Introduction

An international car manufacturer experienced increasing temperatures of their Spherical Roller Bearings in an exhaust ventilation application. NSK was asked to find a solution to this problem in order to reduce temperature generation. NSK Engineering carried out an Application Review including a temperature survey revealing high preload leading to significant temperature increase. NSK suggested using NSK Spherical Roller Bearings. In addition NSK recommended a Training “Application of NSK Bearings”. A trail was conducted, resulting in a considerable temperature reduction.

Key Facts

  • Exhaust Ventilation Application
  • Temperature increase leading to early bearing failure
  • NSK’s solution: Using NSK Spherical Roller Bearings.NSK Training “Application of NSK Bearings”
  • No temperature increase and therefore no bearing failures for more than 12 months
  • Productivity improvement
  • Cost saving generated
  • Exhaust Ventilation
  • NSK Spherical Roller Bearing

Value Proposals

  • NSK engineering conducted a Bearing Failure Analysis showing high bearing preload leading to temperature rise
  • A trail was agreed which resulted in an increase of bearing life from 6 month to over 12 months
  • The implementation of the NSK recommendations has been supervised by the NSK engineering team
  • The customer benefited from increased productivity and reduced maintenance costs
  • No bearing failure for over 12 months
  • Cost saving was realised
