About the Airtac SCJ100 Standard Cylinder SCJ100X350-100S
The SCJ100X350-100S is a double-acting, single-rod pneumatic cylinder with a 100mm bore and a nominal stroke of 350mm, featuring a rear-cap adjusting screw that provides a 100mm field-adjustable range. This allows precise fine-tuning of the stroke end position without replacing the cylinder, delivering a push force of 3927 N at 0.5 MPa and up to 7068 N at 0.9 MPa.
Equipped with a built-in magnet (-S suffix), this model is ready for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors for reliable end-of-stroke detection. The cylinder uses a 25mm diameter piston rod, PT1/2 port threads, and a standard TPU seal suitable for operating temperatures from -20 to +70°C. Its tie-rod construction provides a robust body length A of 245 mm.
Airtac SCJ100 Standard Cylinder SCJ100X350-100S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X350-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 350 mm |
| Stroke adjustment | Up to 100 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 SCJ100X350-100S Is Used
Commissioning & Setup
The 100mm adjustment range lets technicians fine-tune the end-stop position on a new assembly line without machining custom stops, speeding up initial machine setup and debugging.
Format Changeovers
On packaging or material handling systems, quickly adjust the stroke end to accommodate different product sizes or pallet dimensions, minimizing downtime between production runs.
Wear Compensation
In high-cycle pressing or clamping fixtures, the adjustable screw can be periodically advanced to take up mechanical wear on tooling or seals, maintaining consistent clamp force and part quality.
Is the Airtac SCJ100 Standard Cylinder SCJ100X350-100S the Right Cylinder?
Choose the SCJ100X350-100S when you need a substantial 3927 N push force at standard line pressure and the ability to dial in the stroke end by up to 100mm during commissioning or changeovers. If your force requirement is lower, stepping down to an 80mm bore SCJ reduces push force to 2513 N at 0.5 MPa, saving space and air consumption. For applications needing a fixed, unchangeable stroke, the standard SC series is a more economical choice that omits the rear adjustment mechanism.
For this 350mm stroke, be mindful of side loads which can cause rod bending; an external guide rail or switching to a guided cylinder is recommended if the load is not perfectly axial. As a direct replacement, match this model to another SCJ100X350-100S cylinder with a PT port, basic mounting, and the -S magnet option to ensure identical form, fit, and function.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ100X350-100S FAQ
At 0.5 MPa operating pressure, the cylinder provides a push force of 3927 N and a pull force of 3681 N. The maximum push force at the 0.9 MPa rating is 7068 N. The pull force is lower due to the area of the 25mm piston rod.
A rear-cap screw lets you shorten the stroke end position by up to 100mm from the 350mm nominal maximum. It is a mechanical end-stop adjustment, not a locking device. The piston will drift if air pressure is lost; for load holding without pressure, you must add an external rod lock or pilot-operated check valve.
