About the Airtac SC50 Standard Cylinder SC50X175FA
The SC50X175FA is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 50 mm bore and 175 mm stroke suit medium-force clamping, pressing, and material-transfer tasks where a compact tie-rod body is preferred.
This model is factory-configured with an FA front rectangular flange (part F-SC50FA) for rigid panel or bulkhead mounting. The 20 mm diameter piston rod and PT1/4 ports provide reliable flow, while the adjustable air cushion at each end decelerates the 175 mm stroke smoothly. The body length A is 150 mm, giving a total extended length of approximately 325 mm.

Where the Airtac SC50 Standard Cylinder SC50X175FA Is Used
Panel-Mounted Clamping
The FA front flange bolts directly to a machine bulkhead, allowing the 50 mm bore cylinder to apply 1767 N of clamping force at 0.9 MPa for CNC fixture or welding-jig actuation.
Part Stops & Diverters
With 982 N of push at standard shop air, the SC50X175FA powers a robust conveyor gate or diverter arm, handling medium-weight packages in sorting lines.
Small Press Tools
The 175 mm stroke and 20 mm rod diameter suit a light assembly press or staking tool, where the adjustable cushion protects tooling from impact at end of stroke.
Is the Airtac SC50 Standard Cylinder SC50X175FA the Right Cylinder?
Choose the SC50 when 982 N at 0.5 MPa fits the load; for more force step up to the SC63 (1559 N at 0.5 MPa), or down to the SC40 (628 N) for lighter, faster cycles. This 175 mm stroke is well within the 1200 mm maximum standard stroke for bore 50.
For exact replacement, match five points: 50 mm bore, 175 mm stroke, PT1/4 ports, FA front flange mount, and the absence of a magnet. This cylinder is not ISO 15552 interchangeable; it replaces another AirTAC SC50 tie-rod unit with the same configuration.
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 SC50X175FA FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length differ. It directly replaces another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT ports, and FA front flange mount.
