The AirTAC Airtac SC50 Standard Cylinder SC50X980S is a genuine double-acting standard air cylinder with a Ø50mm bore and 980mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X980S is a double-acting pneumatic cylinder with a 50 mm bore and a long 980 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa. Its 20 mm diameter piston rod and PT1/4 ports provide a robust fluid path for consistent actuation in automation tasks requiring extended linear reach.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for precise, non-contact position feedback. The adjustable air cushion at each end decelerates the piston smoothly, protecting the end caps during high-cycle operation.

Moves components across wide conveyor gaps or between distant process stations, using the full 980 mm stroke and sensor-confirmed end positions.
Operates tall diverter gates or flippers in logistics systems, where the extended stroke directs packages onto separate lanes with magnet-sensed open/closed states.
Powers long-travel clamping arms on welding or assembly jigs, retracting fully for clear part loading and extending with 982 N to secure workpieces.
For applications requiring a longer stroke with moderate force, the SC50 bore provides 982 N at 0.5 MPa. If your load demands higher force, stepping up to the SC63 bore offers 1559 N at the same pressure. For a shorter, more compact design, the SC40 bore delivers 628 N.
This 980 mm stroke approaches the maximum standard limit for the 50 mm bore. To prevent rod bending or uneven bearing wear under side loads at this extension, an external linear guide or a guided cylinder assembly is strongly recommended. For direct replacement, match the 50 mm bore, 980 mm stroke, PT1/4 port thread, basic mounting, and ensure the replacement has a built-in magnet for sensor compatibility.
Quick checklist
At 0.7 MPa operating pressure, the 50 mm bore generates a theoretical push force of 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, due to the area reduction from the 20 mm piston rod.
Yes. The -S suffix in SC50X980S designates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped onto the cylinder body for reliable end-of-stroke or mid-stroke position sensing without external brackets.
