About the Airtac SCJ32 Standard Cylinder SCJ32X150-50S
The SCJ32X150-50S is a double-acting, single-rod pneumatic cylinder that puts precise stroke-end tuning directly in the hands of the machine builder. With a 50 mm rear adjusting screw, you can fine-tune the end position on the fly during commissioning or changeovers without swapping the cylinder or adding external hard stops. The 32 mm bore delivers 402 N of push force at 0.5 MPa, making it a capable actuator for light clamping, sorting, and diverting tasks.
This model includes a built-in magnet (-S), allowing CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable, non-contact position sensing. The 12 mm piston rod and PT1/8 ports keep the package compact, while the 21 mm air cushion at each end decelerates the piston quietly. The body length (A dimension) is 182 mm, and the standard TPU seals offer a working temperature range of -20 to +70 °C.
Airtac SCJ32 Standard Cylinder SCJ32X150-50S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X150-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 150 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 SCJ32X150-50S Is Used
Commissioning & Setup
The 50 mm adjustment range lets technicians dial in the exact stroke end position during initial machine setup, eliminating the need to machine custom stops or swap cylinders to get the motion profile just right.
Product Diverting
In packaging lines handling different box sizes, the adjustable stroke allows operators to quickly retune the pusher's end point for a new format, minimizing changeover downtime without any disassembly.
Wear Compensation
On clamping fixtures, the stroke can be incrementally extended over time to compensate for pad wear, maintaining consistent clamping force and part quality without replacing the cylinder or tooling.
Is the Airtac SCJ32 Standard Cylinder SCJ32X150-50S the Right Cylinder?
Step up to the SCJ40 bore if your application demands more than the 724 N of push force this 32 mm bore provides at the maximum 0.9 MPa operating pressure; the 40 mm bore delivers 1130 N at the same pressure. For applications that never require stroke adjustment, the fixed-stroke SC series is a simpler, more cost-effective alternative. If you need a direct replacement, match an AirTAC SCJ cylinder with a 32 mm bore, a 150 mm nominal stroke, a 50 mm adjustment range, PT ports, and a built-in magnet. This cylinder has a 150 mm stroke, which is well within the 1000 mm maximum standard stroke for the 32 mm bore, ensuring it is a standard catalog item.
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 SCJ32X150-50S FAQ
At the standard 0.5 MPa operating pressure, this single-rod cylinder provides 402 N of push force and 345 N of pull force. The push force is greater because the rod reduces the effective piston area on the return side. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N.
Yes, but only if you need the stroke adjustment feature. The SCJ32X150-50S shares the same bore, port size (PT1/8), and mounting accessories as a fixed-stroke SC32 cylinder. Ensure the 50 mm adjustment screw on the rear cap does not interfere with your machine's envelope, as the SCJ body is slightly longer than the equivalent SC.
