About the Airtac SC50 Standard Cylinder SC50X150SN
The SC50X150SN is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 150 mm stroke and a 20 mm diameter piston rod, it is well-suited for medium-force clamping, pressing, and ejecting tasks in industrial automation.
This model includes a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke detection without external brackets. The NBR (nitrile) seals (suffix -N) provide reliable performance within the standard temperature range of -20 to +70 °C, making it a cost-effective choice for general-purpose applications.

Where the Airtac SC50 Standard Cylinder SC50X150SN Is Used
Automated Sorting Gates
The built-in magnet and NBR seals make this cylinder ideal for high-cycle diverter gates on conveyor lines, where CMSG sensors confirm gate position for reliable product sorting.
Medium-Force Clamping
Delivering 1767 N at 0.9 MPa, it provides consistent clamping pressure for CNC jigs and welding fixtures, with sensor feedback ensuring the clamp is fully engaged before a cycle starts.
Case Packing & Palletizing
Used in case erectors and palletizers for product pushing and squaring, the 150 mm stroke and integrated position sensing help maintain high throughput and accurate placement.
Is the Airtac SC50 Standard Cylinder SC50X150SN the Right Cylinder?
For applications requiring more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If lower force and a more compact body are needed, the 40 mm bore SC40 series offers 628 N. The 150 mm stroke is well within the 1200 mm maximum standard stroke for a 50 mm bore, ensuring standard lead times.
To ensure a drop-in replacement, match five key points: 50 mm bore, 150 mm stroke, PT port thread, the NBR seal material, and the built-in magnet for sensor compatibility. This is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a direct interchange for those types.
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 SC50X150SN FAQ
The theoretical push force at 0.5 MPa is 982 N, and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. These values are based on a 50 mm bore and a 20 mm rod.
No, the SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. For a direct replacement, match the bore, stroke, port thread, mounting, and magnet option to another AirTAC SC tie-rod cylinder.
