About the Airtac SC50 Standard Cylinder SC50X245S
The SC50X245S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a robust mid-range actuator for industrial automation. Its 50 mm bore houses a 20 mm diameter piston rod with M16x1.5 male threads, and the 245 mm stroke sits well within the 1200 mm maximum standard stroke for this bore size.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. This allows easy, tool-free mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position sensing. The adjustable air cushion at each end decelerates the piston smoothly, with a cushion length of 21 mm, protecting the end caps during high-speed cycles.

Where the Airtac SC50 Standard Cylinder SC50X245S Is Used
Package Sorting Gates
The 245 mm stroke and 50 mm bore provide the reach and force to divert medium-weight parcels on conveyor lines. The built-in magnet enables sensor feedback to confirm gate position for reliable sortation control.
Clamping & Staking Fixtures
Delivers a consistent 982 N clamping force at 0.5 MPa for holding parts during welding or assembly. The -S magnet allows sensors to verify the clamp is fully engaged before the cycle starts.
Vertical Lift-Assist Mechanisms
With a pull force of 825 N at 0.5 MPa, this cylinder can assist in raising and lowering moderate loads on lift tables or ergonomic workstations, using the magnet for intermediate position stops.
Is the Airtac SC50 Standard Cylinder SC50X245S the Right Cylinder?
Choose the SC50 bore when your application requires between 982 N and 1767 N of force at standard plant air pressures. If your load demands more force, stepping up to the SC63 bore provides 1559 N at 0.5 MPa. For a lighter, more compact solution, the SC40 bore offers 628 N. Always ensure the 20 mm rod is adequately supported against side loads, particularly with a 245 mm stroke.
For a direct replacement, match these five key attributes: 50 mm bore, 245 mm stroke, PT1/4 port thread, the basic mounting configuration (no factory-fitted brackets), and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile, so it is not a drop-in replacement for that standard.
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 SC50X245S FAQ
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 2000 N (200 kgf).
Yes. The -S suffix in the model code SC50X245S designates a built-in magnet. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors on the cylinder barrel to detect piston position without additional brackets.
