About the Airtac SCJ32 Standard Cylinder SCJ32X95-50
The SCJ32X95-50 is a 32mm bore, double-acting single-rod pneumatic cylinder with a field-adjustable stroke end. Its rear-cap adjusting screw provides a 50mm adjustment range, letting you fine-tune the effective stroke from 95mm down to 45mm without replacing the cylinder. This model delivers 402N of push force at 0.5MPa and uses a 12mm diameter piston rod with an M10x1.25 rod thread for end tooling.
Built as a durable tie-rod cylinder, the SCJ32X95-50 features a 21mm air cushion for smooth deceleration and a body length of 182mm. It operates on filtered air from 0.15 to 1.0MPa and handles speeds from 30 to 800mm/s. The standard PT1/8 port and TPU seals suit general industrial environments from -20 to +70°C. This model is ideal for applications where stroke length needs on-machine tweaking during commissioning or format changes.
Airtac SCJ32 Standard Cylinder SCJ32X95-50 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X95-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 95 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 SCJ32X95-50 Is Used
Commissioning & Setup
Fine-tune the end position of a pusher or stop during machine commissioning. The 50mm screw adjustment allows rapid, tool-free changes to dial in the exact stroke needed without swapping cylinders.
Small-Part Diverter Gates
Adjust the gate opening on a conveyor diverter for different product sizes. The adjustable stroke lets operators quickly change the throw distance to handle varying box or package widths on a packaging line.
Wear Compensation in Clamps
Use the stroke-end screw to take up mechanical wear in a clamping fixture. Over time, as gripper pads wear down, the stroke can be extended slightly to maintain consistent clamping pressure and part registration.
Is the Airtac SCJ32 Standard Cylinder SCJ32X95-50 the Right Cylinder?
Choose the SCJ32X95-50 when you need a compact, adjustable stroke in the 32mm bore class. If your force requirement is higher, stepping up to the SCJ40 series provides 628N of push force at 0.5MPa. For applications needing a fixed, non-adjustable stroke, the standard SC32 series is a simpler alternative. This SCJ cylinder is a direct replacement for another AirTAC SCJ32 with a 95mm nominal stroke and 50mm adjustment range, matching PT ports and basic mounting.
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 SCJ32X95-50 FAQ
At 0.5MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The push force is higher because the single piston rod reduces the effective area on the return stroke. Maximum push force at 0.9MPa is 724N.
Yes, if you need the 50mm stroke adjustability. The SCJ32X95-50 has the same 32mm bore, port size, and mounting footprint as an SC32, but the rear adjusting screw adds length. Ensure your machine has clearance for the slightly longer SCJ body and that the adjustable stroke range covers your required motion.
