About the Airtac SCJ100 Standard Cylinder SCJ100X65-10
The SCJ100X65-10 is a double-acting, single-rod pneumatic cylinder from the AirTAC SCJ family, featuring a rear-cap adjusting screw that provides up to 10 mm of field-adjustable stroke reduction. This allows fine-tuning of the end position without replacing the cylinder or adding external hard stops. With a 100 mm bore, it delivers a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa), making it a powerful actuator for heavy-duty positioning tasks.
This model uses a 25 mm diameter piston rod with an M20x1.5 rod thread and PT1/2 port connections. The built-in air cushion is 29 mm long, providing smooth deceleration at the stroke end. The body length A(SCJ) is 245 mm, and the standard operating speed range is 30-800 mm/s. As a genuine AirTAC component, it is built for reliable, long-life industrial service with air filtered to 40 µm.
Airtac SCJ100 Standard Cylinder SCJ100X65-10 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X65-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 65 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 SCJ100X65-10 Is Used
End-Stop Calibration
Perfect for commissioning automated lines where the final position of a heavy tool or clamp must be precisely dialed in. The 10 mm adjustment screw allows operators to compensate for assembly tolerances without machining new brackets.
Heavy Part Stops
Used as an adjustable end-stop on gravity or powered conveyors for pallets weighing up to 400 kg. The stroke can be fine-tuned to handle different product sizes, and the 3927 N push force at 0.5 MPa ensures the stop holds firmly.
Press-Fit Depth Control
Ideal for controlling the insertion depth in bearing or bushing press-fit stations. The rear adjusting screw provides a quick, tool-free method to change the final press depth within a 10 mm window for different assembly batches.
Is the Airtac SCJ100 Standard Cylinder SCJ100X65-10 the Right Cylinder?
Select the SCJ100X65-10 when you need a powerful actuator with the ability to dial in the exact stroke end position during commissioning or for format changes. If your application requires more force, stepping up to the 125 mm bore provides 6136 N of push force at 0.5 MPa. For a simpler, fixed-stroke solution where adjustability is not needed, the standard SC100 series is a direct alternative. This SCJ model is a direct replacement for any AirTAC SCJ100X65-10 with PT ports and basic mounting; ensure the adjustable range of 10 mm matches your machine's requirement.
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 SCJ100X65-10 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The maximum push force at 0.9 MPa is 7068 N. Because this is a single-rod cylinder, the push force is always greater than the pull force due to the area of the 25 mm rod.
Yes, you can replace an SC100 with a similar stroke if you need the 10 mm adjustable feature. The SCJ100 body is slightly longer (A=245 mm) to accommodate the adjusting screw. Ensure the port size (PT1/2), rod thread (M20x1.5), and mounting style match your current setup.
