About the Airtac SCJ32 Standard Cylinder SCJ32X450-75S
The SCJ32X450-75S is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end adjustment at your fingertips. Its rear-cap screw provides a 75 mm adjustable range, letting you dial in the exact end position without swapping the cylinder. With a 12 mm rod and PT1/8 ports, this 32 mm bore unit delivers 402 N of push force at 0.5 MPa.
A built-in magnet (denoted by the -S suffix) allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke sensing. The body length A(SCJ) is 182 mm, and the adjustable air cushion decelerates the piston smoothly. This model is ideal for commissioning trials and format changeovers where the stroke must be field-tuned.
Airtac SCJ32 Standard Cylinder SCJ32X450-75S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X450-75S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 450 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 SCJ32X450-75S Is Used
Commissioning & Setup
The 75 mm adjustment range lets technicians quickly dial in the exact stroke end during machine commissioning, eliminating the need for hard stops or cylinder swaps.
Product Changeover
On packaging lines, the adjustable stroke allows operators to reposition the end stop for different box sizes without mechanical rework, reducing downtime.
Wear Compensation
In clamping fixtures, the screw can be advanced over time to take up mechanical wear in tooling, maintaining consistent clamping force without replacing the actuator.
Is the Airtac SCJ32 Standard Cylinder SCJ32X450-75S the Right Cylinder?
Choose the SCJ32X450-75S when you need to fine-tune the stroke end on a 32 mm bore platform. If your force requirement grows, stepping up to the 40 mm bore SCJ40 series provides 628 N of push at 0.5 MPa. For applications that do not require field adjustability, the fixed-stroke SC32 cylinder is a simpler alternative. A direct replacement must match the 32 mm bore, 450 mm nominal stroke, 75 mm adjust range, PT thread, and the -S magnet option.
At a 450 mm stroke, be mindful of side loading on the 12 mm rod. If the load is not guided externally, consider adding a linear guide or switching to a guided cylinder to prevent rod bending and premature seal wear.
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 SCJ32X450-75S FAQ
At 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. The maximum operating push force at 0.9 MPa is 724 N.
Only if your design can accommodate the longer body length A(SCJ) of 182 mm and you need the 75 mm stroke-end adjustment. Ensure the port thread (PT1/8), magnet option (-S), and mounting style match your existing setup.
