About the Airtac SCJ32 Standard Cylinder SCJ32X50-50S
The SCJ32X50-50S is a compact double-acting, single-rod cylinder that puts precise stroke-end tuning directly on the machine. Its rear adjusting screw provides a full 50 mm of adjustment range, letting technicians dial in the exact stop position during commissioning or changeovers without swapping the cylinder. With a 12 mm rod and 402 N of push force at 0.5 MPa, it handles light positioning and clamping tasks efficiently.
This model includes a built-in magnet (-S), allowing standard CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable, non-contact end-of-stroke sensing. The body length A(SCJ) is 182 mm, and the adjustable air cushion decelerates the piston smoothly at both ends. It uses PT1/8 ports and an M10x1.25 rod thread, making it a direct fit for existing AirTAC SCJ32 setups.
Airtac SCJ32 Standard Cylinder SCJ32X50-50S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X50-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 50 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 SCJ32X50-50S Is Used
Commissioning & Setup
Fine-tune the retract stroke end-stop on the fly during initial machine setup, eliminating the need to shim or reposition the entire cylinder for a perfect fit.
Sensing & Positioning
The built-in magnet enables direct mounting of CMSG/DMSG sensors, providing precise piston position feedback for automated assembly fixtures and pick-and-place units.
Light Part Stops
Use the 50 mm adjustment range to create a variable end-stop for small products on a conveyor, allowing a single cylinder to handle multiple product sizes with a quick screw adjustment.
Is the Airtac SCJ32 Standard Cylinder SCJ32X50-50S the Right Cylinder?
Choose the SCJ32 when you need a light-duty, field-adjustable stroke in a compact footprint. If your application demands more push force, stepping up to the SCJ40 delivers 628 N at 0.5 MPa. For applications where the stroke never needs field adjustment, the fixed-stroke SC32 series offers a simpler, more cost-effective alternative. This unit is a direct replacement for any AirTAC SCJ32X50-50S cylinder with PT ports and a basic mount.
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 SCJ32X50-50S FAQ
At 0.5 MPa, it generates 402 N of push force and 345 N of pull force. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower because the 12 mm piston rod reduces the effective piston area on the return stroke.
Yes, if you need the 50 mm adjustable stroke feature. The SCJ32X50-50S has the same bore, port size (PT1/8), and rod thread (M10x1.25) as an SC32, but the body is slightly longer to house the adjusting screw. It is a direct mechanical upgrade when field adjustability is required.
