About the Airtac SCJ32 Standard Cylinder SCJ32X275-50S
The SCJ32X275-50S is a double-acting, single-rod pneumatic cylinder that puts a 50 mm field-adjustable stroke range at your fingertips. With a 32 mm bore and 12 mm rod, it delivers 402 N of push force at 0.5 MPa, scaling up to 724 N at 0.9 MPa. The rear-cap adjusting screw lets you fine-tune the stroke end position without removing the cylinder, making it ideal for commissioning trials or format changeovers on compact machinery. This model includes a built-in magnet for direct mounting of CMSG/DMSG sensors.
Built on the proven SC tie-rod platform, the SCJ32X275-50S uses PT1/8 ports and an M10x1.25 rod thread. Its 21 mm air cushion decelerates the piston quietly at the end of travel. The 275 mm nominal stroke is well within the 1000 mm maximum for the 32 bore, and the 50 mm adjustment range gives you the flexibility to dial in the exact stopping point for applications like precision dispensing or small-part clamping where overtravel must be eliminated.
Airtac SCJ32 Standard Cylinder SCJ32X275-50S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X275-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 275 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 SCJ32X275-50S Is Used
Commissioning & Setup
The 50 mm adjustment screw allows technicians to precisely set the end-of-stroke position during machine startup, eliminating the need for shims or external hard stops.
Small-Part Stop Gates
Adjust the stroke end to match different product widths on a conveyor line without swapping the cylinder, reducing changeover time in packaging systems.
Lab Dispensing Systems
Fine-tune the plunger travel on a precision dispenser to control the exact volume of fluid dispensed, with sensor confirmation of the end position via the built-in magnet.
Is the Airtac SCJ32 Standard Cylinder SCJ32X275-50S the Right Cylinder?
Choose the SCJ32X275-50S when you need a compact, adjustable-stroke actuator with sensor feedback. If your application demands more force, stepping up to the SCJ40 series provides 628 N of push force at 0.5 MPa. For fixed-stroke applications where adjustment is not required, the standard SC32X275 cylinder is a direct alternative. This SCJ model is a direct replacement for any AirTAC SCJ32X275-50S with a PT port, basic mount, and magnet. For strokes of 275 mm, ensure the rod is not subjected to high side loads; if lateral forces are present, consider adding an external guide rail to prevent rod bending and premature seal wear.
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 SCJ32X275-50S FAQ
At the standard operating pressure of 0.5 MPa, this 32 mm bore cylinder produces 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N. The pull force is lower because the 12 mm rod reduces the effective piston area on the return stroke.
Yes, this is a genuine AirTAC SCJ32X275-50S with a 50 mm adjustable stroke, PT1/8 ports, a basic mount, and a built-in magnet for sensors. It is a direct dimensional and performance match for any AirTAC cylinder with the same model code. Always verify that the port thread (PT) and mounting style match your current setup.
