About the Airtac SCJ100 Standard Cylinder SCJ100X275-10S
The SCJ100X275-10S is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides up to 10 mm of field-adjustable stroke-end reduction. With a 100 mm bore, it delivers a substantial 3927 N of push force at 0.5 MPa, making it a powerful actuator for heavy industrial tasks where the final stop position needs fine-tuning during commissioning or changeovers.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise end-of-stroke detection. The cylinder uses a 25 mm diameter piston rod, PT 1/2 ports, and a 29 mm air cushion to decelerate the piston quietly, with a body length A(SCJ) of 245 mm.
Airtac SCJ100 Standard Cylinder SCJ100X275-10S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X275-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 275 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 SCJ100X275-10S Is Used
Commissioning & Setup
Engineers can fine-tune the stroke end by up to 10 mm on the machine without swapping cylinders, speeding up the initial setup of pressing or clamping stations.
Wear Compensation
In high-cycle material handling, the adjustable screw can take up mechanical slack or compensate for tooling wear over time, maintaining consistent part contact.
Format Changeovers
Quickly adapt the cylinder's end position for different product sizes in packaging or assembly lines, reducing downtime between batches.
Is the Airtac SCJ100 Standard Cylinder SCJ100X275-10S the Right Cylinder?
Choose the SCJ100X275-10S when your application requires a powerful push in a 275 mm stroke but also demands the ability to dial in the exact end position within a 10 mm window. If 3927 N of push force at 0.5 MPa is more than needed, stepping down to an 80 mm bore reduces push force to 2513 N; if it is insufficient, the 125 mm bore provides 6136 N. For applications where the stroke is fixed and never needs adjustment, the standard SC100X275-S fixed-stroke cylinder is a more economical alternative. This cylinder is a direct replacement for another AirTAC SCJ100X275-10S with PT ports, a basic mount, and a magnet. At a 275 mm stroke, ensure the load is guided to prevent excessive side-loading on the rod and bearings.
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 SCJ100X275-10S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N (due to the 25 mm rod area). At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N.
Yes, this is a direct replacement for any AirTAC SCJ100 cylinder with a 275 mm nominal stroke, a 10 mm adjustable range, PT ports, a basic mount, and a built-in magnet. Verify your existing port thread and mounting style match.
