About the Airtac SCJ100 Standard Cylinder SCJ100X95-30S
The SCJ100X95-30S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the 95 mm nominal stroke by up to 30 mm without removing the unit. Its 100 mm bore delivers 3927 N of push force at 0.5 MPa, making it a powerful choice for pressing, clamping, and heavy-duty positioning tasks where the final stroke length must be dialed in during commissioning.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, eliminating the need for external switch brackets. The 25 mm piston rod and PT1/2 ports handle high flow, while the 29 mm air cushion decelerates the load smoothly at stroke end. The rear adjusting screw sets the stroke end position within the 30 mm range—it is not a force or speed regulator.
Airtac SCJ100 Standard Cylinder SCJ100X95-30S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X95-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 95 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 SCJ100X95-30S Is Used
Commissioning & Setup
Dial in the exact 95 mm end position during machine bring-up without fabricating custom stops. The 30 mm adjustment range lets technicians quickly compensate for stack-up tolerances in welded assemblies.
Product Changeover
On packaging lines handling different box sizes, the adjustable stroke allows operators to reset the pusher's end point for a new format in seconds, minimizing downtime between production runs.
Heavy-Duty Clamping
In a woodworking or metal fab jig, the 3927 N push force at 0.5 MPa securely holds large workpieces. The stroke can be fine-tuned to prevent over-travel that could damage delicate surface finishes.
Is the Airtac SCJ100 Standard Cylinder SCJ100X95-30S the Right Cylinder?
Choose the SCJ100X95-30S when you need a robust 100 mm bore cylinder with 95 mm of travel that can be shortened on the machine by up to 30 mm. If your 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 applications needing a fixed, non-adjustable stroke, the standard SC series is a simpler and more economical alternative.
This cylinder is a direct replacement for an existing AirTAC SCJ100X95-30S with a magnet, PT ports, and basic mounting. For strokes of 95 mm, the rod is well-supported within the bearing, but if your application involves significant side loads, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending and premature seal wear.
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 SCJ100X95-30S FAQ
At the standard operating pressure of 0.5 MPa, this cylinder delivers 3927 N of push force and 3681 N of pull force. The push force is higher because it acts on the full 100 mm bore area, while the pull force is reduced by the area of the 25 mm piston rod. The maximum push force at 0.9 MPa is 7068 N.
Yes, it is a direct form-and-function match for any AirTAC SCJ100 cylinder with a 95 mm nominal stroke, a 30 mm adjustment range, a built-in magnet, PT ports, and basic (no bracket) mounting. Ensure your existing sensor type is compatible with the integrated magnet. This cylinder will not directly interchange with fixed-stroke SC models or ISO 15552 cylinders.
