The number of bearings provided in the design of the reel. Bearings are used to reduce friction of rotating parts, which, on the one hand, protects such parts from wear, and on the other hand, reduces excessive effort expended when the handle is rotated. Accordingly, the
more bearings, the more friction units are protected and the better the coil is “optimized”; this parameter is a good indicator of the overall class of the product. At the same time, it is necessary to evaluate different models taking into account their purpose (see "Type").
So, in fly fishing reels, even quite expensive ones, 1 bearing is usually provided — at the point of installation of the drum on a bracket designed for attachment to the rod. This is actually the only significant friction point, so more bearings are simply not required. For multiplier reels, this number varies from 1 for relatively simple options to 6 – 7 for premium ones. And in inertia-free bearings, the number of bearings can reach a couple of dozen.
