About the Airtac SC50 Standard Cylinder SC50X400TC
The SC50X400TC is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force at 0.5 MPa, rising to 1767 N push at 0.9 MPa. Its 50 mm bore and 400 mm stroke suit medium-force linear tasks, with a 20 mm diameter piston rod and PT1/4 port threads.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during operation. The adjustable air cushion at each end decelerates the piston smoothly, and the standard TPU seals provide reliable service from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X400TC Is Used
Conveyor Diverter Gates
The 400 mm stroke and trunnion mount allow the cylinder to pivot a diverter gate on packaging lines, handling medium product weights with smooth cushioning at stroke ends.
Clamping & Fixturing
Delivers 1767 N of clamping force at 0.9 MPa for machining fixtures. The centre trunnion lets the cylinder body swing, simplifying mounting in tight jig layouts.
Agricultural Implement Control
Controls chutes or hopper doors on farm equipment. The TPU seals and PT ports handle typical workshop air, and the pivoting TC mount follows the arc of the door linkage.
Is the Airtac SC50 Standard Cylinder SC50X400TC the Right Cylinder?
For higher force, step up to the 63 mm bore SC63 series, which provides 1559 N push at 0.5 MPa. For lighter, faster applications, the 40 mm bore SC40 series offers 628 N. At 400 mm stroke, ensure the rod is guided externally if side loads are present, as the 20 mm rod can experience bending moments under off-axis forces.
To replace an existing cylinder, match five points: 50 mm bore, 400 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and confirm no built-in magnet is required. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X400TC FAQ
At 0.7 MPa operating pressure, the SC50X400TC generates 1374 N of push force and 1155 N of pull force. The maximum operating force at 0.9 MPa is 1767 N push.
Yes, the TC suffix means the cylinder is supplied with the TCM1 trunnion mounting bracket (order code F-SC50TC). The bracket allows the cylinder to pivot around its centre of gravity, which is essential for swinging or articulating loads.
