About the Airtac SC80 Standard Cylinder SC80X50SN
The SC80X50SN is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa), making it a strong performer for short-stroke clamping and pressing tasks. Its 80 mm bore houses a 25 mm diameter piston rod with an M20x1.5 male thread, and the 50 mm stroke keeps the overall extended length compact at approximately 232 mm.
This model uses NBR (nitrile) seals, suitable for standard temperature ranges, and comes with PT1/4 port threads. The adjustable air cushion at each end (28 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact without locking the load.

Where the Airtac SC80 Standard Cylinder SC80X50SN Is Used
Short-Stroke Clamping
Delivers 2513 N at 0.5 MPa for secure workpiece clamping in machining fixtures and assembly jigs where space is limited.
Ejection & Stamping
Provides a quick, powerful 50 mm punch stroke for ejecting parts from moulds or light stamping operations on automated lines.
Diverter Gates
Actuates diverter gates on conveyor systems with a fast, repeatable 50 mm throw, handling product sorting reliably.
Is the Airtac SC80 Standard Cylinder SC80X50SN the Right Cylinder?
For applications needing slightly less force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If higher force is required, stepping up to the 100 mm bore yields 3927 N at the same pressure. Always match replacement cylinders on all five key points: bore (80 mm), stroke (50 mm), port thread (PT), mounting style (basic), and magnet option (none).
At this short 50 mm stroke, side-load bending on the 25 mm rod is minimal, but for any off-axis force, an external guide or rod-alignment coupler is still recommended to protect the rod bearing and piston seals.
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 SC80 Standard Cylinder SC80X50SN FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N.
No. The SC80X50SN is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. For load-holding, you must add a pilot-operated check valve or an external mechanical brake.
