The AirTAC SC50 Standard Cylinder SC50X755 is a genuine double-acting standard air cylinder with a Ø50mm bore and 755mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X755 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 755 mm stroke. At 0.5 MPa it generates 982 N of push force and 825 N of pull force, rising to 1767 N push at the maximum operating pressure of 0.9 MPa. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration for this extended-stroke unit.
With a body length A of 150 mm, the total extended length reaches approximately 905 mm. This specific model is a non-standard stroke, built to order beyond the standard 1200 mm maximum for the 50 mm bore. It features the default TPU seals for a -20 to +70 °C operating range and standard PT1/4 threaded ports.

The 755 mm stroke is ideal for pushing or pulling products across wide conveyor gaps or into packaging stations where a long, controlled linear motion is essential.
Delivers consistent 982 N clamping force at standard line pressure, suitable for holding large components in place during welding, gluing, or mechanical fastening operations.
Used in agricultural machinery for remote gate opening, chute directing, or implement positioning, leveraging the robust tie-rod construction and reliable TPU seals.
For applications needing slightly less force, the 40 mm bore SC40 series provides 628 N push at 0.5 MPa. If higher force is required, stepping up to the 63 mm bore delivers 1559 N at the same pressure. This 755 mm stroke requires careful attention to side loading; long, unsupported piston rods are susceptible to bending under lateral forces. Always use an external guide system or ensure the load is perfectly axial to protect the rod bearing and seals.
When replacing an existing cylinder, confirm five key points for a direct match: 50 mm bore, 755 mm stroke, PT1/4 port thread, the specific mounting accessory (this is a basic body, so no brackets are included), and the absence of a built-in magnet. This ensures the new unit will fit the existing plumbing and machine interface without modification.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force for the 50 mm bore is 1374 N. The pull force on the retract stroke at the same pressure is 1155 N, accounting for the 20 mm rod diameter.
No, 755 mm is a non-standard stroke for the 50 mm bore, which has a maximum standard stroke of 1200 mm. For any stroke over 300 mm, you must prevent side loading. An unsupported rod of this length will bend if lateral force is applied, so install an external linear guide or rod support to ensure longevity.
