About the Airtac SCJ32 Standard Cylinder SCJ32X160-100
The SCJ32X160-100 is a 32 mm bore, double-acting single-rod air cylinder that provides a generous 100 mm of field-adjustable stroke-end reduction via a rear-cap screw. This lets you fine-tune the piston stop position anywhere from 60 mm up to the full 160 mm nominal stroke without swapping the cylinder or adding external hard stops, which is ideal for commissioning trials and format changeovers on compact machinery.
With a 12 mm diameter piston rod and PT1/8 pneumatic ports, this model delivers 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). The body length A(SCJ) is 182 mm plus stroke, and it includes a 21 mm air cushion for smooth end-of-travel deceleration. The standard TPU seal suits ambient temperatures from -20 to +70 °C.
Airtac SCJ32 Standard Cylinder SCJ32X160-100 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X160-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 160 mm |
| Stroke adjustment | Up to 100 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 SCJ32X160-100 Is Used
Commissioning & Setup
The 100 mm rear adjustment screw lets technicians quickly fine-tune the actuator end-stop on a new assembly line without fabricating custom mechanical stops, cutting commissioning time.
Wear Compensation
In clamping or pressing fixtures, the adjustable stroke can be periodically reduced to take up mechanical wear on tooling or workpieces, maintaining consistent clamp force over time.
Product Format Changeover
On a packaging line handling multiple box sizes, operators can adjust the cylinder stroke to match different product widths, enabling rapid changeover without replacing the actuator.
Is the Airtac SCJ32 Standard Cylinder SCJ32X160-100 the Right Cylinder?
Choose the SCJ32 when your application needs roughly 400 N of push force at standard plant air pressure and the ability to dial in the exact stroke end on the machine. If you require more force, stepping up to the 40 mm bore SCJ40 series provides 628 N of push at 0.5 MPa. For applications where the stroke length is fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a more economical alternative. This model is a direct replacement for another AirTAC SCJ32 adjustable cylinder with a 160 mm nominal stroke, a -100 adjust range, PT ports, and basic mounting.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ32X160-100 FAQ
The push force is 402 N at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa. The pull force on the return stroke is 345 N at 0.5 MPa because the 12 mm rod reduces the effective piston area.
A screw in the rear cap acts as an internal, adjustable end-stop for the piston. Turning the screw changes the retracted stroke end position by up to 100 mm, giving you an effective stroke range from 60 mm to the full 160 mm. It does not adjust the cylinder's force or speed.
