The AirTAC SC50 Standard Cylinder SC50X490 is a genuine double-acting standard air cylinder with a Ø50mm bore and 490mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X490 is a 50 mm bore, 490 mm stroke double-acting pneumatic cylinder from the SC tie-rod family. It generates a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator for linear motion tasks.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 pneumatic ports. The total extended body length is approximately 640 mm, calculated from the 150 mm body length A plus the 490 mm stroke. Standard TPU seals provide a working temperature range of -20 to +70 °C, and the integral adjustable air cushion helps decelerate end-of-stroke impact.

Provides the 982 N push force at 0.5 MPa needed to divert medium-weight packages off a conveyor line, with the 490 mm stroke offering ample reach across wide belt sections.
Delivers up to 1767 N of force at 0.9 MPa for pressing bushings or bearings into housings, where the 490 mm stroke accommodates deep component insertion on an assembly station.
The 490 mm stroke is well-suited for actuating a bin tipper to dump parts into a hopper, using the cylinder's 825 N pull force at 0.5 MPa to return the bin to its upright position.
For applications requiring slightly less force in a more compact body, the 40 mm bore SC40 series provides 628 N of push force at 0.5 MPa. If higher force is needed, stepping up to the 63 mm bore SC63 delivers 1559 N at the same pressure. When replacing an existing cylinder, ensure a match across five key points: 50 mm bore, 490 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a built-in magnet.
With a 490 mm stroke, the unsupported piston rod is susceptible to bending under side loads. For this stroke length, it is recommended to use external linear guides or rod supports to prevent rod bearing wear and ensure smooth operation, rather than relying on the cylinder rod alone to bear transverse forces.
Quick checklist
At the standard operating pressure of 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.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a comparable ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It should only replace another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT ports, and basic mounting.
