About the Airtac SCJ100 Standard Cylinder SCJ100X400-100TC
The SCJ100X400-100TC is a double-acting, single-rod pneumatic cylinder with a 100 mm bore and a nominal 400 mm stroke, featuring a rear-cap adjusting screw that provides up to 100 mm of field-adjustable stroke-end reduction. This allows fine-tuning of the piston stop position without removing the cylinder, ideal for commissioning and format changeovers. It delivers 3927 N of push force at 0.5 MPa and 7068 N at the maximum operating pressure of 0.9 MPa, using a 25 mm diameter piston rod.
This model is configured with a centre trunnion (TC) mount, allowing the cylinder to pivot as it actuates, which is essential for swinging or arcing loads. The trunnion is supplied with the TCM1 bracket and uses the F-SC100TC mounting kit. Ports are PT1/2, and the cylinder body length A is 245 mm. It is a genuine AirTAC tie-rod cylinder, built for reliable, repeatable performance in demanding industrial sequences.
Airtac SCJ100 Standard Cylinder SCJ100X400-100TC Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X400-100TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 400 mm |
| Stroke adjustment | Up to 100 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 SCJ100X400-100TC Is Used
End-Stop Calibration
Use the 100 mm adjusting screw to precisely dial in the retract or extend stop position during machine commissioning, eliminating the need for shims or external hard stops on high-force pressing or clamping stations.
Part Transfer with Varied Stops
In a multi-product conveyor system, the adjustable stroke allows operators to quickly change the pusher's end position to accommodate different pallet or product sizes without mechanical rework, using the trunnion mount for a smooth arcing motion.
Wear Compensation in Clamping
For high-cycle clamping fixtures, the adjustable stroke can be used to take up slack as tooling or contact surfaces wear over time, maintaining consistent clamping force and position without replacing the entire cylinder.
Is the Airtac SCJ100 Standard Cylinder SCJ100X400-100TC the Right Cylinder?
Select the SCJ100X400-100TC when your application requires a powerful 100 mm bore actuator with a 400 mm maximum reach, but you need the flexibility to dial back the stroke end by up to 100 mm during setup. If the force requirement is lower, stepping down to an 80 mm bore (2513 N push at 0.5 MPa) can reduce air consumption and physical size. For a fixed, non-adjustable stroke, a standard SC100X400 cylinder is a simpler alternative. This cylinder is a direct replacement for another AirTAC SCJ100X400-100TC with a centre trunnion mount.
For this 400 mm stroke length, be mindful of side-loading on the piston rod. If the load is not guided and applies a lateral force, rod bending or premature seal wear can occur. Mitigate this by using an external guide rail or switching to a guided cylinder assembly to ensure the rod is loaded purely in tension and compression.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ100X400-100TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 7068 N. The pull force is lower because the 25 mm piston rod reduces the effective area on the return stroke.
Yes. This is a genuine AirTAC SCJ100X400-100TC with a centre trunnion (TC) mount and PT1/2 ports. It is a direct dimensional and performance match for another AirTAC cylinder with the same model code, magnet option, and mounting configuration.
