Abstract:

Bearings have been playing a pivotal role in the operation of efficient industrial machinery right from the industrial revolution. However, their may be premature bearing damages before installation which can be attributed due to many assignable causes. If a bearing has any kind of nick or damage, it may lead to rejection by the potential customers.

The purpose of this study is to determine quantitatively the various reasons of nick formation in a bearing industry. To accomplish this, a leading ball and taper roller bearing manufacturing industry in northern India has been selected and study was performed with the above mentioned objective. The data was collected using data collection sheets along with personal observation and visual inspection. The study revealed that nearly 6% to 12 % bearing
components were encountered with the problem of nick formation which is substantially high as regards industrial quality standards are concerned. It was found that three prominent nicks occur in the bearings namely face nick (back or front), rib nick and race nick. The study proposes corrective actions and necessary handling techniques which may lead to lower rejection rate by potential customers. This in turn will help the select industry (and other similar bearing industries) to increase their overall productivity and business performance as well.
