A bearing can only perform to its full capacity when it is correctly fitted on the shaft and in the housing. Conversely, improper bearing fits, too loose or too tight, can lead to undesirable operating conditions and early failure.
Problems with fits that are too loose include, damage to the bearing seat, excessive wear, noise, vibration, and reduced rotational accuracy. Problems with fits that are too tight include reduction in radial play, overheating, unintended preload, and heavy mounting forces (or dis-mounting) are required.
