About the Airtac SC50 Standard Cylinder SC50X850S
The AirTAC SC50X850S is a double-acting tie-rod cylinder with a 50 mm bore and an 850 mm stroke, pre-fitted with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. Operating on filtered air at 0.15–1.0 MPa, it generates a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-bore actuator for moderate transfer and clamping tasks.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 port connections. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, and the TPU/NBR seals support an operating temperature range of -20 to +70 °C. The total body length A is 150 mm, giving an extended length of approximately 1000 mm for this stroke.

Where the Airtac SC50 Standard Cylinder SC50X850S Is Used
Part Transfer with End-of-Stroke Sensing
The 850 mm stroke moves components between conveyor lines or workstations, while the built-in magnet allows CMSG sensors to confirm full extension and retraction for sequencing logic.
Automated Clamping & Fixturing
Delivers up to 1767 N of clamping force at 0.9 MPa. The sensor-ready barrel enables integration into automated CNC or welding fixtures that require position verification before cycle start.
Sorting Gate or Diverter Actuation
Operates a long-throw diverter gate in material handling systems. The adjustable cushion absorbs impact energy at the stroke ends, protecting the gate structure from shock loads.
Is the Airtac SC50 Standard Cylinder SC50X850S the Right Cylinder?
Choose the SC50X850S when your application needs a 50 mm bore with sensor feedback capability. If your force requirement is lower, stepping down to the 40 mm bore (628 N push at 0.5 MPa) can save space and air consumption; for higher force demands, the 63 mm bore provides 1559 N at the same pressure. At an 850 mm stroke, the rod is significantly extended—ensure side loads are minimal or use an external guide rail, as long unsupported strokes on a 20 mm rod are susceptible to bending under lateral force.
For a direct replacement, match five key points: bore (50 mm), stroke (850 mm), PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This cylinder is a genuine AirTAC SC tie-rod unit, dimensionally shorter than an ISO 15552 profile cylinder, so it is not a direct swap for ISO 15552 types.
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 SC50X850S FAQ
At 0.5 MPa (approx. 73 psi), the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa, push force increases to 1374 N, and at the maximum operating pressure of 0.9 MPa, it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, so you can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position. This model does not include the sensors themselves; order them separately.
