About the Airtac SCJ100 Standard Cylinder SCJ100X40-10
The SCJ100X40-10 is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides a 10 mm field-adjustable stroke end, letting you fine-tune the piston stop position without replacing the cylinder. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa, making it a powerful actuator for pressing, clamping, and heavy-duty positioning tasks where the final stroke length must be dialed in precisely on the machine.
This model features a 25 mm diameter piston rod, PT1/2 ports, and a 29 mm air cushion for smooth end-of-stroke deceleration. The SCJ body length is 245 mm, slightly longer than a fixed-stroke SC to accommodate the adjustment mechanism. It operates on filtered air from 0.15 to 1.0 MPa and is built with a standard TPU seal for a temperature range of -20 to +70 °C.
Airtac SCJ100 Standard Cylinder SCJ100X40-10 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X40-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 40 mm |
| Stroke adjustment | Up to 10 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 SCJ100X40-10 Is Used
End-Stop Commissioning
Fine-tune the final position of a heavy pressing tool during initial machine setup. The 10 mm adjustment screw allows operators to dial in the exact stroke end for perfect part contact without mechanical stops.
Wear Compensation
Automatically compensate for brake pad or friction material wear in a heavy-duty clamping fixture. The adjustable stroke end can be periodically reset to maintain consistent clamping force as consumable parts thin out.
Product Format Changeover
Quickly adapt a reject station on a packaging line to handle different box sizes. The 10 mm adjustment range lets a technician change the pusher's stop point in seconds without swapping the cylinder.
Is the Airtac SCJ100 Standard Cylinder SCJ100X40-10 the Right Cylinder?
This 100 mm bore cylinder is a high-force workhorse; if your application requires even greater push force, stepping up to the 125 mm bore SCJ (6136 N at 0.5 MPa) is the logical path. For lower force requirements, the 80 mm bore model provides 2513 N at 0.5 MPa and a more compact footprint. The SCJ is the right choice when you need to commission a machine, compensate for tooling wear, or accommodate different product formats by adjusting the stroke end on the fly—a fixed-stroke SC cannot offer this flexibility. For a direct replacement, match the 100 mm bore, 40 mm nominal stroke, 10 mm adjustment range, PT1/2 ports, and basic mounting style.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ100X40-10 FAQ
At the standard operating pressure of 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. The push force is higher because the single piston rod reduces the effective area on the return stroke. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 7068 N.
Yes, provided the bore, nominal stroke, port type, and mounting match. The SCJ100X40-10 has the same 100 mm bore and 40 mm nominal stroke as an SC100X40, but its body is slightly longer to house the rear adjustment screw. The 10 mm adjustment range allows you to shorten the stroke end, a feature a standard SC cylinder does not have.
