The most frequently used roller bearings are single row deep groove ball bearings. The balls are held apart in a cage, each guided by a deep groove on the inner and outer ring. In addition to absorbing radial loads, this also enables a low absorption of axial forces. Because deep groove ball bearings are so versatile, designed for high to very high speeds and relatively hard-wearing, consequently there are many series available – metric, inch, double row and reinforced. “Miniature bearings” (as they are often called in Switzerland) are very small low-maintenance deep groove ball bearings with an internal diameter not exceeding 10 mm. This simple ready-to-mount unit comprises an inner and outer ring and a cage with balls. Optionally available as open or covered versions.
