About the Airtac SC50 Standard Cylinder SC50X450LB
The SC50X450LB 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. With a 50 mm bore and 450 mm stroke, it is built for linear applications needing a moderate force envelope and a mid-range travel distance.
This model comes fitted with an LB foot mount (F-SC50LB) for secure surface mounting. The 20 mm diameter piston rod and PT1/4 ports ensure reliable air flow, 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 600 mm.

Where the Airtac SC50 Standard Cylinder SC50X450LB Is Used
Material Transfer
Pushes or diverts packages on a conveyor line where a 450 mm stroke is needed to move items between belts or into a sorting lane.
Clamping & Fixturing
Applies consistent clamping force up to 1767 N for holding workpieces in CNC machining or welding jigs, with the LB mount ensuring a rigid, fixed position.
Bin Tipping
Actuates a bin or hopper tipping mechanism, using the 450 mm stroke to achieve the necessary dump angle for small parts or waste material.
Is the Airtac SC50 Standard Cylinder SC50X450LB the Right Cylinder?
Choose the SC50 bore when your application requires between 982 N and 1767 N of force. If you need more force, step up to the SC63 which provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 offers 628 N. For this 450 mm stroke, ensure the rod is protected from side loads—consider an external guide or a guided cylinder if the load is not perfectly axial, as a long, unsupported 20 mm rod can be damaged by bending moments.
To replace an existing cylinder, match five key points: bore (50 mm), stroke (450 mm), port thread (PT1/4), mounting accessory (LB foot mount), and magnet option (none on this model). This ensures a direct fit for another AirTAC SC tie-rod cylinder.
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 SC50X450LB 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 0.9 MPa, the push force increases to 1767 N.
This specific model, SC50X450LB, is configured with a fixed LB foot mount for surface mounting and is not designed to pivot. For a pivoting application, you would need a model with a TC centre trunnion or a CA/CB rear clevis mount.
