The AirTAC SC50 Standard Cylinder SC50X650TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 650mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X650TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), built around a 20 mm diameter piston rod. Its 650 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making this a standard-configuration actuator with a body length A of 150 mm.
This model is factory-configured with a TC centre trunnion mount (supplied with the TCM1 bracket, order code F-SC50TC), allowing the cylinder to pivot during operation for swinging or articulating loads. The adjustable air cushion at each end decelerates the piston across a 21 mm cushion zone, reducing end-of-stroke impact without locking the rod position.

The 650 mm stroke and centre trunnion pivot suit conveyor diverter gates, where the cylinder swings to redirect packages or pallets between lanes.
Delivers 982 N at 0.5 MPa for robust workpiece clamping in machining centres or welding jigs, with the trunnion mount absorbing alignment shifts.
Operates chute doors or flow gates on seed drills and harvesters, pivoting smoothly on the TC mount as the mechanism cycles through its arc.
For a step up in force, the 63 mm bore SC63 series offers 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore provides 628 N. At 650 mm stroke, ensure the rod is not subjected to direct side loading—long unsupported rods can bend under lateral force. Use an external linear guide or a guided cylinder if side loads are present.
When replacing this cylinder, match five key points: 50 mm bore, 650 mm stroke, PT1/4 port thread, TC centre trunnion mounting with TCM1 bracket, and the standard TPU seal. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, it produces 982 N extending and 825 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force is 1767 N.
Yes, the TC suffix means the cylinder comes with the TCM1 trunnion mounting bracket pre-assembled. The accessory part code for the complete set is F-SC50TC.
