About the Airtac SC50 Standard Cylinder SC50X100N
The SC50X100N is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, rising to 1767 N at 0.9 MPa. With a 50 mm bore and 100 mm stroke, this tie-rod actuator uses a 20 mm diameter piston rod with M16x1.5 male threads, providing robust linear motion for medium-duty tasks.
The N suffix specifies NBR (nitrile) seals, offering good resistance to oils and greases in standard industrial air. Its compact body length A of 150 mm plus the 100 mm stroke gives a total extended length of approximately 250 mm, fitting neatly into machinery where space is a consideration.

Where the Airtac SC50 Standard Cylinder SC50X100N Is Used
Part Diverter Gates
Actuates gates on conveyor lines to sort packages by weight or barcode, using the 100 mm stroke for a clean, repeatable push at 0.5-0.7 MPa line pressure.
Clamping Fixtures
Provides 1374 N of clamping force at 0.7 MPa for holding metal or plastic parts during drilling, milling, or welding operations in CNC work cells.
Hopper Door Actuation
Opens and closes discharge doors on agricultural hoppers or silos, with NBR seals handling dusty, oily environments typical in feed and grain processing.
Is the Airtac SC50 Standard Cylinder SC50X100N the Right Cylinder?
Select the SC50X100N when your application needs around 980 N of force at standard plant pressure. If your load is lighter, stepping down to a 40 mm bore reduces push force to 628 N at 0.5 MPa, saving air consumption. For heavier demands, the 63 mm bore provides 1559 N at the same pressure. Always match the replacement cylinder on five key points: 50 mm bore, 100 mm stroke, PT1/4 port thread, NBR seal material, and basic (no bracket) mounting. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X100N 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.
No, the SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Only replace another AirTAC SC50 or an equivalent tie-rod cylinder with matching bore, stroke, PT1/4 ports, and NBR seals.
