About the Airtac SC50 Standard Cylinder SC50X175N
The SC50X175N is a double-acting pneumatic cylinder with a 50 mm bore and 175 mm stroke, built in AirTAC's proven SC tie-rod series. It generates 982 N of push force and 825 N of pull force when supplied with 0.5 MPa air, stepping up to 1767 N at the maximum operating pressure of 0.9 MPa.
This model is fitted with NBR (nitrile) seals as standard for the SC family's -20 to +70 °C temperature range. The 20 mm diameter piston rod and PT1/4 port ensure reliable cycling, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly. The body length A is 150 mm, giving a total extended length of approximately 325 mm.

Where the Airtac SC50 Standard Cylinder SC50X175N Is Used
Part Transfer
Moves components between conveyor lanes or workstations with a 175 mm linear stroke, using the 825 N pull force for retraction strokes.
Clamping & Holding
Applies up to 1767 N of clamping force at 0.9 MPa to secure workpieces during machining or assembly, with NBR seals for standard shop air.
Press-Fit Assembly
Delivers a controlled 982 N push at 0.5 MPa for inserting bearings, pins, or bushings, with adjustable cushioning to reduce impact at stroke end.
Is the Airtac SC50 Standard Cylinder SC50X175N the Right Cylinder?
Choose the SC50 bore for mid-range clamping, pressing, and transfer tasks where the 982 N push at 0.5 MPa fits the load. If you need more force, step up to the SC63 which provides 1559 N at the same pressure; for a lighter, more compact solution, the SC40 delivers 628 N. All mounting accessories from the F-SC50 range fit this basic cylinder.
For a 175 mm stroke, the standard rod support is adequate for axial loads. If side loads are present, add an external linear guide or switch to a guided cylinder unit. When replacing an existing cylinder, match five points: 50 mm bore, 175 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet.
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 SC50X175N FAQ
At 0.7 MPa, the theoretical push force is 1374 N. The maximum push force at the 0.9 MPa operating limit is 1767 N. Always apply a safety factor for real-world dynamic loads.
Yes, if your current cylinder is a 50mm bore, 175mm stroke, double-acting tie-rod type with PT1/4 ports, basic mounting, and no magnet. The SC series is shorter than ISO 15552 cylinders, so check the 150 mm body length and rod dimensions before ordering.
