About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-50S
The AirTAC SAIJ32X180-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 130 to 180 mm, allowing you to dial back the nominal 180 mm stroke by up to 50 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This SKU features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing. The barrel utilizes an extruded aluminum profile with sensor grooves on both sides, accommodating AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid ports are PT (tapered) G1/8, and the unit reaches speeds of 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-50S Is Used
Product Changeover
Dial in the exact 130 to 180 mm retract distance on packaging lines when switching to a different product size.
Commissioning Fine-Tune
Trim the end-of-stroke position during initial setup without machining hard stops or disassembling the fixture.
Light-Duty Positioning
Apply 402 N of push force to index small actuators or gates in semi-automated assembly machinery.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-50S the Right Cylinder?
Choose this 32 mm bore when 402 N of push force at 0.5 MPa is sufficient for your load; step up to the 40 mm bore if you need 628 N to overcome higher friction or payload. An adjustable stroke is selected over a fixed SAI when you need a variable end-stop to fine-tune the retract position on product changeovers without swapping cylinders or adding external stops. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-stop holding, use a SAIL or BSAI cylinder. When replacing an ISO 15552 unit, match the 32 mm bore, 180 mm stroke, 50 mm adjuster, PT G1/8 ports, and the -S magnet. Because the 180 mm stroke is substantial for a 32 mm bore, ensure an external guide supports the load to prevent rod side-loading.

- ✓ 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 SAIJ32BX180-50S FAQ
The rear adjuster screw lets you shorten the effective travel from 180 mm down to 130 mm. It acts as a mechanical stop to set the retract position, but it does not lock or hold the load without continuous air pressure.
At 0.5 MPa it provides 402 N push and 345 N pull force. The -S option includes a magnet for use with AirTAC CMSE reed and DMSE electronic sensors mounted in the dual-side barrel grooves.
