The AirTAC SC50 Standard Cylinder SC50X765S is a genuine double-acting standard air cylinder with a Ø50mm bore and 765mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X765S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a non-standard 765 mm stroke, delivering a push force of 982 N at 0.5 MPa. Its 20 mm diameter piston rod and PT1/4 port ensure a robust flow path, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This tie-rod cylinder features an adjustable air cushion (21 mm length) to decelerate the piston smoothly, reducing end-cap impact. With a body length A of 150 mm, the total extended length reaches approximately 915 mm. For strokes of this length, side loading must be carefully managed to prevent rod bearing wear and bending.

The 765 mm stroke moves components between distant conveyor stations, with the magnetic piston enabling sensor confirmation at both ends of travel.
Applies consistent 982 N clamping force at 0.5 MPa to hold workpieces during adhesive curing, with position feedback from barrel-mounted sensors.
Operates a tall lift gate or diverter panel in material handling systems, using the adjustable cushion to soften the stop at the top and bottom of the stroke.
Select the SC50 bore where the 982 N push force at 0.5 MPa meets the load requirement; if higher force is needed, step up to the SC63 bore providing 1559 N at the same pressure. For this 765 mm stroke, an external guide or guided cylinder is strongly recommended to protect the 20 mm rod from bending under side loads.
To ensure a correct replacement, match five points: 50 mm bore, 765 mm stroke, PT port thread, the built-in magnet (-S suffix for sensor compatibility), and the basic mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 982 N. At 0.7 MPa it increases to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N.
Yes, for a stroke of 765 mm with a 20 mm rod, an external guide or a guided cylinder is strongly recommended. Side loads can cause the rod to bend or prematurely wear the bearing and seals, especially when the rod is fully extended.
