIJ160BX950-40 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can deliver a maximum of 18095 N push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that can shorten the 950 mm nominal stroke by up to 40 mm, giving an effective travel window of 910 to 950 mm. It only sets the end-position and does not lock the load without continuous air pressure.
