The AirTAC SC50 Standard Cylinder SC50X845S is a genuine double-acting standard air cylinder with a Ø50mm bore and 845mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X845S is a double-acting single-rod pneumatic cylinder delivering 982 N of push force and 825 N of pull force at 0.5 MPa. With an 845 mm stroke and a 20 mm diameter piston rod, it suits mid-range linear actuation tasks where sensor feedback is required—the built-in magnet (suffix -S) allows CMSG or DMSG reed switches to clamp directly onto the tie-rod barrel for precise end-of-stroke detection.
This 50 mm bore model uses PT1/4 ports and an M16x1.5 rod thread, with an adjustable air cushion length of 21 mm to decelerate the piston quietly. The body length A is 150 mm, giving a total extended length of approximately 995 mm. Operating pressure spans 0.15–1.0 MPa, with a proof pressure of 1.5 MPa, and the standard TPU seals work reliably from -20 to +70 °C.

The 845 mm stroke moves components between distant conveyor stations or work cells. The built-in magnet enables end-of-stroke confirmation to sequence downstream automation reliably.
Actuates diverter gates or flippers on packaging lines. The 982 N push force at 0.5 MPa handles medium-weight product flow, while CMSG sensors verify gate position for error-proofing.
Pushes pallets or slip sheets out of a magazine with consistent force. The tie-rod construction withstands the repetitive impact of high-cycle dispensing operations.
Choose the SC50 bore when your application needs roughly 980–1370 N of force at typical shop air pressures (0.5–0.7 MPa). If you require more force, step up to the SC63 bore, which provides 1559 N push at 0.5 MPa; for a lighter, more compact solution, the SC40 bore offers 628 N. At 845 mm stroke, the unsupported rod length is significant—evaluate side loads carefully and consider an external linear guide or a guided cylinder if the load is not purely axial, as long strokes amplify rod-bearing bending moments.
For a direct replacement, match five key attributes: 50 mm bore, 845 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor mounting, and the basic (no bracket) mounting configuration. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder produces 982 N pushing and 825 N pulling. At 0.7 MPa these rise to 1374 N push and 1155 N pull. The maximum theoretical force at 1.0 MPa is 200 kgf (1960 N). Always apply a safety factor for real-world loads.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions and tie-rod spacing differ. It directly replaces another AirTAC SC50 cylinder with matching stroke, port thread, magnet option, and mounting style.
