About the Airtac SCJ32 Standard Cylinder SCJ32X45-10
The AirTAC SCJ32X45-10 is a double-acting, single-rod tie-rod cylinder with a field-adjustable stroke end. A rear-cap adjusting screw allows the effective stroke to be shortened by up to 10 mm from the nominal 45 mm maximum, making it ideal for fine-tuning end positions during commissioning or format changes without swapping the cylinder.
With a 12 mm diameter piston rod and PT1/8 ports, this 32 mm bore unit delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The body length A(SCJ) is 182 mm, and it features an adjustable air cushion of 21 mm for smooth deceleration. It operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C.
Airtac SCJ32 Standard Cylinder SCJ32X45-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X45-10 |
|---|---|
| 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 SCJ32X45-10 Is Used
Commissioning & Setup
The 10 mm adjustability allows technicians to dial in the exact stroke end position on a new machine without needing to fabricate custom stops or swap out fixed-stroke cylinders during initial trials.
Wear Compensation
In clamping or pressing fixtures, the adjustable screw can be used to take up mechanical wear on tooling or contact surfaces over time, maintaining consistent clamping force without replacing the actuator.
Small Part Stops & Gates
Ideal for creating adjustable end-stops on small conveyor lines. The stroke can be fine-tuned to handle different product sizes, providing a quick mechanical changeover for short-run packaging tasks.
Is the Airtac SCJ32 Standard Cylinder SCJ32X45-10 the Right Cylinder?
Select the SCJ32 when you need a compact, adjustable stroke in light automation tasks. If the 402 N push force at 0.5 MPa is insufficient, stepping up to a 40 mm bore provides 628 N of push force. For applications requiring a fixed, non-adjustable stroke, the standard SC32 cylinder is a simpler alternative. This model is a direct replacement for an AirTAC SCJ32X45-10 with basic mounting, TPU seals, and PT threads. For strokes over 300 mm in any bore, evaluate side-loading on the rod and consider an external guide or a guided cylinder to prevent bending.
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 SCJ32X45-10 FAQ
At the standard operating pressure of 0.5 MPa, 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 lower due to the area of the 12 mm rod.
You can, provided the 45 mm nominal stroke and 10 mm adjustment range meet your needs. The SCJ body is slightly longer to house the adjusting screw. Ensure the mounting style, port thread (PT), and magnet option match your existing setup for a direct dimensional fit.
