About the Airtac SCJ100 Standard Cylinder SCJ100X80-10S
The SCJ100X80-10S is a double-acting, single-rod pneumatic cylinder that puts 3927 N of push force at your command at 0.5 MPa, driven by a 100 mm bore and a 25 mm piston rod. Its defining feature is a rear-cap adjusting screw that lets you shorten the stroke end by up to 10 mm in the field, making it invaluable for commissioning fine-tuning or taking up wear without swapping the cylinder.
This model includes a built-in magnet (the -S suffix), so you can clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for reliable end-of-stroke detection. The standard PT1/2 port threads, TPU seals, and a 29 mm air cushion ensure smooth deceleration, with a body length of 245 mm (A dimension) that fits into the same footprint as other SCJ100 cylinders.
Airtac SCJ100 Standard Cylinder SCJ100X80-10S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X80-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 80 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 SCJ100X80-10S Is Used
Commissioning & Setup
The 10 mm adjustment screw allows technicians to dial in the exact stroke end position during initial machine setup, compensating for minor assembly tolerances without re-machining any parts.
Wear Take-Up on Stops
In high-cycle clamping or pressing fixtures, the adjustable stroke can be used to compensate for wear on the tooling or workpiece contact surfaces, maintaining consistent clamping force over time.
Format Changeover
For packaging or labeling machines that handle different product sizes, the rear screw provides a quick, tool-free way to adjust the cylinder's end position for a new format, reducing changeover time.
Is the Airtac SCJ100 Standard Cylinder SCJ100X80-10S the Right Cylinder?
Choose the SCJ100 when your application needs the 3927 N push force at 0.5 MPa that a 100 mm bore delivers. If you can accept a lower force, stepping down to an 80 mm bore (2513 N push at 0.5 MPa) saves space and air consumption; for heavier loads, the 125 mm bore provides 6136 N. The 10 mm adjustable range is ideal for precise end-stop tuning, but if your process requires frequent, large stroke changes, a fixed-stroke SC cylinder with external hard stops may be a simpler choice. For a direct replacement, match this model's 100 mm bore, 80 mm nominal stroke, 10 mm adjust range, PT ports, and the -S magnet option.
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 SCJ100X80-10S FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 7854 N. The push force is always greater than the pull force because this is a single-rod cylinder.
Yes, provided the bore (100 mm), nominal stroke (80 mm), and port thread (PT) match. The SCJ body is slightly longer to house the adjustment screw, so check your available space. You must also match the mounting style and the magnet option (-S) if your application uses sensors.
