The AirTAC SC50 Standard Cylinder SC50X80 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 SC50X80 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with an 80 mm stroke. It generates a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a capable mid-range actuator for clamping and pressing tasks.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end of travel, and the total body length A is 150 mm, giving a compact footprint for its force class.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Applies 982 N at 0.5 MPa to seal cartons or press-fit caps, with adjustable cushioning to protect product surfaces at end of stroke.
Holds workpieces securely in CNC or welding jigs. The 20 mm rod resists bending under direct axial loads during machining.
Operates diverter gates on conveyors. The 80 mm stroke provides a clean shift between two lanes with fast 30-800 mm/s speed capability.
Choose the SC50X80 when 982 N of push force at 0.5 MPa meets your requirement. If you need more force, stepping up to the SC63 series provides 1559 N at the same pressure; for a lighter, more compact solution, the SC40 delivers 628 N. All mounting accessories (LB foot, FA/FB flanges, CA/CB clevises, TC centre trunnion) are ordered separately using the F-SC50 prefix.
For a direct replacement, match five points: 50 mm bore, 80 mm stroke, PT1/4 port thread, your existing mounting accessory, and whether a magnet is needed. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC is a tie-rod cylinder and is shorter in overall length than an ISO 15552 cylinder. It is a direct replacement only for another AirTAC SC50 cylinder with matching bore, stroke, port thread, and mounting.
