About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-20
The AirTAC SAIJ32X160-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 160 mm travel back by up to 20 mm, creating a precise 140-160 mm usable window. It delivers 402 N of push force at 0.5 MPa and uses a PT tapered port with a G1/8 thread size. The piston rod is constructed from SUS304 stainless steel for superior corrosion resistance.
This adjustable model lets you fine-tune end positions at commissioning or during product changeover without swapping the cylinder or bolting on external stops. It includes adjustable air cushions at both ends and features sensor grooves on both sides of the extruded aluminum barrel. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-20 Is Used
Machine Commissioning
Dial in the exact 140-160 mm end position during setup without adding external stopper blocks.
Product Changeover
Quickly adjust the retract stop to accommodate different product sizes on the same line.
Positioning Stops
Fine-tune the travel end for delicate pick-and-place operations requiring precise endpoints.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-20 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and a variable end-stop within a 140-160 mm window. If your machine needs higher force, stepping up to the 40 mm bore yields 628 N of push force. Conversely, if you need less force, you would drop down to a smaller size. The adjustable stroke is ideal for machine setup where you need to dial in the exact end position without ordering a custom fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 160 mm nominal stroke, 20 mm adjustment range, PT port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the 160 mm stroke is relatively short, side-loading is less of a concern, but you should still ensure the load is guided to prevent rod damage. For load-holding without live air pressure, consider the SAIL or BSAI series instead.
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 Adjustable Cylinder SAIJ32 SAIJ32BX160-20 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm from the nominal 160 mm, giving you a usable travel window of 140-160 mm. It acts as a mechanical stop and does not lock the load without air pressure.
