About the Airtac SC50 Standard Cylinder SC50X210STC
The AirTAC SC50X210STC is a double-acting tie-rod cylinder with a 50 mm bore and 210 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion (TC) mount with the TCM1 bracket (F-SC50TC) for pivoting applications. The standard TPU seals and PT1/4 port threads suit compressed air systems operating from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X210STC Is Used
Conveyor Diverter Gates
The 50 mm bore provides ample force to shift medium-weight packages on sortation conveyors, with the trunnion mount allowing the cylinder body to pivot as the gate swings.
Clamping & Fixturing
Delivers 1767 N at 0.9 MPa for secure workpiece clamping in CNC fixtures. The built-in magnet enables end-of-stroke confirmation via reed sensors.
Agricultural Gate Actuation
Operates chute gates and diverters on seed or grain handling equipment. The TPU seals handle dusty environments, and the trunnion mount absorbs misalignment.
Is the Airtac SC50 Standard Cylinder SC50X210STC the Right Cylinder?
Choose the SC50 bore when your application needs roughly 980 N at 0.5 MPa; if you require around 630 N, step down to the SC40, or move up to the SC63 for about 1560 N. The 210 mm stroke is within the 1200 mm maximum standard stroke for bore 50.
For this stroke length, ensure the load is guided if any side force is present—an unsupported 20 mm rod at 210 mm extension can bend under lateral load. When replacing, match bore (50 mm), stroke (210 mm), PT1/4 ports, centre trunnion mount (F-SC50TC), and the magnet option (-S) to retain sensor functionality.
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 SC50X210STC FAQ
At 0.5 MPa the theoretical push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length (A=150 mm) than an ISO 15552 profile cylinder, so mounting dimensions and end-cap patterns differ. It directly replaces another AirTAC SC50 of the same stroke, port thread, and trunnion mount.
