About the Airtac SC50 Standard Cylinder SC50X175SN
The AirTAC SC50X175SN is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a solid mid-range actuator for general automation. Its 20 mm diameter rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for a 175 mm stroke.
This model includes a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the barrel for non-contact position sensing. The NBR seal (-N suffix) offers good oil resistance for lubricated air systems, while the standard PT port thread keeps installation straightforward.

Where the Airtac SC50 Standard Cylinder SC50X175SN Is Used
Material Handling
Pushes or diverts packages on conveyors with sensor feedback confirming each cycle, using the 982 N push force at standard plant pressure.
Clamping & Fixturing
Applies consistent clamping force in machining jigs, with NBR seals tolerating oily workshop air and the magnet signaling clamp engagement.
Agricultural Machinery
Actuates gates or chutes on farm equipment where NBR seals handle dust and oil mist, and the magnet confirms position remotely.
Is the Airtac SC50 Standard Cylinder SC50X175SN the Right Cylinder?
Choose the SC50 when you need more force than the 32 mm bore (402 N push) but a more compact body than the 63 mm (1559 N). For strokes of 175 mm, the standard tie-rod construction handles axial loads well; if side loads are present, add an external guide or linear bearing to protect the rod bearing. To match a replacement, verify five points: 50 mm bore, 175 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style.
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 SC50X175SN FAQ
At 0.7 MPa (7 bar) operating pressure, the push force is 1374 N. The pull force at the same pressure is 825 N due to the 20 mm rod reducing the piston area on the retract side.
Yes. The -S suffix in the model code means a magnet is built into the piston, so AirTAC CMSG, DMSG, or EMSG sensors clip onto the barrel for end-of-stroke detection.
