About the Airtac SC50 Standard Cylinder SC50X275N
The SC50X275N 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 operating pressure. With a 50 mm bore, 20 mm piston rod, and 275 mm stroke, it suits medium-force linear actuation tasks where NBR seals are preferred for their balanced performance.
This tie-rod cylinder features adjustable pneumatic cushioning over a 21 mm length to decelerate end-of-stroke impact. The body length A is 150 mm, making the total extended length approximately 425 mm. Ports are PT1/4 with an M16x1.5 rod thread, and the NBR seal material provides reliable sealing for standard industrial air supplies.

Where the Airtac SC50 Standard Cylinder SC50X275N Is Used
Part Transfer & Sorting
Provides the 982 N push force needed to divert medium-weight packages or components on conveyor lines, with the 275 mm stroke covering typical belt widths.
Clamping & Fixturing
Delivers consistent clamping force up to 1767 N at 0.9 MPa for CNC fixtures and welding jigs, holding workpieces securely during machining or assembly.
Agricultural Gate & Hopper Actuation
Operates chute gates and hopper doors on seed drills or feed systems, where the NBR seals offer good resistance to oils and greases commonly found in farm equipment.
Is the Airtac SC50 Standard Cylinder SC50X275N the Right Cylinder?
Choose the SC50 when your application needs roughly 1000 N of force at typical shop air. If you need more force, step up to the SC63 bore which provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 delivers 628 N. This 275 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
For strokes of this length, avoid placing side loads directly on the rod—the 20 mm rod can bend under lateral force. Use an external guide rail or a guided cylinder if the load is not perfectly axial. When replacing an existing cylinder, match the 50 mm bore, 275 mm stroke, PT1/4 ports, basic mounting, and ensure the seal material (NBR) is compatible with your system.
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 SC50X275N FAQ
At 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 reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes, if the bore (50 mm), stroke (275 mm), port thread (PT1/4), and mounting style match. This model has NBR seals, so confirm the seal material is compatible with your application's temperature and lubricant. It does not include a magnet or mounting accessories.
