About the Airtac SCJ32 Standard Cylinder SCJ32X160-40
The SCJ32X160-40 is a double-acting, single-rod pneumatic cylinder built for applications where the stroke end must be dialled in precisely on the machine. Its rear-cap adjusting screw provides a 40 mm fine-tuning range, letting you shorten the 160 mm nominal stroke to suit commissioning trials or format changes without swapping the cylinder. The 12 mm diameter piston rod and 21 mm air cushion deliver reliable deceleration.
At 0.5 MPa supply pressure, this 32 mm bore unit generates 402 N of push force and 345 N on the pull stroke. The body length A is 182 mm, and it uses a PT1/8 port. This basic-configuration model ships with a TPU seal, suiting standard -20 to +70 °C environments, and is a direct replacement for any AirTAC SCJ32X160-40 with matching port and mounting.
Airtac SCJ32 Standard Cylinder SCJ32X160-40 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X160-40 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 160 mm |
| Stroke adjustment | Up to 40 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 SCJ32X160-40 Is Used
Commissioning & Setup
Field technicians use the 40 mm adjustment screw to fine-tune the end-stop position during initial machine setup, eliminating the need to shim or reposition the cylinder body.
Small-Part Diverting
On packaging lines, the adjustable stroke lets operators quickly change the diverting gate throw to handle different box sizes without mechanical rework.
Wear Take-Up
In cyclic pressing or clamping fixtures, the screw compensates for pad wear over time, maintaining consistent contact force without replacing the actuator.
Is the Airtac SCJ32 Standard Cylinder SCJ32X160-40 the Right Cylinder?
Choose the SCJ32X160-40 when you need field-adjustable stroke control in a compact 32 mm bore package. If your force requirement grows, stepping up to the 40 mm bore (SCJ40) raises push force to 628 N at 0.5 MPa. For fixed-stroke applications where no adjustment is needed, the standard SC32 series offers a simpler, lighter alternative. This model replaces any AirTAC SCJ32 cylinder with a 160 mm nominal stroke and a 40 mm adjustment range, provided the port thread (PT) and basic mounting match. For strokes of 300 mm or more, evaluate side-load conditions and consider an external guide rail to protect the rod bearing from bending moments.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-40)
- ✓ 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 SCJ32X160-40 FAQ
At 0.5 MPa air pressure, it delivers 402 N pushing force and 345 N pulling force. The maximum push force at the 1.0 MPa operating limit is 724 N, which equates to approximately 82 kgf.
Yes, if you need adjustable stroke. The SCJ32X160-40 shares the same bore, port size (PT1/8), and tie-rod mounting footprint as the SC32 series. Ensure your mounting and magnet options match, and confirm the 40 mm adjustment range suits your process.
