About the Airtac SC50 Standard Cylinder SC50X500STC
The SC50X500STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. Its 50 mm bore and 500 mm stroke suit medium-force linear tasks where a pivoting mount is needed, with a 20 mm diameter piston rod providing solid column strength.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion mount (TC suffix) supplied with the TCM1 bracket for swinging-load applications. The body length A is 150 mm, giving an extended length of approximately 650 mm. Adjustable air cushioning at both ends decelerates the piston smoothly over a 21 mm cushion length.

Where the Airtac SC50 Standard Cylinder SC50X500STC Is Used
Conveyor Diverter Gates
The centre trunnion mount allows the cylinder body to pivot as it actuates a diverter gate on a packaging or sorting conveyor, handling medium product weights with the 982 N push force at standard plant air pressure.
Welding Fixture Clamping
With a built-in magnet for end-of-stroke confirmation via CMSG sensors, this cylinder confirms clamp closure on automotive welding jigs. The 500 mm stroke accommodates deep fixtures, and the trunnion mount absorbs fixture misalignment.
Hopper or Chute Actuation
Operates a discharge chute or hopper door on agricultural processing equipment. The pivoting TC mount follows the door's arc, while the TPU seals handle dusty, ambient-temperature environments from -20 to +70 °C.
Is the Airtac SC50 Standard Cylinder SC50X500STC the Right Cylinder?
Choose the SC50 bore when your application needs around 982 N at 0.5 MPa. If you require more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 bore provides 628 N. This 500 mm stroke is within the 1200 mm maximum standard stroke for bore 50.
For a 500 mm stroke, side loads must be managed carefully—the 20 mm rod can experience bending stress if the load is not guided externally. Use an external guide rail or rod-alignment coupler, especially at higher speeds. When replacing an existing cylinder, match five points: 50 mm bore, 500 mm stroke, PT port thread, centre trunnion (TC) mount with F-SC50TC bracket, and the built-in magnet for sensor compatibility.
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 SC50X500STC FAQ
At 0.7 MPa operating pressure, the SC50 bore produces 1374 N of push force on the outstroke and 825 N of pull force on the retract stroke. The maximum operating force at 0.9 MPa is 1767 N push.
Yes. The -S suffix in the model code means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rod slots to detect piston position without any additional brackets.
