Introduction

A customer in Central America, in the Quarrying and Mining industry, was experiencing reliability problems due to recurring bearing failures in its vibrating screens. The existing bearings failed after only 8 months. NSK engineers worked closely with the customer, analysing the failure, and recommended the VS series of bearings, designed to withstand aggressive operating conditions.

Spherical Roller Bearings, SRB, Long Life, VS, Foto Japan, 874x555
  • Spherical Roller Bearing - Vibrating Screen Series

Key Facts

  • The bearings work in a vibrating screen under the severe environment of vibration and contamination
  • The bearings failed every 8 months
  • This caused production stoppages of more than 8 hrs for each bearing failure
  • NSK engineers analysed the application together with the customer in order to increase the reliability of the application
  • NSK recommended the use of Spherical Roller Bearing - VS series which are designed to withstand aggressive operating conditions
  • After NSK bearings VS series had been installed, the application bearing life that bearing life was increased twice
