Abstract
The invention concerns a ball bearing comprising two rows of ceramic balls (1) and with oblique contact between two substantially back-to-back inner ball bearing tracks, on an outer steel ring (2) and outer ball bearing tracks substantially facing each other, on inner half-rings (4 and 5) capable of being axially preloaded against each other, the tracks of the outer (2) and inner (3) rings being coated with an alloy coating based on dense chromium co-operating with the ceramic of the balls (1) to provide the ball bearing with excellent rigidity, protection against corrosion and tribological behaviour under load, and a reduced global volume, thereby considerably reducing degradation of the lubricating grease and maintenance costs. The invention is applicable to large diameter preloaded hybrid ball bearings, to absorb axial loads, and in particular for equipping swashplates of helicopters.
