Camshaft journal definition
WebA journal is the part of a shaft that rotates inside a bearing. As can be seen above, there are two types of journal on a crankshaft - the main bearing journals form the axis of rotation for the crankshaft, and the connecting rod journals are secured to the ends of the connecting rods, which run up to the pistons. WebAug 13, 2014 · McInnis: The primary benefit of raising the cam location in the block is that it provides increased clearance between the rotating assembly and the camshaft. This allows you to use much more robust components which provide higher strength and stability. For example, using a 4.000-inch stroke crankshaft to increase displacement in a small block ...
