About the Airtac SCJ50 Standard Cylinder SCJ50X60-50SLB
The SCJ50X60-50SLB is a double-acting, single-rod pneumatic cylinder that puts field-adjustable stroke control directly in your hands. Its rear-cap adjusting screw provides a generous 50 mm of fine-tuning range, letting you dial in the exact stroke end position from 10 mm up to the nominal 60 mm maximum. This 50 mm bore cylinder delivers a substantial 982 N of push force at 0.5 MPa, making it a strong performer for mid-range automation tasks.
This model comes factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. It also includes an LB-style axial foot mount (F-SC50LB) for secure surface installation. The 20 mm piston rod and PT1/4 ports ensure solid mechanical connection and ample air flow, while the adjustable air cushion decelerates the 50 mm bore piston smoothly at the end of its travel.
Airtac SCJ50 Standard Cylinder SCJ50X60-50SLB Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X60-50SLB |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 60 mm |
| Stroke adjustment | Up to 50 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 SCJ50X60-50SLB Is Used
Format Changeover
Quickly adjust the end stop for different product sizes on a packaging line without tools, using the 50 mm adjustment range to switch between box heights in minutes.
Commissioning & Setup
Fine-tune the actuator's stroke end during machine commissioning to perfectly align with mating tooling, eliminating the need to shim or modify hard stops.
Wear Compensation
Periodically adjust the stroke end to compensate for mechanical wear in grippers or linkages, maintaining precise operation over the machine's lifecycle.
Is the Airtac SCJ50 Standard Cylinder SCJ50X60-50SLB the Right Cylinder?
Choose the SCJ50X60-50SLB when your application requires a robust mid-bore cylinder with the ability to fine-tune the stroke end without replacing the unit. If 982 N of push force at 0.5 MPa is insufficient, stepping up to the 63 mm bore provides 1559 N. For applications needing a fixed, non-adjustable stroke, the standard SC series is a more economical choice. This model is a direct replacement for any AirTAC SCJ cylinder with a 50 mm bore, 60 mm nominal stroke, a 50 mm adjust range, PT ports, an LB foot mount, and a magnet sensor. For strokes of 300 mm or more, evaluate the rod bearing load and consider an external guide to prevent rod bending under high side loads.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ 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 SCJ50X60-50SLB FAQ
At 0.5 MPa, it provides 982 N of push force and 825 N of pull force. The maximum push force at the 0.9 MPa operating limit is 1767 N.
No. Like all standard pneumatic cylinders, the SCJ will not hold its position if air pressure is exhausted or lost. The adjusting screw only sets the stroke end position and does not act as a mechanical lock. For load holding, you must add an external rod brake or a pilot-operated check valve.
