About the Airtac SC50 Standard Cylinder SC50X300LB
The AirTAC SC50X300LB is a double-acting pneumatic cylinder with a 50 mm bore and 300 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa. Its 20 mm diameter piston rod and PT1/4 port provide a robust connection for industrial automation tasks.
This model is configured with an LB foot mounting (accessory F-SC50LB) for stable, axial surface installation. The standard TPU seals offer a reliable operating temperature range of -20 to +70 °C, making it a versatile workhorse for general manufacturing environments.

Where the Airtac SC50 Standard Cylinder SC50X300LB Is Used
Material Handling
Pushing boxes or totes off a conveyor line where a 300 mm stroke provides the necessary reach and the foot mount ensures a rigid, fixed position.
Clamping & Pressing
Applying a consistent clamping force in a woodworking jig or light assembly press, leveraging the 1767 N maximum force at 0.9 MPa.
Farm Equipment Actuation
Operating a gate or diverter chute on agricultural machinery, where the TPU seals handle dusty conditions and the foot mount simplifies installation.
Is the Airtac SC50 Standard Cylinder SC50X300LB the Right Cylinder?
For applications requiring higher force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N of push force at 0.5 MPa. With a 300 mm stroke, ensure that side loads on the 20 mm rod are managed; if the load is not guided externally, a guided cylinder or external linear rail is recommended to prevent rod bearing wear and bending. When replacing an existing cylinder, verify five key points: the 50 mm bore, 300 mm stroke, PT port thread, LB foot mounting, and the absence of a magnet.
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 SC50X300LB FAQ
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. The maximum push force at 0.9 MPa is 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a comparable ISO 15552 cylinder. It is not dimensionally interchangeable. Replacements must match another SC series cylinder with the same bore, stroke, port, and LB mounting.
