Article

Two common scenarios that service centers deal with regarding belt drive applications are failure of a motor drive end ball bearing or breakage of the shaft at the drive end bearing shoulder. The cause of these failures often is over-tensioning of the v-belts. However, there are many other faults or undesirable practices that can lead to premature bearing failure, belt wear and sheave wear.  Due to practical space limitations, this article isn't exhaustive in its coverage but deals with common scenarios other than motor bearing failure and shaft breakage.
