About the Airtac SC50 Standard Cylinder SC50X70N
The SC50X70N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 70 mm stroke, it features a 20 mm diameter piston rod with an M16x1.5 thread and PT1/4 ports, making it a robust choice for medium-duty linear actuation.
This model is specified with NBR (nitrile) seals, offering reliable performance in standard industrial environments. The cylinder body has a length of 150 mm, and the adjustable pneumatic cushion at each end, with a cushion length of 21 mm, decelerates the piston smoothly to reduce end-of-stroke impact.

Where the Airtac SC50 Standard Cylinder SC50X70N Is Used
Material Sorting Gates
The 982 N push force at standard line pressure is ideal for actuating diverter gates on conveyor systems, reliably redirecting packages or materials in logistics hubs.
Clamping & Holding Fixtures
Provides consistent, controlled force for pneumatic clamping in CNC machining or welding fixtures, holding workpieces securely during automated processes.
Agricultural Implement Control
Used to actuate levers and chutes on farming equipment like seed drills or fertilizer spreaders, where the NBR seals handle typical outdoor lubricants and temperatures.
Is the Airtac SC50 Standard Cylinder SC50X70N the Right Cylinder?
For applications requiring slightly more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N of push force at 0.5 MPa. If space is a constraint and less force is acceptable, the 40 mm bore SC40 series delivers 628 N. To ensure a correct replacement, match all five critical points: the 50 mm bore, 70 mm stroke, PT port thread, the basic mounting configuration, and the absence of a built-in magnet. While the SC series is a tie-rod cylinder and not dimensionally interchangeable with ISO 15552 profiles, it is a direct replacement for another AirTAC SC50 cylinder with the same specifications.
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 SC50X70N FAQ
The theoretical push force is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and reaches a maximum of 1767 N at the 0.9 MPa operating limit. The pull force on the return stroke is 825 N at 0.5 MPa due to the area of the 20 mm rod.
Yes, it is mechanically identical. The NBR seal variant is a direct functional replacement for a TPU-seal SC50X70 in the same mounting configuration. Ensure your operating temperature stays within the standard -20 to +70 °C range, as NBR has similar limits to the default TPU material.
