The AirTAC SC50 Standard Cylinder SC50X500SFB is a genuine double-acting standard air cylinder with a Ø50mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X500SFB is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 500 mm stroke, it features a 20 mm diameter piston rod with M16x1.5 male threads and an adjustable air cushion length of 21 mm to decelerate end-of-stroke impact.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and an FB rear rectangular flange (F-SC50FB) for secure cap-end panel mounting. The standard TPU seals provide reliable operation in ambient temperatures from -20 to +70 °C, with PT1/4 port threads for pneumatic connections.

The 500 mm stroke and 982 N push force at 0.5 MPa are ideal for stopping or diverting medium-weight packages on conveyor lines, with the rear flange providing a rigid fixed mounting point.
Delivers consistent clamping force for jigs and assembly tools. The built-in magnet allows sensors to confirm full extension and retraction for automated quality control sequences.
Used in logistics sorting systems to push cartons onto branch conveyors. The FB flange simplifies mounting to a bulkhead, while the adjustable cushion ensures quiet operation at high cycle rates.
For applications requiring more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, more compact footprint is needed, the 40 mm bore offers 628 N. The 500 mm stroke on this 50 mm bore is within the standard maximum of 1200 mm, but any side loading at this extension must be managed with an external guide rail to prevent rod bending and premature bearing wear.
To ensure a correct direct replacement, match five key points: the 50 mm bore, 500 mm stroke, PT1/4 port thread, the FB rear flange mounting accessory, and the -S magnet option for sensor compatibility. This cylinder is a direct replacement for another AirTAC SC50X500SFB or an equivalent tie-rod cylinder with identical specifications.
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, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
It is a direct replacement only for another AirTAC SC series tie-rod cylinder or a compatible tie-rod design with identical specifications. The SC series is not an ISO 15552 profile cylinder and has a shorter body length, so it is not dimensionally interchangeable with ISO 15552 cylinders. Always match the bore, stroke, PT port thread, FB rear flange mounting, and -S magnet option.
