About the Airtac SCJ100 Standard Cylinder SCJ100X300-10
The SCJ100X300-10 delivers a robust 3927 N push force at 0.5 MPa from its 100 mm bore, making it a workhorse for applications needing substantial power with a 300 mm nominal stroke. Its key differentiator is the rear-cap adjusting screw, which provides a 10 mm field-adjustable range to fine-tune the stroke end position without removing the cylinder, ideal for commissioning and wear take-up.
This double-acting, single-rod cylinder uses a 25 mm diameter rod and PT1/2 ports, with an adjustable air cushion for smooth deceleration. The tie-rod construction and 29 mm cushion length ensure reliable, repeatable stopping. At the maximum operating pressure of 0.9 MPa, it generates a push force of 7068 N, giving you a significant power reserve for demanding clamping or pressing tasks.
Airtac SCJ100 Standard Cylinder SCJ100X300-10 Technical Specifications

| 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 |

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 SCJ100X300-10 Is Used
End-Stop Fine-Tuning
The 10 mm rear adjustment screw allows operators to dial in the exact stop position on a press or clamping fixture, compensating for variations in part thickness or tooling wear without needing to reprogram a controller.
Product Changeover
On a packaging line, the adjustable stroke lets you quickly change the pusher's end position to handle a new box size. The 3927 N push force at 0.5 MPa easily manages heavy cartons, and the 10 mm range covers typical format differences.
Commissioning Trials
During machine setup, the SCJ100X300-10 allows engineers to experimentally determine the optimal 300 mm stroke end point. The 7068 N force at 0.9 MPa provides ample power for testing under full load, and the setting can be locked in once the ideal position is found.
Is the Airtac SCJ100 Standard Cylinder SCJ100X300-10 the Right Cylinder?
For a step up in force, the 125 mm bore SCJ offers 6136 N of push at 0.5 MPa. If your application requires a fixed, non-adjustable stroke, the standard SC100X300 is the direct alternative. To ensure a correct replacement, match the 100 mm bore, 300 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting configuration. For this 300 mm stroke, be mindful of side loads which can cause rod bending; if lateral forces are present, use an external guide rail or consider a guided cylinder assembly to protect the rod and seals.
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 SCJ100X300-10 FAQ
As a single-rod cylinder, push and pull forces differ. At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
The SCJ has a rear-cap adjusting screw that shortens the stroke end position by up to 10 mm. This allows you to fine-tune the stop point in the field for tasks like wear compensation or format changes. A fixed-stroke SC cylinder has a non-adjustable stroke length. If you don't need this field adjustability, the SC100X300 is the equivalent fixed-stroke model.
