Key bars play a crucial role in numerous mechanical and industrial applications, ensuring the transmission of power and keeping parts in place. In particular, A4 stainless steel key bars in accordance with DIN 6880 are recognized for their precision and robustness.
A keyway is a rectangular-shaped metal piece inserted into corresponding grooves in two mechanical components to lock them together, thus allowing the transmission of torque and preventing relative movement between the parts.
The standard din 6880 specifies the dimensions, tolerances and materials of keybars. This standard ensures that key bars are compatible and interchangeable, ensuring efficient installation and operation in mechanical systems.
A4 stainless steel offers an ideal combination of corrosion resistance, mechanical strength and acid resistance, making it a preferred choice for keybars. Unlike A2 stainless steel, A4 stainless steel is also resistant to chlorinated and saline environments, making it suitable for more corrosive environments.
The main difference between A2 stainless steel and A4 stainless steel is their chemical composition and corrosion resistance. A4 stainless steel contains more chromium, nickel and sometimes molybdenum compared to A2 stainless steel, which gives it better resistance to chemical attacks, especially in aggressive marine or industrial environments.
Applications of an A4 stainless steel key bar
Power transmission
A4 stainless steel key bars are widely used in power transmission systems to attach shafts to hubs, gears and pulleys, allowing for efficient transmission of torque.
Industrial machinery
