About the Airtac SCJ32 Standard Cylinder SCJ32X175-75S
The SCJ32X175-75S is a double-acting, single-rod tie-rod cylinder that puts field-adjustable stroke control into a compact 32 mm bore package. Its rear-cap adjusting screw provides up to 75 mm of stroke-end reduction, letting you fine-tune the piston stop position from the full 175 mm nominal stroke down to 100 mm without changing the cylinder body. The 12 mm diameter piston rod and PT1/8 ports deliver a push force of 402 N at 0.5 MPa, rising to 724 N at the 0.9 MPa maximum operating pressure.
This model carries the -S magnet suffix, so a built-in magnetic piston ring lets you clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for non-contact end-of-stroke or mid-stroke position feedback. The standard TPU seals and PT threads keep it compatible with common filtered compressed-air systems, while the 21 mm air cushion at each end decelerates the piston quietly. The body length A(SCJ) is 182 mm, slightly longer than a fixed-stroke SC of the same bore to house the adjusting mechanism.
Airtac SCJ32 Standard Cylinder SCJ32X175-75S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X175-75S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 175 mm |
| Stroke adjustment | Up to 75 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke | Up to 1000 mm |
Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ32 Standard Cylinder SCJ32X175-75S Is Used
Commissioning & Setup
Dial in the exact stroke end position during machine commissioning without swapping cylinders or machining external hard stops. The 75 mm adjustment range covers a wide window for trial-and-error setup.
Small-Part Diverting
Adjust the push stroke on a diverter gate to match different package widths on a conveyor line. The built-in magnet allows position sensors to confirm the gate has fully extended and retracted.
Dispenser Depth Control
Fine-tune the dispense depth of a glue or paste applicator by adjusting the cylinder's rear stop. The 724 N push force at 0.9 MPa provides ample power for consistent material application.
Is the Airtac SCJ32 Standard Cylinder SCJ32X175-75S the Right Cylinder?
Choose the SCJ32 bore when your load needs up to 402 N of push force at standard plant pressure; if you require more force, the next step up is the 40 mm bore delivering 628 N at the same 0.5 MPa. This adjustable-stroke model is ideal where the end position must be dialled in during commissioning or changed for different product formats—if the stroke never needs field adjustment, a fixed-stroke SC32 cylinder is a simpler, lower-cost alternative. For exact replacement, match the 32 mm bore, 175 mm nominal stroke, 75 mm adjust range (-75), PT port thread, basic mounting, and the -S magnet option. At this 175 mm stroke, rod buckling is not a primary concern, but if the load applies a significant side force, add an external linear guide or consider a guided cylinder to protect the rod and bearing.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-75)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ32 Standard Cylinder SCJ32X175-75S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The push force is greater than the pull force because this is a single-rod cylinder.
A fixed-stroke SC32 will fit the same mounting and port connections, but you will lose the rear adjusting screw that allows field adjustment of the stroke end. If your application requires the ability to fine-tune the stroke position within a 75 mm range, you must replace it with another SCJ32X175-75S or an SCJ32 with an equivalent adjust range.
