About the Airtac SCJ32 Standard Cylinder SCJ32X175-100S
The SCJ32X175-100S is a 32 mm bore double-acting single-rod cylinder that puts field-adjustable stroke control directly on the machine. Its rear-cap adjusting screw lets you shorten the stroke end by up to 100 mm without removing the cylinder, making it ideal for commissioning trials and format changes on compact automation. At 0.5 MPa it delivers 402 N push and 345 N pull, with a 12 mm rod and PT1/8 ports.
This model includes a built-in magnet (-S suffix), so CMSG/DMSG/EMSG reed and solid-state sensors clamp straight onto the tie-rod barrel for reliable end-of-stroke detection. The 21 mm air cushion decelerates the piston quietly, and the standard TPU seal works from -20 to +70 °C. Body length A is 182 mm plus stroke, giving a tidy envelope for light feeding, sorting, and clamping stations.
Airtac SCJ32 Standard Cylinder SCJ32X175-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X175-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 175 mm |
| Stroke adjustment | Up to 100 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 SCJ32X175-100S Is Used
Commissioning & Setup
Fine-tune the stroke end during machine bring-up without swapping cylinders. The 100 mm adjustment range lets technicians dial in the exact stopping position for grippers or pushers on the fly.
Small-Part Sorting Gates
Adjust the gate opening stroke to handle different product sizes on a conveyor. The built-in magnet provides clean sensor signals to the PLC for high-speed diverting and counting.
Wear Take-Up on Clamps
Compensate for jaw or pad wear in light-duty clamping fixtures by simply turning the rear screw. This keeps clamping force consistent without reprogramming the machine or adding shims.
Is the Airtac SCJ32 Standard Cylinder SCJ32X175-100S the Right Cylinder?
Choose the SCJ32 when you need a compact adjustable-stroke cylinder in the 402 N push class. If your load grows, stepping up to the SCJ40 provides 628 N push at the same 0.5 MPa pressure, while still keeping the same PT1/8 port size. For applications that don't require field adjustment, the fixed-stroke SC32 is a simpler, lower-cost alternative.
To replace this unit, match a genuine AirTAC SCJ32 with a 175 mm nominal stroke, -100 adjust range, PT thread, and the -S magnet option. For strokes of 300 mm or more, consider an external guide rail or a guided cylinder to protect the 12 mm rod from side-load bending in fully extended positions.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ32X175-100S FAQ
At 0.5 MPa air pressure the cylinder produces 402 N pushing force and 345 N pulling force (the pull is lower because of the single 12 mm rod area). At the maximum operating pressure of 1.0 MPa, theoretical push force reaches 804 N.
Yes, provided the mounting, port size (PT1/8), and magnet option match. The SCJ32 body is slightly longer to house the adjusting screw, so check the 182 mm + stroke base length against your available space. The adjustable stroke lets you fine-tune the end position, which a fixed-stroke SC32 cannot do.
