About the Airtac SC50 Standard Cylinder SC50X40TC
The SC50X40TC is a double-acting pneumatic cylinder with a 50 mm bore and a short 40 mm stroke, delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration in compact linear transfer tasks.
This model is factory-configured with a TC centre trunnion mount, supplied together with the TCM1 bracket (F-SC50TC), allowing the cylinder body to pivot during operation. The standard PT1/4 ports and TPU seals suit filtered-air systems operating from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X40TC Is Used
Part Shifting
Short 40 mm stroke and centre trunnion pivot suit rapid lateral part-shifting mechanisms on packaging lines.
Clamping Fixtures
Delivers 1767 N of clamping force at 0.9 MPa for holding workpieces during machining or welding.
Diverter Gates
Pivoting TC mount allows the cylinder to swing, ideal for actuating diverter gates on conveyor systems.
Is the Airtac SC50 Standard Cylinder SC50X40TC the Right Cylinder?
For a 50 mm bore, the SC50X40TC provides a balanced force class between the smaller 40 mm bore (628 N at 0.5 MPa) and the larger 63 mm bore (1559 N). The 40 mm stroke is well within the 1200 mm maximum standard stroke for this bore. When replacing an existing unit, match five points: 50 mm bore, 40 mm stroke, PT1/4 port thread, TC centre trunnion mounting, and the absence of a magnet.
Although this is a short-stroke application, always guide the load externally if any side force is present; the tie-rod construction and rod bearing are designed for axial loads.
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 SC50X40TC FAQ
At 0.5 MPa the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
No. The SC50X40TC is a double-acting cylinder and will drift or drop if pressure is exhausted. For load holding without live pressure, an external rod lock or pilot-operated check valve is required.
