About the Airtac SCJ32 Standard Cylinder SCJ32X160-50S
The SCJ32X160-50S is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning directly on the machine. Its rear-cap adjusting screw provides a 50 mm adjustable range, letting you dial in the exact 160 mm nominal stroke without swapping the cylinder or adding external hard stops. The built-in magnet allows CMSG/DMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection.
At 0.5 MPa, this 32 mm bore unit delivers 402 N of push force and 345 N on the pull stroke, making it a capable actuator for light pressing, sorting, and diverting tasks. The 12 mm diameter piston rod and M10x1.25 rod thread are standard for the bore, while the 21 mm air cushion at each end decelerates the piston smoothly. The body length A(SCJ) is 182 mm, providing a compact envelope for integration into tight machine spaces.
Airtac SCJ32 Standard Cylinder SCJ32X160-50S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X160-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 160 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 SCJ32X160-50S Is Used
Commissioning & Setup
The 50 mm adjustment range allows technicians to fine-tune the end position during machine commissioning without cutting brackets or re-drilling mounting holes, dramatically speeding up the setup of new packaging or assembly lines.
Wear Compensation
In high-cycle diverters and sorters, mechanical stops can wear. The SCJ's rear screw lets operators quickly take up the slack, restoring precise positioning without shutting down the line for a cylinder change.
Format Changeovers
When a machine processes different product sizes, the adjustable stroke enables a single cylinder to handle multiple formats. A quick turn of the screw adapts the stop position for a new box height or pallet width.
Is the Airtac SCJ32 Standard Cylinder SCJ32X160-50S the Right Cylinder?
Choose the SCJ32X160-50S when you need to commission a stroke length precisely on the machine or accommodate minor process variations over time. If your force requirement grows, stepping up to the 40 mm bore SCJ40 series provides a significant jump to 628 N of push force at the same 0.5 MPa pressure. For applications where the stroke is permanently fixed and never needs adjustment, the standard SC32 fixed-stroke cylinder is a simpler, cost-effective alternative.
This model is a direct replacement for another AirTAC SCJ32 adjustable-stroke cylinder with a 160 mm nominal stroke, a 50 mm adjust range, PT ports, a basic mount, and a magnet. For strokes of 300 mm or more, consider an external guide rail or a guided cylinder to protect the 12 mm rod from side-loading and bending moments.
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 SCJ32X160-50S FAQ
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. The theoretical force at 1.0 MPa is 82 kgf. The adjustable stroke screw does not change the cylinder's force output.
Yes, you can replace an SC32 with an SCJ32 if you need the field-adjustable stroke feature. Ensure the nominal stroke, port thread (PT), and magnet option (S) match. The SCJ body is slightly longer to house the adjusting screw, so verify your machine has the clearance for the 182 mm body length.
