About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-40
The AirTAC SAIJ32X175-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 135 to 175 mm, enabling precise end-position tuning at commissioning without external stops. It delivers a 0.5 MPa push force of 402 N and a pull force of 345 N.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-40 Is Used
Machine Changeover
Dial in the exact end position from 135 to 175 mm during product size changes without physically swapping the cylinder or adding external mechanical stops.
Assembly Calibration
Fine-tune the clamping or pressing position on the fly to accommodate material thickness variations, ensuring precise alignment using the 402 N force output.
Sensor Positioning
Utilize the dual-side sensor grooves to mount CMSE or DMSE switches alongside the adjustable rear stop for highly repeatable automated testing routines.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-40 the Right Cylinder?
Choose this 32 mm bore when you need the 402 N push force at 0.5 MPa and a mechanism to dial in the exact end-of-stroke within a 135-175 mm window. If your application requires less force, stepping down is not an option in this ISO series, but stepping up to a 40 mm bore yields 628 N push force. The adjustable stroke is ideal for machine setup and product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 175 mm nominal stroke, 40 mm adjustment range, PT port threads, and your required mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is under 300 mm, side-load risks are minimal, but ensure the M10x1.25 rod thread is properly aligned to avoid binding.

- ✓ 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 SAIJ32BX175-40 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 40 mm. This creates a usable travel window of 135 to 175 mm. It only sets the travel end and does not lock or hold the load without live air pressure.
At a 0.5 MPa operating pressure, the SAIJ32X175-40 provides a push force of 402 N and a pull force of 345 N. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf of push force.
