Success Story
Industry: Automotive Production
Application: Exhaust Ventilation Application
Cost Savings: $16,035
Introduction
An international car manufacturer was experiencing increasing temperatures of their Spherical Roller Bearings in an exhaust ventilation application. NSK was asked to find a solution in order to reduce temperature generation. NSK Engineering carried out an Application Review including a temperature survey revealing high preload leading to significant temperature rise. NSK Spherical Roller Bearings were suggested along with training of staff on proper installation in order to reduce reoccurance. A bearing trail was conducted, resulting in a considerable temperature reduction.
Key Facts
- Exhaust Ventilation Application
- Temperature increase causing early bearing failure
- NSK’s solution: Using NSK Spherical Roller Bearings along with training.
- No temperature rise and therefore no bearing failures in over 12 months
- Productivity improvement
- Exhaust Ventilation
- NSK Spherical Roller Bearing
Value Proposals
- NSK engineering conducted a Bearing Failure Analysis showing high bearing preload leading to temperature rise
