About the Airtac SC50 Standard Cylinder SC50X375N
The SC50X375N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 375 mm stroke, this model uses a 20 mm diameter piston rod with M16x1.5 male threads and features an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.
This unit is configured with NBR (nitrile) seals, making it a reliable choice for general industrial environments within the standard -20 to +70 °C temperature range. The body length A is 150 mm, giving a total extended length of approximately 525 mm. It has PT1/4 ports and does not include a built-in magnet or mounting accessories, supplied as a basic cylinder ready for direct integration or custom bracketry.

Where the Airtac SC50 Standard Cylinder SC50X375N Is Used
Material Stop & Diverter
Provides the 982 N push force needed to reliably actuate stops and diverters on medium-duty package handling lines, directing cartons without damaging them.
Clamping & Staking Fixtures
Delivers consistent clamping force for CNC machining fixtures or assembly staking operations, holding parts securely during processing with the 20 mm rod.
Agricultural Gate & Chute Control
Operates sorting gates or flow-control chutes on seed and grain handling equipment, with NBR seals providing good resistance to oils and greases in these environments.
Is the Airtac SC50 Standard Cylinder SC50X375N the Right Cylinder?
Select the SC50X375N when your application requires a mid-range force of about 982 N at standard plant pressure. For a step up in force, the SC63 bore offers 1559 N at the same 0.5 MPa; for a lighter, more compact solution, the SC40 bore provides 628 N. The 375 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
This cylinder's 20 mm rod is robust, but at a 375 mm stroke, avoid direct, unsupported side loads which can cause rod bending and premature bearing wear. For applications with lateral forces, use an external linear guide or switch to a guided cylinder. For a direct replacement, match these five points: 50 mm bore, 375 mm stroke, PT port thread, basic mounting, and no 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 SC50X375N 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No, the AirTAC SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with the same bore, stroke, PT port, and basic mounting configuration.
