About the Airtac SC50 Standard Cylinder SC50X50SFA
The SC50X50SFA is a 50 mm bore, 50 mm stroke double-acting tie-rod cylinder from AirTAC. It delivers 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a strong performer for short linear moves. The rod is 20 mm diameter with an M16x1.5 male thread, and the body length A is 150 mm.
This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus a front rectangular flange (FA) for secure panel or bulkhead mounting. The adjustable air cushion at each end is 21 mm long, helping to decelerate the piston smoothly. Ports are PT1/4, and the standard seal material is TPU for operation from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X50SFA Is Used
Part Ejection
The 50 mm stroke and 982 N push force at 0.5 MPa eject small to medium stamped or molded parts from a fixture. The built-in magnet allows end-of-stroke confirmation via a reed sensor.
Short-Stroke Gate
Operates a diverter gate or stop on a conveyor line. The front flange mount bolts directly to the frame, and the adjustable cushion reduces impact noise at the end of the fast 50 mm travel.
Clamping & Pressing
Applies up to 1767 N of clamping force at 0.9 MPa for gluing, welding, or assembly fixtures. The magnetic piston enables sensor-based cycle interlocking for safety and automation control.
Is the Airtac SC50 Standard Cylinder SC50X50SFA the Right Cylinder?
Choose the SC50X50SFA when you need a compact 50 mm stroke with sensor feedback and a rigid front-flange mount. If your force requirement is lower, stepping down to a 40 mm bore reduces push force to 628 N at 0.5 MPa; for higher force, the 63 mm bore provides 1559 N at the same pressure. The short 50 mm stroke keeps the rod well-supported, but always align the load axially to avoid side-load wear.
For direct replacement, match five points: 50 mm bore, 50 mm stroke, PT1/4 port thread, front flange mount (FA, part F-SC50FA), and the built-in magnet (-S). This tie-rod cylinder is shorter than ISO 15552 types and is not dimensionally interchangeable with them.
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 SC50X50SFA FAQ
At 0.5 MPa, the cylinder provides 982 N push force and 825 N pull force. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than ISO 15552 cylinders. For a direct replacement, you must match another AirTAC SC50 tie-rod cylinder with the same 50 mm stroke, PT1/4 ports, front flange mount, and built-in magnet.
