About the Airtac SCJ32 Standard Cylinder SCJ32X100-50S
The AirTAC SCJ32X100-50S is a double-acting, single-rod tie-rod cylinder featuring a rear-cap adjusting screw that provides up to 50 mm of field-adjustable stroke reduction. This allows fine-tuning of the piston end position without removing the cylinder, making it ideal for commissioning and format changeovers on compact machinery. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
With a 12 mm diameter piston rod and a push force of 402 N at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure), this 32 mm bore cylinder is suited for light clamping, sorting, and ejecting tasks. Its PT1/8 ports and M10x1.25 rod thread ensure straightforward pneumatic integration, while the 21 mm air cushion provides smooth deceleration.
Airtac SCJ32 Standard Cylinder SCJ32X100-50S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 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 SCJ32X100-50S Is Used
Commissioning Fine-Tuning
The 50 mm adjustment screw allows engineers to precisely set the stroke end position during initial machine setup without needing to swap cylinders or fabricate custom hard stops.
Small-Part Sorting Gates
Ideal for actuating diverter gates on compact conveyors where the stroke length may need to be reduced to match different product widths, adjusted easily via the rear screw.
Wear Compensation in Clamps
In light-duty clamping fixtures, the adjustable stroke can be periodically shortened to compensate for jaw or pad wear, maintaining consistent clamping pressure without reprogramming.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-50S the Right Cylinder?
Choose the SCJ32 bore for applications requiring up to 402 N of push force at standard plant pressure. If your load demands more force, stepping up to the SCJ40 bore provides 628 N of push force at the same 0.5 MPa. This adjustable-stroke model is the right choice over a fixed-stroke SC cylinder when the exact end position must be dialed in on the machine, such as for wear compensation or multi-product setups. For direct replacement, match an SCJ32 cylinder with a 100 mm nominal stroke, a 50 mm adjustment range, PT ports, and a basic mount. If the application involves significant side loads, an external guide rail is recommended to prevent rod bending.
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 SCJ32X100-50S FAQ
At 0.5 MPa, the cylinder provides a push force of 402 N and a pull force of 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N.
Yes, it can replace an SC32X100 if you need the ability to fine-tune the stroke end. The SCJ body length is slightly longer than the fixed SC to accommodate the adjusting screw, so ensure you have clearance at the rear cap.
