Machine keys are essential mechanical components designed to secure rotating elements such as gears, pulleys, and couplings to shafts, ensuring efficient torque transmission and synchronous rotation. Available in various types, including parallel keys, Woodruff keys, taper keys, and Gib head keys, they cater to diverse industrial applications. Made from robust materials like carbon steel (S45C) and stainless steel (SS304), machine keys provide durability and reliability under varying load conditions. By fitting precisely into keyways, these keys play a critical role in maintaining mechanical integrity and performance, adhering to international standards like DIN 6885 and JIS B1301 for consistency and compatibility across different machinery and equipment  ▲ Close
