About the Airtac SCJ50 Standard Cylinder SCJ50X200-100S
The SCJ50X200-100S provides a nominal 200 mm stroke with a 100 mm rear adjusting screw, letting you fine-tune the stroke end on the fly without swapping the cylinder. With a 20 mm rod and PT1/4 ports, it delivers 982 N of push force at 0.5 MPa, scaling up to 1767 N at the 0.9 MPa maximum operating pressure.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors for reliable end-of-stroke detection. The tie-rod construction and 21 mm air cushion ensure smooth deceleration, making it a practical choice for commissioning and format-change applications where the final stop position needs frequent adjustment.
Airtac SCJ50 Standard Cylinder SCJ50X200-100S Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X200-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 200 mm |
| Stroke adjustment | Up to 100 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 21 mm |
| Max stroke | Up to 1200 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCJ50 Standard Cylinder SCJ50X200-100S Is Used
Commissioning Fine-Tuning
Dial in the exact end-stop position during machine setup without needing to machine custom spacers or swap cylinders, saving hours of trial and error.
Product Format Changeover
Quickly adjust the stroke end to accommodate different product sizes on a packaging line, reducing downtime between batch runs.
Wear Compensation
Extend the effective stroke slightly over time to compensate for mechanical wear in tooling or grippers, maintaining consistent part engagement.
Is the Airtac SCJ50 Standard Cylinder SCJ50X200-100S the Right Cylinder?
Choose the SCJ50X200-100S when you need to dial in a precise end position within a 100 mm window. If 982 N of push force is insufficient, stepping up to the SCJ63 series provides 1559 N at the same 0.5 MPa pressure. For applications that do not require field adjustability, the fixed-stroke SC50X200 is a simpler, more compact alternative. To replace this unit, match the 50 mm bore, 200 mm nominal stroke, 100 mm adjust range, PT1/4 threads, and the -S magnet option. For strokes over 300 mm, consider an external guide to protect the 20 mm rod from side loads.
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 SCJ50 Standard Cylinder SCJ50X200-100S FAQ
At 0.5 MPa, it generates 982 N pushing and 825 N pulling. The force increases with pressure, reaching 1767 N push at the 0.9 MPa maximum operating limit.
A screw in the rear cap lets you shorten the stroke end by up to 100 mm. The 200 mm in the model code is the maximum nominal stroke; the screw only limits how far the piston extends, it does not change the cylinder's force or speed.
