About the Airtac SCJ32 Standard Cylinder SCJ32X260-50
The SCJ32X260-50 is a 32 mm bore double-acting single-rod cylinder with a field-adjustable stroke, letting you fine-tune the end position by up to 50 mm via the rear-cap screw. At 0.5 MPa it delivers 402 N push and 345 N pull, with a 12 mm rod and PT1/8 ports, making it a compact solution for light automation tasks where commissioning or format changes demand on-machine stroke tweaking.
The tie-rod body (A length 182 mm) includes an adjustable air cushion (21 mm) for smooth deceleration. This model's 260 mm nominal stroke is well within the 1000 mm maximum for bore 32, and the 50 mm adjustment range provides generous end-stop flexibility without swapping the cylinder or adding external hard stops.
Airtac SCJ32 Standard Cylinder SCJ32X260-50 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X260-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 260 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 SCJ32X260-50 Is Used
Commissioning & Setup
Dial in the exact stroke end during machine commissioning without cutting rods or repositioning hard stops. The 50 mm screw adjustment lets technicians fine-tune the actuator throw quickly.
Small Part Stops & Gates
Use as an adjustable end-stop or diverter gate on light-duty conveyors. The 402 N push force handles small packages, and the stroke can be re-trimmed when product sizes change.
Wear Take-Up in Clamping
In clamping or pressing fixtures where tooling wears over time, the adjustable stroke compensates for material loss, maintaining consistent clamp pressure without mechanical shimming.
Is the Airtac SCJ32 Standard Cylinder SCJ32X260-50 the Right Cylinder?
Choose the SCJ32 when you need up to 402 N push at 0.5 MPa and the ability to trim the stroke end on the machine. If you need more force, the SCJ40 offers 628 N push at the same pressure. For applications where the stroke is fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a simpler, cost-effective alternative. A direct replacement must match the 32 mm bore, 260 mm nominal stroke, 50 mm adjust range, PT ports, and basic mounting. This model has no magnet; if sensor feedback is required, order the -S variant.
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 SCJ32X260-50 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N (due to the 12 mm rod area). At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. Always use the pull force for retraction calculations.
Yes, if you need the 50 mm adjustable stroke feature. The SCJ32 shares the same bore, rod, port, and mounting accessories as the SC32. Ensure the nominal stroke and adjust range match your machine's requirements, and confirm the slightly longer body length (182 mm) fits your space.
