Tapered roller and ball bearings are both an ______ design.

The key idea is that these bearings use rolling contact to carry loads, which greatly reduces friction compared with sliding contact. In ball and tapered roller bearings, loads are supported by small balls or rollers between the inner and outer races. This rolling action lowers friction and wear, so they’re classified as anti-friction bearings. Hydrodynamic bearings rely on a lubricant film to generate pressure to support the load, which isn’t how these rolling-element bearings primarily work. So, while they do bear loads, their defining design feature is the anti-friction, rolling-contact nature.
