About the Airtac SCJ100 Standard Cylinder SCJ100X800-100S
The AirTAC SCJ100X800-100S is a double-acting, single-rod pneumatic cylinder engineered for applications requiring precise, field-adjustable stroke end positioning. With a 100 mm bore and an 800 mm nominal stroke, this model provides a substantial 100 mm rear-screw adjustment range, allowing operators to fine-tune the stroke end without removing the cylinder or adding external hard stops. It delivers a powerful 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa, making it suitable for heavy-duty linear actuation.
This unit features a built-in magnet (-S suffix), enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable end-of-stroke detection. The 25 mm diameter piston rod and PT1/2 port connections ensure robust air flow, while the 29 mm air cushion at each end provides smooth, controlled deceleration. The body length A(SCJ) is 245 mm, providing a compact footprint for its force class.
Airtac SCJ100 Standard Cylinder SCJ100X800-100S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X800-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 800 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 SCJ100X800-100S Is Used
Commissioning & Setup
Ideal for commissioning new automation lines where the final stroke end position must be dialed in precisely under live load conditions, saving hours of mechanical shimming.
Format Changeovers
Quickly adapt to different product sizes on packaging or material handling systems by adjusting the cylinder stroke end with a simple screw turn, minimizing changeover downtime.
Wear Compensation
In high-cycle clamping or pressing operations, use the 100 mm adjustment to compensate for tooling wear over time, maintaining consistent clamping force and part quality.
Is the Airtac SCJ100 Standard Cylinder SCJ100X800-100S the Right Cylinder?
Select the SCJ100X800-100S when your application demands a powerful 100 mm bore with the flexibility to adjust the stroke end by up to 100 mm on the fly. If your force requirements are lower, stepping down to the 80 mm bore reduces push force to 2513 N at 0.5 MPa; for higher demands, the 125 mm bore provides 6136 N. For a fixed stroke without adjustability, the standard SC series is a direct alternative. As a direct replacement, match the 100 mm bore, 800 mm nominal stroke, 100 mm adjust range, PT port thread, and the integrated magnet sensor option. For this 800 mm stroke, ensure the rod is supported against side loads if not guided externally.
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 SCJ100X800-100S FAQ
At 0.5 MPa, it delivers 3927 N pushing and 3681 N pulling due to the single-rod design. Maximum push force at 0.9 MPa operating pressure is 7068 N.
A rear-cap adjusting screw limits the piston's retract stroke end. Turning the screw changes the stop position within a 100 mm range, allowing fine-tuning without changing the cylinder's nominal 800 mm rating.
