About the Airtac SCJ32 Standard Cylinder SCJ32X80-10
The SCJ32X80-10 is a double-acting, single-rod pneumatic cylinder that puts stroke-end adjustment directly into the rear cap. With a 10 mm adjusting screw, you can dial the retract end position back from the nominal 80 mm stroke in seconds—ideal for commissioning trials, sensor alignment, or taking up mechanical wear without re-plumbing. Its 12 mm rod and M10x1.25 rod thread handle push forces of 402 N at 0.5 MPa and up to 724 N at 0.9 MPa.
This 32 mm bore tie-rod cylinder uses a PT1/8 port and includes an adjustable air cushion (21 mm long) for smooth deceleration. The body length A(SCJ) is 182 mm, keeping the envelope compact. Standard strokes for this bore go up to 1000 mm, so the 80 mm nominal stroke is well within standard range. The default seal is TPU, rated for -20 to +70 °C, and ports are PT thread.
Airtac SCJ32 Standard Cylinder SCJ32X80-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X80-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 80 mm |
| Stroke adjustment | Up to 10 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 SCJ32X80-10 Is Used
Commissioning & Setup
Dial in the exact retract stop during machine build and debug. The 10 mm screw lets technicians fine-tune the end position without cutting brackets or adding shims.
Small Part Ejectors
Adjust the eject stroke end to match different bin heights or conveyor positions on a packaging line. The 32 mm bore provides enough force for lightweight plastic or cardboard parts.
Wear Take-Up
Compensate for pad or gripper wear over time. A quick turn of the rear screw restores the precise end position without replacing the cylinder or reprogramming the PLC.
Is the Airtac SCJ32 Standard Cylinder SCJ32X80-10 the Right Cylinder?
Choose the SCJ32 when you need to fine-tune the stroke end on a compact machine. If the 402 N push force at 0.5 MPa is marginal, stepping up to the SCJ40 delivers 628 N push at the same pressure. For applications where the stroke never needs field adjustment, the fixed-stroke SC32 is a simpler, lower-cost alternative. This model is a direct replacement for any AirTAC SCJ32X80-10 with PT ports and basic mounting—match bore, nominal stroke, and the 10 mm adjust range. At 80 mm stroke, rod bending is not a concern under normal axial loads; if side loads are present, add an external guide rail.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ32X80-10 FAQ
At 0.5 MPa, it delivers 402 N pushing and 345 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The pull force is lower because the 12 mm rod reduces the effective piston area on the return stroke.
Yes, provided the mounting and port threads match. The SCJ32X80-10 has the same bore, rod, and port size as an SC32, but the body is slightly longer to house the adjusting screw. Ensure you have clearance at the rear cap for the screw and lock nut.
