About the Airtac SCJ100 Standard Cylinder SCJ100X260-100S
The SCJ100X260-100 is a double-acting, single-rod pneumatic cylinder that provides a nominal 260 mm stroke, field-adjustable by up to 100 mm via a rear-cap screw. This allows machine builders to fine-tune the stroke end position without swapping the cylinder or adding external hard stops. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa, while the pull force is 3681 N at 0.5 MPa due to the 25 mm piston rod.
The built-in magnet (suffix -S) lets you clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for reliable end-of-stroke sensing. The cylinder uses PT1/2 ports, has a 29 mm adjustable air cushion, and a body length A of 245 mm. It is part of the AirTAC SCJ family, a tie-rod design that is not dimensionally interchangeable with ISO 15552 profiles, ensuring you get a genuine replacement that matches your existing SCJ100 setup.
Airtac SCJ100 Standard Cylinder SCJ100X260-100S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X260-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 260 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 SCJ100X260-100S Is Used
Multi-Product Assembly Jigs
The 100 mm adjust range allows a single jig to accommodate different product heights by quickly turning the rear screw, eliminating the need for mechanical shims during changeovers.
Wear Take-Up on Clamping Stations
As gripper pads or tooling wear down, the stroke end can be extended in fine increments to maintain consistent clamping pressure without reprogramming the PLC.
Commissioning of Press-Fit Operations
During initial setup, the 100 mm adjustable stroke lets engineers empirically find the optimal press depth, then lock the screw for repeatable 7068 N push cycles at full pressure.
Is the Airtac SCJ100 Standard Cylinder SCJ100X260-100S the Right Cylinder?
Choose the SCJ100X260-100 when you need a robust 100 mm bore actuator with a stroke that must be dialled in precisely on the machine. If 3927 N of push force at 0.5 MPa is more than your application requires, stepping down to an SCJ80 (2513 N push at 0.5 MPa) can reduce air consumption and physical size. For applications needing a fixed, non-adjustable stroke, the standard SC100 series is a simpler alternative. This model is a direct replacement for another AirTAC SCJ100 cylinder with a 260 mm nominal stroke, 100 mm adjust range, PT ports, and a magnet. For strokes of 300 mm or more, always check for side-loading on the 25 mm rod; an external guide rail or a guided cylinder is recommended to prevent rod bending and premature seal wear.
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 SCJ100X260-100S FAQ
At 0.5 MPa, it generates 3927 N pushing and 3681 N pulling. The maximum push force at the 1.0 MPa operating limit is 7068 N. The rear adjusting screw only changes the stroke end position; it does not alter the cylinder's output force.
Yes, this is a direct dimensional and functional replacement for any AirTAC SCJ100 with a 260 mm nominal stroke, a 100 mm adjustment range, PT1/2 ports, and a magnet. Ensure your mounting style matches; this is a basic (no bracket) configuration.
