About the Airtac SC50 Standard Cylinder SC50X780SN
The SC50X780SN is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a capable mid-bore actuator for medium-load linear tasks. Its 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the 780 mm stroke suits extended reach applications.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke or mid-stroke position feedback without external brackets. The -N suffix specifies NBR (nitrile) seals, offering reliable performance within the standard -20 to +70 °C temperature range. The body length A is 150 mm, giving a total extended length of approximately 930 mm.

Where the Airtac SC50 Standard Cylinder SC50X780SN Is Used
Material Transfer
Extends across a wide conveyor gap to push or divert medium-weight cartons and totes, with sensor confirmation of full extension and retraction.
Assembly Pressing
Provides the controlled 1374 N force at 0.7 MPa for pressing bushings or bearings into housings on an automated assembly station.
Bin Diverter Gate
Actuates a long-throw diverter gate in a gravity chute, using the built-in magnet to verify gate position for sorting accuracy.
Is the Airtac SC50 Standard Cylinder SC50X780SN the Right Cylinder?
For applications requiring slightly less force, stepping down to a 40 mm bore provides 879 N at 0.7 MPa, while moving up to a 63 mm bore offers 2182 N at the same pressure. With a 780 mm stroke, this cylinder has a significant unsupported rod length; ensure the load is guided externally or consider a guided cylinder to prevent rod bending and premature bearing wear under side loads.
When replacing this cylinder, match five key points: 50 mm bore, 780 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the NBR seal material. This ensures identical mechanical and sensing performance.
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 SC50X780SN FAQ
At 0.7 MPa operating pressure, this 50 mm bore cylinder produces a theoretical push force of 1374 N and a pull force of approximately 825 N (accounting for the 20 mm rod area).
Yes. The -S suffix indicates a built-in magnet, allowing you to clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the cylinder barrel for non-contact position sensing.
