About the Airtac SCJ32 Standard Cylinder SCJ32X210-50
The SCJ32X210-50 is a double-acting, single-rod pneumatic cylinder with a 32 mm bore and a 210 mm nominal stroke, featuring a rear adjusting screw that provides up to 50 mm of stroke-end adjustment. This allows you to dial in the exact piston stop position during commissioning or changeovers without replacing the cylinder or adding external hard stops. The 12 mm diameter piston rod and PT1/8 ports are standard for this bore size.
At 0.5 MPa air pressure, the cylinder delivers 402 N of push force and 345 N on the pull stroke, making it suitable for light clamping, sorting, and diverting tasks. The body length A is 182 mm, and the unit includes an adjustable air cushion for smooth deceleration. This model is a basic configuration with TPU seals and PT threads, ideal for general industrial environments operating between -20 and +70 °C.
Airtac SCJ32 Standard Cylinder SCJ32X210-50 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X210-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 210 mm |
| Stroke adjustment | Up to 50 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 SCJ32X210-50 Is Used
Commissioning & Setup
Fine-tune the end stop of a material stop gate during machine setup. The 50 mm adjustment range lets technicians quickly dial in the correct position for different product sizes without fabricating new brackets.
Small Part Diverting
Adjust the stroke end of a diverter arm on a conveyor line. When switching between product batches, the screw adjustment compensates for different package widths, ensuring reliable sorting with 402 N of push force.
Wear Compensation
In a repetitive pressing or clamping fixture, the adjustable stroke can be extended slightly over time to compensate for pad wear or material compression, maintaining consistent clamping pressure without reprogramming the machine.
Is the Airtac SCJ32 Standard Cylinder SCJ32X210-50 the Right Cylinder?
Choose this SCJ32 model when your application requires a stroke near 210 mm but you need the flexibility to shorten the end position by up to 50 mm on the machine. If you need more force, stepping up to the 40 mm bore SCJ40 series provides 628 N of push force at the same 0.5 MPa pressure. For applications where the stroke length is fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a more economical choice. For direct replacement, match the 32 mm bore, 210 mm nominal stroke, 50 mm adjust range, and PT port thread.
For this 210 mm stroke length, be mindful of side loads on the 12 mm rod. If the load is not guided externally, consider adding a guide rail 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 (-50)
- ✓ 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 SCJ32X210-50 FAQ
At the standard operating pressure of 0.5 MPa, it generates 402 N of push force and 345 N of pull force. The maximum push force at the 0.9 MPa upper limit is 724 N. The pull force is lower due to the area of the 12 mm piston rod.
Yes, if you need the ability to adjust the stroke end. The SCJ32X210-50 has the same mounting footprint and port size (PT1/8) as an SC32, but the body is slightly longer to house the adjusting screw. Ensure your 210 mm nominal stroke and the 50 mm adjustment range match your mechanical requirements.
