About the Airtac SCJ100 Standard Cylinder SCJ100X60-30
The SCJ100X60-30 is a 100 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end. A rear-cap adjusting screw provides a 30 mm range to fine-tune the stroke end position without removing the cylinder, ideal for commissioning and format changes. At 0.5 MPa it delivers 3927 N push force and 3681 N pull force, operating on filtered air up to 1.0 MPa.
This tie-rod cylinder uses a 25 mm diameter piston rod with an M20x1.5 rod thread and PT1/2 ports. The adjustable air cushion provides 29 mm of deceleration, and the SCJ body length A is 245 mm. It suits applications needing a robust, mid-to-heavy force actuator where the stroke end must be dialled in precisely on the machine.
Airtac SCJ100 Standard Cylinder SCJ100X60-30 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X60-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 60 mm |
| Stroke adjustment | Up to 30 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 SCJ100X60-30 Is Used
Commissioning & Setup
The 30 mm rear screw adjustment lets technicians dial in the exact stroke end position during initial machine commissioning without swapping cylinders or machining external stops.
Product Changeover
On packaging or assembly lines, operators can quickly re-set the cylinder stroke to handle different product sizes or formats, minimising downtime between batches.
Wear Compensation
In clamping or pressing fixtures, the adjustable stroke end can be advanced slightly over time to compensate for pad wear or tooling set, maintaining consistent clamping force.
Is the Airtac SCJ100 Standard Cylinder SCJ100X60-30 the Right Cylinder?
Choose this SCJ100 when you need roughly 3900 N of push force at standard plant pressure and the ability to trim the stroke end by up to 30 mm. If you require more force, step up to the 125 mm bore which provides 6136 N push at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC100 series is a simpler alternative. This model is a direct replacement for an AirTAC SCJ100X60-30 with PT ports, basic mounting, and no magnet.
For strokes of 60 mm, rod buckling is not a concern, but always ensure the load is guided to prevent side-loading on the rod bearing. If your application involves frequent stroke-end adjustment, the SCJ design eliminates the need for external hard stops, saving setup time.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ100X60-30 FAQ
At 0.5 MPa air pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The pull force is lower due to the area of the 25 mm piston rod.
You can replace an SC100 with an SCJ100 if you need the adjustable stroke feature, but you must match the bore, nominal stroke, port type, and mounting. The SCJ body is slightly longer to house the adjusting screw. This SCJ100X60-30 directly replaces another AirTAC SCJ100X60-30 with PT ports and basic mounting.
