Tangent keys are specially designed machine components used for the positive transmission of torque between a shaft and a hub. Unlike traditional keys, they are installed in pairs facing each other, thereby acting tangentially to the shaft surface. This unique design enables the transmission of high torque while simultaneously ensuring optimal stress distribution within the shaft. As a result, tangential keys are primarily used in heavy machinery and large-scale plant construction, where extreme mechanical demands are involved. That is why quality matters when purchasing tangential keys\u2014and this is exactly where we come in. As an experienced manufacturer in CNC machining, we have been committed to genuine quality since 1955. In addition to standardized tangent keys in accordance with DIN 268, we also offer custom-made products tailored to your specific requirements. A wide variety of materials is available from stock. Additionally, you can decide whether you need the tangent keys with or without heat treatment.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Tangential keys are wedge-shaped connecting elements with a rectangular cross-section that\u2014unlike most other keys\u2014are positioned tangentially to the shaft rather than radially. In everyday practice, two tangential keys are always used; they are positioned opposite each other and thus work together to transmit torque. They are manufactured in accordance with DIN 268, which defines the dimensions, wedge angles, tolerances, and arrangement. Installation and removal of tangential wedges are significantly more complex than with classic flat wedges or nose wedges; however, they are specifically suited for high-load applications and can also effectively transmit high torques. Torque is transmitted via positive engagement along the flanks of the two keys and is distributed evenly across the shaft due to the symmetrical paired arrangement. This prevents unilateral radial loading of the shaft and significantly reduces the notch effect compared to single keys. Tangent keys therefore offer a high degree of reliability even under fluctuating and shock loads.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
