About the Airtac SCJ100 Standard Cylinder SCJ100X50-50
The SCJ100X50-50 delivers a substantial 3927 N of push force at 0.5 MPa, making it a powerful solution for heavy-duty applications requiring a fine-tunable stroke. Its rear-mounted adjusting screw provides a 50 mm range to precisely set the stroke end position, which is invaluable during commissioning or for accommodating part tolerances without replacing the cylinder.
This single-rod, tie-rod cylinder features a 25 mm diameter piston rod and PT1/2 ports. With a body length of 245 mm and a 29 mm air cushion, it smoothly decelerates high-inertia loads at the end of its travel. The maximum operating pressure is 1.0 MPa, where it can theoretically output over 7000 N of force.
Airtac SCJ100 Standard Cylinder SCJ100X50-50 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X50-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 50 mm |
| Stroke adjustment | Up to 50 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 29 mm |
| Max stroke | Up to 1500 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCJ100 Standard Cylinder SCJ100X50-50 Is Used
Press-Fit Depth Adjustment
Fine-tunes the insertion depth of a pressing tool to accommodate varying component heights or to compensate for tooling wear over time.
Product Gate Actuation
Operates a diverter gate on a heavy-duty conveyor line, where the 50 mm adjustment allows the gate opening to be optimized for different package sizes.
Clamp Stroke Setting
Sets the final clamping position on a large welding fixture, ensuring consistent pressure is applied to workpieces with slight dimensional variations.
Is the Airtac SCJ100 Standard Cylinder SCJ100X50-50 the Right Cylinder?
Select the SCJ100X50-50 when you need the force of a 100 mm bore with the ability to dial in the stroke end by up to 50 mm. If your application requires a fixed, non-adjustable stroke, the standard SC100X50 is a more economical alternative. For higher force, stepping up to the SCJ125 bore provides 6136 N of push force at 0.5 MPa. A direct replacement must match the 100 mm bore, 50 mm nominal stroke, 50 mm adjust range, PT ports, and basic mounting style.
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 SCJ100 Standard Cylinder SCJ100X50-50 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical force at 1.0 MPa is 801 kgf.
Yes, the SCJ100X50-50 shares the same mounting footprint and port size as the SC100X50. The adjustable screw adds length to the rear cap, so ensure you have clearance behind the cylinder. It allows you to shorten the stroke end by up to 50 mm.
