About the Airtac SCJ32 Standard Cylinder SCJ32X40-30TC
The SCJ32X40-30 is a 32 mm bore double-acting single-rod pneumatic cylinder with a rear adjusting screw that provides up to 30 mm of field-adjustable stroke-end control. This lets commissioning engineers fine-tune the piston stop position without changing the cylinder or adding external hard stops. With a 12 mm diameter piston rod and PT1/8 port, it delivers 402 N of push force at 0.5 MPa, making it a compact yet precise actuator for light automation tasks.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (order code F-SC32TC), which allows the cylinder body to pivot and absorb misalignment in swinging or articulating linkages. The standard TPU seal operates reliably from -20 to +70 °C with filtered air. The body length A is 182 mm, and the integral air cushion is 21 mm long, decelerating the piston smoothly at stroke end.
Airtac SCJ32 Standard Cylinder SCJ32X40-30TC Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X40-30TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 40 mm |
| Stroke adjustment | Up to 30 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 SCJ32X40-30TC Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position during machine commissioning without swapping cylinders. The 30 mm adjustment range allows for precise setup of gripper or pusher mechanisms in small assembly cells.
Format Changeover
Quickly adjust a stop gate or diverter stroke on a packaging line when changing product sizes. The rear screw allows operators to set a new stop position in seconds, reducing downtime between batches.
Wear Take-Up
Compensate for gradual wear on tooling or contact surfaces by slightly extending the effective stroke. This maintains consistent part contact pressure in clamping or pressing operations without reprogramming the machine.
Is the Airtac SCJ32 Standard Cylinder SCJ32X40-30TC the Right Cylinder?
Choose the SCJ32 when you need a compact adjustable-stroke cylinder for light-duty positioning. If 402 N push at 0.5 MPa is insufficient, step up to the 40 mm bore SCJ40, which provides 628 N of push force. For applications requiring a fixed, non-adjustable stroke, the standard SC32 fixed-stroke cylinder is a simpler and more cost-effective alternative. The SCJ32 is also not suitable for high side-loads; if the rod must support a transverse force, use an external linear guide or switch to a guided cylinder.
For direct replacement, match the 32 mm bore, 40 mm nominal stroke, 30 mm adjustable range, PT port thread, and TC trunnion mounting with the TCM1 bracket. This cylinder is a genuine AirTAC SCJ adjustable-stroke unit, not an ISO 15552 type.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ32X40-30TC 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 pressure is 1.0 MPa, producing up to 724 N of push force. The force is identical to the standard SC32 fixed-stroke cylinder.
Yes, if you need field-adjustable stroke control. The SCJ32X40-30 matches the mounting footprint of an SC32 with TC trunnion. Ensure your application can accommodate the slightly longer body length (A=182 mm) required for the rear adjusting screw mechanism.
