About the Airtac SCJ32 Standard Cylinder SCJ32X275-100
The SCJ32X275-100 is a double-acting, single-rod pneumatic cylinder with a 100 mm field-adjustable stroke range, allowing you to dial in the exact stroke end position from 175 mm up to the nominal 275 mm. This 32 mm bore unit delivers 402 N of push force at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa, making it a compact yet capable actuator for light automation tasks.
Its tie-rod construction houses a 12 mm diameter piston rod with an M10x1.25 male thread, and the PT1/8 ports supply air filtered to 40 µm. The cylinder includes an adjustable air cushion (21 mm long) to decelerate the piston quietly, and the rear adjusting screw lets commissioning engineers fine-tune the end stop without adding external hard stops or changing the cylinder body, which has a base length of 182 mm.
Airtac SCJ32 Standard Cylinder SCJ32X275-100 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X275-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 275 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 SCJ32X275-100 Is Used
End-Stop Commissioning
During machine bring-up, technicians can back the rear screw out to gradually increase stroke until the tooling aligns perfectly, eliminating the need to swap multiple fixed-stroke cylinders.
Wear Take-Up on Stops
In repetitive pushing or clamping tasks, the adjustable screw compensates for mechanical wear on the workpiece or stop surface, maintaining consistent engagement without reprogramming.
Small-Part Ejector Adjustment
Fine-tune the ejector stroke on a pick-and-place nest to handle slightly different component heights, using the 100 mm range to dial in the exact push distance required.
Is the Airtac SCJ32 Standard Cylinder SCJ32X275-100 the Right Cylinder?
Choose the SCJ32X275-100 when your application requires a stroke near 275 mm but you need to trim the retracted or extended end position by up to 100 mm during setup or format changes. If you need more push force, step up to the SCJ40 series, which provides 628 N at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC32X275 is a simpler alternative. This model is a direct replacement for another AirTAC SCJ32 cylinder of the same bore, nominal stroke, 100 mm adjust range, and PT port thread. For strokes over 300 mm, consider adding an external guide rail to prevent side-loading and rod bending.
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 SCJ32X275-100 FAQ
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. At the maximum 0.9 MPa, push force reaches 724 N. Because it is a single-rod cylinder, the push force is always greater than the pull force due to the rod area.
Yes, the SCJ32X275-100 can replace an SC32 of similar stroke if you need the 100 mm stroke-end adjustment. The body length is slightly longer (A=182 mm) to accommodate the rear adjusting screw. Ensure the port size (PT1/8), rod thread (M10x1.25), and mounting style match your existing setup.
