About the Airtac SCJ100 Standard Cylinder SCJ100X75-10S
The SCJ100X75-10S is a 100 mm bore double-acting single-rod cylinder with a rear adjusting screw that lets you fine-tune the stroke end by up to 10 mm. At 0.5 MPa it delivers 3927 N push and 3681 N pull, giving you a robust 801 kgf theoretical force class for pressing, clamping, and positioning tasks where the final stop point needs on-machine tweaking.
This model includes a built-in magnet (suffix S) so CMSG/DMSG/EMSG sensors mount directly on the tie-rod barrel for non-contact position sensing. The 25 mm diameter rod, PT1/2 port, and 29 mm air cushion are standard for the 100 mm bore. The body length A(SCJ) is 245 mm, slightly longer than the fixed-stroke SC due to the rear adjuster, and the operating range is 0.15-1.0 MPa with a standard speed of 30-800 mm/s.
Airtac SCJ100 Standard Cylinder SCJ100X75-10S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X75-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 75 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 SCJ100X75-10S Is Used
Commissioning & Setup
The 10 mm screw adjuster lets technicians dial in the exact stop position during machine commissioning without swapping cylinders or machining external hard stops.
Product Changeover
On packaging or assembly lines, quickly re-set the stroke end for different product sizes or formats, reducing changeover time and eliminating mechanical shims.
Wear Compensation
In pressing or clamping fixtures, the adjuster takes up tooling wear or material thickness variation over time, maintaining consistent force application at the new end point.
Is the Airtac SCJ100 Standard Cylinder SCJ100X75-10S the Right Cylinder?
Step up to a 125 mm bore (6136 N push at 0.5 MPa) if the load approaches the 3927 N push limit of this 100 mm unit; step down to an 80 mm bore (2513 N) for lighter, faster applications. If the stroke must be fixed and never adjusted after commissioning, the standard SC100X75 is a simpler, slightly shorter alternative. For guided loads or side forces, pair this cylinder with an external guide rail, as the 75 mm stroke on a 25 mm rod is robust but side loads should still be managed.
As a direct replacement, match the 100 mm bore, 75 mm nominal stroke, 10 mm adjust range, PT1/2 port thread, basic mounting, and the -S magnet. The SCJ mounting subset includes FA front flange, LB foot, or TC centre trunnion with TCM1 bracket (no FB flange or CA/CB clevis).
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 SCJ100X75-10S FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N (pull is lower because the 25 mm rod reduces the piston area on the return side). At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes, if you need the 10 mm field-adjustable stroke end. The SCJ100X75-10S has the same 100 mm bore, 75 mm nominal stroke, PT1/2 ports, and mounting accessories as the SC series. The body is slightly longer (A=245 mm) to house the rear adjusting screw. Ensure your machine has clearance for the extra length and that the -S magnet is matched if you use sensors.
