The AirTAC SC50 Standard Cylinder SC50X295 is a genuine double-acting standard air cylinder with a Ø50mm bore and 295mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X295 is a double-acting pneumatic cylinder delivering 982 N of push force when supplied with 0.5 MPa air pressure, rising to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 295 mm stroke, this model uses a 20 mm diameter piston rod with M16x1.5 male threads for tooling attachment, and features PT1/4 pneumatic ports.
This tie-rod cylinder has a body length (dimension A) of 150 mm, resulting in a total extended length of approximately 445 mm. The adjustable air cushion, with a 21 mm cushion length, decelerates the piston at each end of stroke to reduce impact and noise. It is built with standard TPU seals for an operating temperature range of -20 to +70 °C.

Provides the 1767 N of end-of-stroke force at 0.9 MPa needed to reliably stop or divert packages on a conveyor line, with the 295 mm stroke offering ample reach across wide belt sections.
The 20 mm rod and 295 mm stroke suit clamping applications where a firm, controlled hold is needed. The adjustable cushion protects fixture components from shock at the end of the stroke.
Ideal for actuating sorting gates or pushing totes in warehouse automation. The tie-rod design allows for easy maintenance and seal replacement in high-cycle logistics environments.
For applications requiring slightly less force, consider stepping down to the 40 mm bore SC40 series, which provides 628 N of push force at 0.5 MPa. If your load demands more power, the 63 mm bore SC63 series offers a significant jump to 1559 N at the same pressure. This 295 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore, ensuring standard availability.
When replacing an existing cylinder, ensure a 5-point match: 50 mm bore, 295 mm stroke, PT1/4 port thread, basic mounting (no accessory brackets on this model), and no built-in magnet. The SC50 is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a direct replacement for that standard.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force on the retract stroke is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The SC50X295 is a double-acting cylinder that requires constant air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston rod can drift or move under load. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod brake.
