The AirTAC SC50 Standard Cylinder SC50X70SN is a genuine double-acting standard air cylinder with a Ø50mm bore and 70mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X70SN is a double-acting tie-rod cylinder with a 50 mm bore and 70 mm stroke, fitted with NBR (nitrile) seals. At 0.5 MPa it generates 982 N of push force, making it a capable mid-range actuator for clamping, pressing, and transfer tasks.
This model uses a 20 mm piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston quietly at end-of-stroke, while the NBR seal material suits standard industrial environments operating between -20 and +70 °C.

Moves components between conveyor lanes or indexing stations with a 70 mm linear stroke and 982 N of push force at standard line pressure.
Applies controlled 982 N insertion force for bearing or bushing press-fit operations in automated assembly cells.
Secures workpieces in CNC or welding fixtures, using the 20 mm rod and NBR seals for reliable, repeatable clamping cycles.
Choose the SC50 bore when your application needs roughly 980 N at 0.5 MPa. If you need more force, stepping up to the SC63 delivers 1559 N at the same pressure; if you need less, the SC40 provides 628 N. For the 70 mm stroke, confirm the total extended length of approximately 220 mm (body length A 150 mm + stroke) fits your envelope.
When replacing an existing cylinder, match five points: 50 mm bore, 70 mm stroke, PT port thread, basic (no bracket) mounting, and no magnet. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC50 tie-rod units.
Quick checklist
At 0.7 MPa (7 bar) the SC50 bore produces 1374 N of push force and 825 N of pull force on the retract stroke, based on the official AirTAC thrust table for a 50 mm bore with a 20 mm rod.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It will only drop in as a direct replacement for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT ports, and basic mounting.
