About the Airtac SC50 Standard Cylinder SC50X1050
The AirTAC SC50X1050 is a double-acting tie-rod cylinder with a 50 mm bore and an extended 1050 mm stroke, built for applications requiring a long reach with a compact body cross-section. At 0.5 MPa it generates 982 N of push force and 825 N on the pull stroke, while the maximum operating thrust at 0.9 MPa reaches 1767 N.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 port connections. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, and the total extended body length is approximately 1200 mm. Because the 1050 mm stroke exceeds the standard maximum of 1200 mm for the 50 bore, this is a made-to-order non-standard configuration.

Where the Airtac SC50 Standard Cylinder SC50X1050 Is Used
Long-Reach Part Transfer
Pushes or pulls components across wide conveyor gaps or between distant stations, extending up to 1050 mm to bridge equipment that cannot be placed close together.
Vertical Panel Press
Applies consistent clamping pressure over a tall stroke in laminating or assembly fixtures, using the 982 N force at 0.5 MPa to hold large panels securely during curing.
Automated Sorting Gate
Operates a tall diverter gate or flipper in a material handling line, where the long 1050 mm stroke provides the necessary arc of movement to redirect packages between chutes.
Is the Airtac SC50 Standard Cylinder SC50X1050 the Right Cylinder?
Select the SC50 when your load needs roughly 1000 N of push force at standard plant pressure. If you need more force, step up to the SC63 bore which delivers 1559 N at 0.5 MPa; for a lighter, more compact solution the SC40 bore provides 628 N. For any stroke beyond 300 mm, evaluate side-load forces on the rod—at 1050 mm the unsupported rod is susceptible to bending under even minor lateral loads, so an external linear guide or a guided cylinder should be paired with this actuator.
To ensure a drop-in replacement, match five key points: 50 mm bore, 1050 mm stroke, PT1/4 port thread, basic mounting (no integral bracket), and the absence of a built-in magnet. This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X1050 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 1374 N and the pull force is approximately 825 N (based on the 0.5 MPa pull value of 825 N, which remains constant as pull force is limited by the annular piston area). For precise sizing, always use the push value for extension work.
It is not recommended. The 20 mm diameter rod extended to 1050 mm is vulnerable to bending and buckling under side loads or high acceleration. You should install an external linear guide rail or switch to a guided cylinder assembly to protect the rod bearings and ensure reliable long-term operation.
