About the Airtac SC50 Standard Cylinder SC50X210TC
The AirTAC SC50X210TC is a double-acting pneumatic cylinder with a 50 mm bore and 210 mm stroke, factory-equipped with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 982 N of push force and 825 N on the pull stroke, rising to 1767 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 port connections. The integral air cushion is adjustable over a 21 mm length to decelerate the piston smoothly. The TC mount ships complete with the TCM1 trunnion bracket (order code F-SC50TC), allowing the cylinder body to pivot as the rod extends and retracts.

Where the Airtac SC50 Standard Cylinder SC50X210TC Is Used
Conveyor Diverter Gates
The centre trunnion mount lets the SC50X210TC pivot freely, making it ideal for actuating diverter flaps and sorting gates on package handling conveyors.
Welding Fixture Clamping
With 1767 N of clamping force available at 0.9 MPa, this cylinder securely holds steel fabrications in position during MIG or TIG welding operations.
Pivoting Linkage Actuation
The TC mount absorbs the arc motion of a pivoting linkage, reducing rod side-loading when driving levers, crank arms, or oscillating machine guards.
Is the Airtac SC50 Standard Cylinder SC50X210TC the Right Cylinder?
Choose the SC50 bore for mid-range clamping, pressing, and material handling where the 982 N push at 0.5 MPa is sufficient. If you need a higher force in the same stroke length, stepping up to the 63 mm bore delivers 1559 N at 0.5 MPa; for a lighter, more compact solution the 40 mm bore provides 628 N. The 210 mm stroke is within the 1200 mm maximum standard stroke for this bore.
This cylinder is a direct replacement for another AirTAC SC50 of identical bore, stroke, PT port thread, and TC centre trunnion mounting. For position sensing, select the -S magnet option to use CMSG/DMSG sensors. At this stroke length, avoid side loads on the unsupported rod; use an external linear guide or a guided cylinder if the load is not perfectly axial.
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 SC50X210TC FAQ
At 0.5 MPa the push force is 982 N and the pull force is 825 N. At 0.7 MPa push rises 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.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions and accessory brackets are not interchangeable. It directly replaces another AirTAC SC50 cylinder with matching bore, stroke, PT ports, and TC centre trunnion mount.
