About the Airtac SCJ100 Standard Cylinder SCJ100X600-100S
The SCJ100X600-100S is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides up to 100 mm of field-adjustable stroke-end reduction. With a 100 mm bore, it delivers 3927 N of push force at 0.5 MPa and a substantial 7068 N at 0.9 MPa, making it a powerful actuator for heavy-duty positioning tasks where the exact stroke length must be fine-tuned during commissioning or changeover.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel for precise end-of-stroke detection. The 25 mm diameter piston rod and PT1/2 port ensure robust air flow, while the adjustable air cushion decelerates the 600 mm nominal stroke smoothly. The body length A for this SCJ series is 245 mm, providing a compact footprint relative to its force output.
Airtac SCJ100 Standard Cylinder SCJ100X600-100S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X600-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 600 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 SCJ100X600-100S Is Used
Multi-Product Palletizing
A palletizer handling different box heights uses the 100 mm adjustment range to quickly reset the pusher stroke end for each product format, eliminating manual stop repositioning.
Heavy-Part Clamping & Gauging
In a welding fixture for large fabrications, the adjustable stroke allows fine-tuning the clamp's final position to accommodate part tolerances, with the 3927 N force ensuring a secure hold.
Commissioning Large Automation Cells
During the setup of a new assembly line, the 100 mm screw adjustment lets integrators precisely dial in the 600 mm stroke's end point for a transfer shuttle without swapping cylinders.
Is the Airtac SCJ100 Standard Cylinder SCJ100X600-100S the Right Cylinder?
Choose the SCJ100X600-100S when you need a 600 mm stroke with the flexibility to shorten it by up to 100 mm on the machine. If your force requirement is lower, stepping down to an 80 mm bore reduces push force to 2513 N at 0.5 MPa. For applications needing a fixed, unchangeable stroke, the standard SC series is a simpler alternative. This cylinder is a direct replacement for another AirTAC SCJ100X600-100S with a PT port and magnet.
For a 600 mm stroke, consider the potential for side loading on the 25 mm rod. If the load is not guided externally, the rod may be subject to bending moments. In such cases, use an external guide rail or switch to a guided cylinder assembly to protect the rod bearings and ensure long service life.
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 SCJ100X600-100S FAQ
As a single-rod cylinder, push and pull forces differ. At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The maximum push force at the 1.0 MPa operating limit is 7068 N.
Yes, if you need the ability to fine-tune the stroke end. The SCJ100X600-100S matches the 100 mm bore and 600 mm nominal stroke of an SC100X600, but adds a rear screw to shorten the stroke by up to 100 mm. Ensure your mounting and porting (PT1/2) are compatible.
