About the Airtac SCJ100 Standard Cylinder SCJ100X30-30
The SCJ100X30-30 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the 30 mm nominal stroke by up to 30 mm using the rear-cap screw. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa, making it a compact powerhouse for heavy clamping and pressing tasks.
This model uses a 25 mm diameter piston rod, PT1/2 ports, and a 29 mm air cushion for smooth deceleration. The tie-rod body measures 245 mm (A dimension), providing a rigid, serviceable structure. As a genuine AirTAC SCJ unit, it offers dependable, repeatable performance for applications where the stroke must be dialed in precisely on the machine.
Airtac SCJ100 Standard Cylinder SCJ100X30-30 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X30-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 30 mm |
| Stroke adjustment | Up to 30 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 SCJ100X30-30 Is Used
Precision End-Stop Adjustment
Ideal for commissioning and fine-tuning automated assembly fixtures where the final actuator position must be dialed in to within a fraction of a millimeter after installation, without swapping the cylinder.
Wear Compensation in Material Handling
Used on heavy-duty pushers and reject stations on conveyors. The 30 mm adjustment range allows operators to compensate for wear on contact pads or guide rails, maintaining consistent product positioning over time.
Heavy Clamping with Variable Thickness
Suited for clamping workpieces of varying thicknesses in welding or machining fixtures. The 3927 N push force at 0.5 MPa provides a secure hold, while the adjustable stroke prevents over-travel on thinner parts.
Is the Airtac SCJ100 Standard Cylinder SCJ100X30-30 the Right Cylinder?
Choose the SCJ100X30-30 when you need high force in a short, tunable stroke. If 3927 N of push force at 0.5 MPa is more than required, stepping down to an 80 mm bore (2513 N push) can reduce air consumption and physical size. For applications requiring a fixed, non-adjustable stroke, the standard SC100 series is a simpler, cost-effective alternative. This is a direct replacement for any AirTAC SCJ100X30-30 cylinder with PT ports and basic mounting. For strokes of 300 mm or more, evaluate side-loading on the 25 mm rod and consider an external guide or a guided cylinder to prevent rod bending.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ100X30-30 FAQ
A rear-cap adjusting screw limits the piston's retraction, effectively shortening the stroke end position by up to 30 mm. The 30 mm nominal stroke is the maximum; you can reduce it anywhere within the 30 mm adjustment range to fine-tune the cylinder's stopping point for your specific application.
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. Because it is a single-rod cylinder, the push force is higher than the pull force due to the area of the 25 mm rod. The maximum push force at the 0.9 MPa operating limit is 7068 N.
