About the Airtac SC50 Standard Cylinder SC50X1200SLB
The SC50X1200SLB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built for long linear strokes up to 1200 mm. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, while the built-in magnet enables direct mounting of CMSG/DMSG/EMSG sensors for precise position feedback.
This model features an LB foot mount (accessory F-SC50LB) for stable surface installation and operates on filtered air from 0.15 to 1.0 MPa. With a body length of 150 mm, the total extended length reaches 1350 mm, making it a genuine AirTAC solution for applications needing extended reach with reliable sensor integration.

Where the Airtac SC50 Standard Cylinder SC50X1200SLB Is Used
Long-Reach Material Transfer
The 1200 mm stroke and 982 N push force efficiently transfer parts between distant conveyor lines, with the built-in magnet allowing end-of-stroke confirmation via CMSG sensors.
Automated Gluing or Dispensing
Delivers consistent, extended linear motion for adhesive bead application across large panels, where the LB foot mount ensures rigid, vibration-resistant alignment.
Palletizing Pusher Arm
Pushes boxes or trays onto a pallet with 1374 N of force at 0.7 MPa. The adjustable cushion softens the impact at the end of the long stroke, protecting the load and cylinder.
Is the Airtac SC50 Standard Cylinder SC50X1200SLB the Right Cylinder?
Choose the SC50 bore when your application requires around 982 N of force at standard plant pressure. For higher force, step up to the SC63 bore which provides 1559 N at 0.5 MPa; for a lighter, more compact design, the SC40 bore offers 628 N. At a 1200 mm stroke, side-load management is critical—never subject the unsupported rod to lateral forces, and consider an external guide rail or a guided cylinder if the load is not perfectly axial.
For a direct replacement, match these five points: 50 mm bore, 1200 mm stroke, PT port thread, LB foot mounting, and the -S magnet for sensor compatibility. This cylinder is a tie-rod design and will only interchange with another AirTAC SC50 of identical 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 SC50X1200SLB FAQ
At 0.7 MPa operating pressure, the theoretical push force is 1374 Newtons. The pull force on the retract stroke is 825 N at the same pressure, due to the area reduction from the 20 mm piston rod.
No. The SC50 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the valve is centered, the piston will drift. You must add a pilot-operated check valve or an external rod lock for any load-holding application.
