About the Airtac SC50 Standard Cylinder SC50X395S
The AirTAC SC50X395S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a 395 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at the maximum operating pressure of 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for end-of-stroke detection.
This model uses a PT1/4 port and an M16x1.5 rod thread, with a body length A of 150 mm. The tie-rod construction makes it shorter than an equivalent ISO 15552 cylinder, so it is not a dimensional direct for those profiles. The TPU seals offer a standard operating range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X395S Is Used
Material Sorting Gates
The 395 mm stroke and magnetic sensing make this cylinder ideal for actuating diverter gates on conveyor lines, confirming open/closed position with CMSG sensors.
Clamping & Staking Fixtures
Delivers a controlled 982 N clamping force at 0.5 MPa, suitable for holding parts during light assembly or staking operations where sensor confirmation is required.
Product Pushers & Ejectors
The long 395 mm reach pushes cartons or products off a line. The adjustable cushion absorbs impact energy at the end of the stroke, protecting the actuator.
Is the Airtac SC50 Standard Cylinder SC50X395S the Right Cylinder?
Choose the SC50X395S when you need approximately 982 N of force at standard plant pressure and require magnetic piston sensing. If your load demands more force, the next step up is the 63 mm bore (SC63 series), which provides 1559 N at 0.5 MPa. For lower force requirements, the 40 mm bore delivers 628 N.
For this 395 mm stroke, ensure the rod is protected from side loads. Long, unsupported strokes on a 20 mm rod can experience bending moments; use an external linear guide or a guided cylinder if the load is not perfectly axial. When replacing this unit, match five points: 50 mm bore, 395 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style.
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 SC50X395S FAQ
At 0.7 MPa (7 bar), the theoretical push force is 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, due to the area reduction from the 20 mm piston rod.
Yes. The -S suffix in the model code SC50X395S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position.
