DID YOU KNOW? L10 life is the number of revolutions or hours that 90% of a group of apparently identical bearings will complete or exceed before fatigue is expected to occur. In other words, 10% of the group is not expected to achieve the L10 life.

A Tip to Extend Motor Life in Harsh Environments
Siemens and Decatur Industrial Approve Modification for Application
Front covers on IEEE841 motors are there for air flow. However, in some industries such as grain, paper and other highly contaminated environments the front covers collect product and do the opposite of what they are intended.
In this situation, a Decatur Industrial customer had several IEEE841 motors. These motors provide exceptional quality with the desired inpro/seals. The drawback was that the motor was constantly plugged up with product debris. The back fan cover can be removed and cleaned but the front cover is a solid circle and cannot. In most situations, this is fine, but in some unique harsh environments this causes quality issues.
The customer wanted to keep the features of the IEEE841 but eliminate the front bearing premature L10* life they were getting with the front covers in place. Decatur Industrial consulted with Siemens to approve the front covers being removed from newly purchased and repaired IEEE841 in this application.
