About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-10S
The AirTAC SAIJ32X145-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 135 to 145 mm. Fitted with a SUS304 stainless steel rod and a -S magnet, it integrates seamlessly with CMSE reed and DMSE electronic sensors housed within the dual-side extruded barrel grooves. Delivering 402N of push force at 0.5 MPa, it handles lighter-duty positioning tasks effectively.
Unlike a fixed-stroke SAI cylinder, this model features an external adjusting screw at the rear that acts purely as a travel stop to fine-tune the retract end-position during commissioning. It utilizes a PT tapered G1/8 port and variable air cushions at both ends to decelerate the load, but it does not function as a lock or brake. For applications requiring true position holding without live air pressure, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-10S Is Used
Variable End-Stop Tuning
Fine-tune the 135-145 mm retract position during machine commissioning to accommodate minor sensor or fixture offsets without replacing hardware.
Product Changeover
Rapidly adjust the effective stroke by up to 10 mm when switching between slightly different product sizes on the same conveyor line.
Light-Force Positioning
Utilize the 402N push force at 0.5 MPa for delicate handling tasks requiring repeatable end-of-travel placement accuracy.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-10S the Right Cylinder?
Selecting this 32mm bore over a 40mm neighbor (which yields 628N at 0.5 MPa) is ideal when your application requires precise, lighter-force positioning rather than heavy thrust. The adjustable 10mm end-stop allows you to dial in the exact 135-145mm travel window on the fly, avoiding the need to swap out the entire cylinder or bolt on external stops during product changeovers.
When replacing an ISO 15552 cylinder, ensure you match the 145mm stroke, 10mm adjustment range, PT G1/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the 12mm rod and M10x1.25 thread carry limited side-load capacity, always guide the load externally to prevent binding.
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 SAIJ32BX145-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum of 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the nominal 145mm stroke by up to 10mm, creating a usable travel window of 135 to 145mm. It only sets the travel end and does not lock or hold the load without live air pressure.
