About the Airtac SCJ50 Standard Cylinder SCJ50X60-10
The SCJ50X60-10 is a double-acting, single-rod pneumatic cylinder that puts field-adjustable stroke control directly on the machine. A rear-cap adjusting screw lets you shorten the stroke end by up to 10 mm, making it ideal for commissioning tweaks, format changeovers, or taking up wear without swapping the cylinder. The 50 mm bore delivers a useful 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), while the 20 mm rod diameter provides solid rigidity for push applications.
This tie-rod cylinder uses a PT1/4 port and an M16x1.5 rod thread, with an adjustable air cushion that decelerates the piston over the final 21 mm of travel to reduce end-cap impact. The body length A is 194 mm, and the standard stroke range for this bore extends up to 1200 mm. The 60 mm nominal stroke with a 10 mm adjustment window is a practical choice for applications where the final stop position needs a small, repeatable offset from the cylinder's full extension.
Airtac SCJ50 Standard Cylinder SCJ50X60-10 Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X60-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 60 mm |
| Stroke adjustment | Up to 10 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 SCJ50X60-10 Is Used
Commissioning & Setup
During machine commissioning, the 10 mm adjustment screw allows engineers to dial in the exact end-stop position without fabricating shims or external hard stops, speeding up the setup process.
Wear Take-Up
In clamping or pressing fixtures where tooling surfaces wear over time, the adjustable stroke end can be periodically tweaked to maintain consistent contact pressure and part quality.
Product Changeover
For packaging or assembly lines that run multiple product sizes, operators can quickly adjust the cylinder stroke to match a new format, reducing changeover time compared to swapping fixed-stroke cylinders.
Is the Airtac SCJ50 Standard Cylinder SCJ50X60-10 the Right Cylinder?
Step up to the SCJ63X60-10 if you need more force—the 63 mm bore provides 1559 N push at 0.5 MPa, a 59% increase. Step down to the SCJ40X60-10 for a lighter, more compact package at 628 N push. This SCJ model is the right pick when you need to fine-tune the stroke end position; if your application requires a fixed, repeatable stroke without adjustment, the standard SC50X60 fixed-stroke cylinder is a simpler and more cost-effective alternative. For a direct replacement, match the 50 mm bore, 60 mm nominal stroke, 10 mm adjustment range, PT1/4 ports, and basic mounting. The stroke is under 300 mm, so rod buckling is not a primary concern for axial loads.
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 SCJ50 Standard Cylinder SCJ50X60-10 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N (the difference is due to the 20 mm rod reducing the piston area on the return side). At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The adjusting screw does not alter the force output.
It is a direct dimensional match for another AirTAC SCJ50X60-10 adjustable-stroke cylinder. To replace a fixed-stroke SC50X60, you must verify that the slightly longer SCJ body length and the rear adjusting screw fit within your machine's envelope and that an adjustable stroke end is functionally acceptable for your process.
