About the Airtac SCJ100 Standard Cylinder SCJ100X80-50SH
The SCJ100X80-50SH is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw, allowing the stroke end position to be fine-tuned within a 50 mm range. This model delivers a substantial push force of 3927 N at 0.5 MPa, making it suitable for heavy-duty applications requiring precise end-stop calibration.
Built with a 25 mm diameter piston rod and PT1/2 ports, it features a 29 mm air cushion for smooth deceleration. The -SH suffix specifies a built-in magnet for sensor mounting and Viton (FKM) seals, extending the operating temperature range to 0–150°C for demanding thermal environments.
Airtac SCJ100 Standard Cylinder SCJ100X80-50SH Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X80-50SH |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 80 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 SCJ100X80-50SH Is Used
Format Changeovers
Quickly adjust end-stops on packaging or filling machines when switching between product sizes, reducing downtime without replacing the cylinder.
Hot Environment Presses
The Viton seals withstand 0-150°C, making this cylinder ideal for clamping or ejecting parts in heated laminating or thermoforming presses.
Wear Compensation
Fine-tune the stroke end to compensate for tooling wear in automated grinding or cutting fixtures, maintaining process accuracy over time.
Is the Airtac SCJ100 Standard Cylinder SCJ100X80-50SH the Right Cylinder?
Choose the SCJ100 bore for its 3927 N push force at 0.5 MPa. If your application needs less force, the 80 mm bore provides 2513 N. For a fixed stroke without adjustability, the standard SC series is a direct alternative. This model is a direct replacement for another AirTAC SCJ100X80-50 with a magnet and Viton seals.
For strokes over 300 mm, consider external guides to manage side loads and prevent rod bending. The rear screw adjusts the stroke end only and does not alter the cylinder's force output or speed.
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 SCJ100X80-50SH FAQ
At 0.5 MPa, it generates 3927 N pushing and 3681 N pulling. The maximum push force at 0.9 MPa is 7068 N.
No, like all pneumatic cylinders, it will drift if air pressure is lost. The air cushion only decelerates the piston, and the adjusting screw sets the stroke end—neither locks the rod. Use an external mechanical brake or pilot-operated check valve for load holding.
