Ball bearings - KVK
Ball bearings consist of an inner and an outer ring with a row of balls positioned between them. The balls are usually held in place by a cage, which ensures correct spacing and prevents contact between the balls. There are also full complement designs without a cage, allowing for more balls to be used and thus increasing load capacity. Ball bearings can accommodate radial, axial, or combined loads, depending on the application. They are suitable for higher speeds compared to roller bearings but have a lower load-carrying capacity. Versions are available with and without seals. Sealed bearings provide protection against contamination and require minimal maintenance, while open types allow for more flexible lubrication under specific operating conditions.
