About the Airtac SC50 Standard Cylinder SC50X370
The SC50X370 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 370 mm stroke, this model is well-suited for medium-duty linear actuation tasks where a balance of force and compact length is required.
This cylinder features a 20 mm diameter piston rod with an M16x1.5 thread and PT1/4 ports. The total body length is 150 mm, resulting in an extended length of approximately 520 mm. An adjustable air cushion decelerates the piston over the final 21 mm of travel to reduce end-of-stroke impact, protecting the end caps and the load.

Where the Airtac SC50 Standard Cylinder SC50X370 Is Used
Material Stops and Gates
The 982 N force at 0.5 MPa is ideal for actuating stop gates or diverter arms on light to medium-duty conveyor lines, providing reliable part separation.
Clamping and Pressing
Used in assembly jigs for clamping workpieces during welding or gluing, where the 370 mm stroke provides ample reach and the adjustable cushion ensures a gentle contact.
Packaging Machinery
Suitable for case erectors or carton flap tucking mechanisms, delivering consistent push force to fold and seal packaging materials in automated lines.
Is the Airtac SC50 Standard Cylinder SC50X370 the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at the same 0.5 MPa pressure. If a shorter overall length is acceptable and less force is needed, the 40 mm bore SC40 series offers 628 N. At a 370 mm stroke, the 20 mm rod is robust, but any significant side loading should be managed with an external linear guide to prevent rod bearing wear and bending.
When replacing an existing cylinder, ensure a direct match across five key points: bore (50 mm), stroke (370 mm), port thread (PT1/4), mounting style (basic, no bracket), and the presence of a magnet (this model has none). 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 SC50X370 FAQ
The theoretical push force is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and 1767 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is 825 N at 0.5 MPa due to the area of the 20 mm rod.
No. The SC50X370 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the end of stroke. For load holding, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
