About the Airtac SCJ32 Standard Cylinder SCJ32X200-50SN
The SCJ32X200-50SN is a double-acting, single-rod pneumatic cylinder with a 50 mm rear adjusting screw, letting you fine-tune the stroke end position on the fly without replacing the unit. Its 32 mm bore delivers 402 N of push force at 0.5 MPa, making it a compact workhorse for light positioning and clamping tasks.
This model is configured with an NBR (nitrile) seal for general-purpose air service and a built-in magnet (S suffix) that allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke sensing. The rod is 12 mm in diameter with an M10x1.25 thread, and the body length A is 182 mm, providing a rigid yet space-efficient assembly.
Airtac SCJ32 Standard Cylinder SCJ32X200-50SN Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-50SN |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 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 SCJ32X200-50SN Is Used
Commissioning & Setup
Dial in the exact 200 mm stroke end-stop during machine commissioning with the 50 mm adjustment range, eliminating the need to swap cylinders or machine custom hard stops.
Light Assembly Stops
Fine-tune the push-to-stop position for small-part pressing or staking fixtures, where the 402 N force at 0.5 MPa provides controlled, repeatable contact without damaging components.
Sensor-Controlled Diverter
Combine the built-in magnet with CMSG sensors to create a compact diverter gate on a conveyor line, adjusting the stroke end to handle different package widths on the fly.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-50SN the Right Cylinder?
Step up to the 40 mm bore (628 N push at 0.5 MPa) if your application demands more force, or downsize to a fixed-stroke SC32 if you no longer need field adjustability. This SCJ is a direct dimensional replacement only for another AirTAC SCJ32 with a 200 mm nominal stroke and a 50 mm adjust range, matching PT ports and the same sensor-ready magnet configuration.
For this 200 mm stroke, ensure the load is guided to prevent side-loading and rod bending. If the cylinder must hold a position without air pressure, an external rod lock or pilot-operated check valve is required, as the air cushion and adjusting screw provide no mechanical locking function.
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 SCJ32X200-50SN FAQ
At the standard 0.5 MPa operating pressure, it generates 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.
Only if you need the 50 mm adjustable stroke feature. The SCJ body is slightly longer than a fixed SC of the same bore. It is a direct replacement for another SCJ32X200-50SN with the same NBR seals, PT ports, and built-in magnet. It is not dimensionally interchangeable with ISO 15552 cylinders.
