Ball and sleeve bearings: characteristics
Ball bearing
· well suited for high radial and axial loads
· well suited for all operating modes, for start-stop and reversing operation
· on larger motors
· more audible noise if not preloaded
· when preloaded higher friction
· more expensive Sintered sleeve bearings
· suited for low radial and axial loads
· suited for continuous operation at higher speeds
· smaller motors
· low friction and noise
· cost effective
· not suited for start-stop operation
