About the Airtac SCJ32 Standard Cylinder SCJ32X45-10S
The SCJ32X45-10S is a 32 mm bore, single-rod double-acting cylinder with a rear-cap adjusting screw that provides up to 10 mm of field-adjustable stroke-end control. With a 12 mm diameter rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, making it a precise actuator for light positioning tasks. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model has a nominal stroke of 45 mm, well within the 1000 mm maximum standard stroke for the 32 mm bore. The tie-rod construction and 21 mm air cushion at each end ensure smooth, controlled deceleration. Its compact body length A(SCJ) of 182 mm plus stroke fits neatly into fixtures where fine-tuning the stop position without replacing the cylinder is a genuine time-saver during commissioning.
Airtac SCJ32 Standard Cylinder SCJ32X45-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X45-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 45 mm |
| Stroke adjustment | Up to 10 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 SCJ32X45-10S Is Used
Commissioning & Setup
Fine-tune the cylinder's end position by up to 10 mm during machine commissioning without swapping spacers or re-machining mounts, dramatically reducing setup time.
Wear Take-Up in Clamping
In light-duty clamping fixtures, the adjusting screw compensates for pad wear over time, maintaining consistent clamping force without reprogramming.
Small Part Stops
Adjust the physical stop point for different product sizes on a conveyor line. The 32 mm bore provides ample force for stopping small packages or components.
Is the Airtac SCJ32 Standard Cylinder SCJ32X45-10S the Right Cylinder?
Choose this 32 mm bore when your application needs a compact actuator with up to 402 N of push force. If you require more power, stepping up to the 40 mm bore provides 628 N of push at the same pressure. The built-in magnet (S suffix) is essential if you plan to use reed or solid-state sensors for position feedback; without it, external switch mounting becomes more complex. For applications requiring a fixed, non-adjustable stroke, the standard SC series is a simpler alternative.
This SCJ32X45-10S is a direct replacement for any AirTAC SCJ adjustable-stroke cylinder of the same 32 mm bore, 45 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting. If you are using a guided cylinder, the adjustable stroke can still be useful, but ensure side loads are managed by the external guide, not the cylinder rod bearing.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ32X45-10S FAQ
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. The maximum push force at 0.9 MPa is 724 N. Because it is a single-rod cylinder, the pull force is always lower due to the rod area.
A rear-cap screw sets the stroke end position within a 10 mm range, shortening the nominal 45 mm stroke. It is a physical stop, not a force or speed control. It can replace an SC of the same bore and stroke if you need field adjustability, but ensure the extra body length A(SCJ) of 182 mm plus stroke fits your space.
