About the Airtac SC50 Standard Cylinder SC50X435S
The SC50X435S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a 435 mm stroke, this model includes a built-in magnet (-S suffix) that allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for non-contact position sensing.
Its 150 mm body length (dimension A) plus the 435 mm stroke gives an extended length of approximately 585 mm. The adjustable pneumatic cushion (21 mm cushion length) decelerates the piston at end-of-travel to reduce impact, while the PT1/4 port and M16x1.5 rod thread provide standard connectivity. This genuine AirTAC cylinder operates on 40 µm filtered air from -20 to +70 °C with its default TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X435S Is Used
Material Handling Pusher
The 435 mm stroke and 50 mm bore provide ample reach and force to push cartons or totes off a conveyor line. The built-in magnet enables end-of-stroke confirmation with a CMSG sensor.
Automated Clamping Fixture
Delivers consistent 982 N clamping force at 0.5 MPa for holding workpieces during machining or assembly. Sensor feedback confirms the clamp is fully engaged before the cycle starts.
Bin Diverter Gate
Operates a diverter gate on a gravity chute or sorting system. The long 435 mm stroke moves the gate through its full arc, while the magnet allows position verification at both ends.
Is the Airtac SC50 Standard Cylinder SC50X435S the Right Cylinder?
Choose the SC50 bore when your application needs roughly 980-1370 N of force at typical shop air pressures (0.5-0.7 MPa). If you require more force, step up to the SC63 which provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 delivers 628 N. At a 435 mm stroke, the unsupported rod length is significant—ensure the load is guided externally or consider a guided cylinder to prevent rod bending and premature bearing wear under side loads. For a direct replacement, match five attributes: 50 mm bore, 435 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no accessory) mounting configuration.
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 SC50X435S FAQ
At 0.5 MPa (approx. 73 psi), the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, the SC50X435S is dimensionally identical to a non-magnet SC50X435. The built-in magnet does not change the envelope or mounting dimensions, so it is a direct replacement. You can simply ignore the magnet if sensors are not needed, or add CMSG/DMSG sensors later for position monitoring.
