A bearing arrangement, for example, for a variable pitch propeller, has a fluid operated actuator (42, 34, 40) for causing relative movement between bearing surfaces of races (12, 32) so as to preload bearings (30) held therebetween. Mechanical locking means (34, 36, 38) is provided to maintain the bearings under preload when the fluid pressure is released from the actuator. |
