The AirTAC SC50 Standard Cylinder SC50X80TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X80TC is a 50 mm bore, 80 mm stroke double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). The 20 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration at end-of-stroke, while the PT1/4 port supplies ample flow for speeds up to 800 mm/s.
This model is factory-configured with the TC centre trunnion mounting (supplied with TCM1 bracket, part code F-SC50TC). The trunnion allows the cylinder body to pivot, making it ideal for swinging or articulating loads. Operating on filtered air from 0.15 to 1.0 MPa, the TPU/NBR seals cover a standard temperature range of -20 to +70 °C.

The 982 N push force at 0.5 MPa easily actuates diverter flaps and sorting gates on packaging lines, while the centre trunnion mount absorbs the pivoting motion without side-loading the rod.
Provides consistent, controlled clamping force for CNC fixtures and welding jigs. The 80 mm stroke offers enough travel to clear parts during load/unload cycles.
Operates discharge gates on agricultural hoppers and chutes. The trunnion mount handles the arc of the gate linkage, and the TPU seals withstand dusty, ambient-temperature environments.
For applications needing more force, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa; for lighter, faster moves the 40 mm bore delivers 628 N. The 80 mm stroke is a standard length within the 50 mm bore's 1200 mm maximum, so lead times remain short.
When replacing an existing cylinder, match five points to ensure direct fit: 50 mm bore, 80 mm stroke, PT1/4 port thread, TC centre trunnion mounting (with F-SC50TC bracket), and confirm whether a magnet sensor option is required (this model is non-magnetic).
Quick checklist
At 0.7 MPa (7 bar) supply pressure, the theoretical push force is 1374 N and the pull force (rod side) is 825 N. For maximum operating pressure of 0.9 MPa, push force reaches 1767 N. Always apply a safety factor for real-world dynamic loads.
Yes, provided the original is a 50 mm bore, 80 mm stroke tie-rod cylinder with PT1/4 ports and a centre trunnion mount. The SC series is shorter than ISO 15552 cylinders, so verify the trunnion-to-rod-end centre distance. The mounting kit F-SC50TC is included with this model.
