What’s the advantage of a lemon tube over a triangular tube in a farm driveline component?<\/strong><\/p>\nThe lemon profile’s curved surfaces reduce stress concentration at contact edges, which can extend tube life in applications with frequent angular changes. It also tends to be easier to clean than a triangular profile because soil doesn’t pack into sharp corners.<\/p>\n
