A paper mill in the US was facing frequent bearing failures on a Nip Roll. The bearing failed after just 1 year of service, which created a high cost of lost production together with significant maintenance issues.
NSK was consulted to investigate and found out that the bearing design and set-up were not appropriate. After the installation of NSK's recommended Spherical Roller bearing, no more failures occured.
