Interrupting a continuous manufacturing process occasionally because of a bearing failure can be irritating, but when the failures become more frequent the costs in lost production start to mount up. For one large producer of fish products, repeated bearing failures on a heat exchanger unit demanded attention, which led to NSK delivering a huge annual saving through the installation of improved bearing technology.
Scraped Surface Heat Exchanger (SSHE) systems are designed to operate as part of a continuous process where fouling of the heat exchanger and the subsequent reduction in heat transfer efficiency, can be expected. The internal scrapers perform two roles by removing the material build-up and also mixing the product at the same time.
NSK offers the services of its experienced application engineers to examine the circumstances of a bearing failure, with the aim of improving reliability and efficiency. The Added Value Programme, AIP, aims to help to production and maintenance managers to understand the causes behind bearing failure and what steps can be taken to improve the situation.
In this particular case, the manufacturer of fish products had five heat exchanger units and was experiencing twelve bearing failures every year. Aside from the maintenance costs to repair the heat exchanger each time, it was the five hours of lost production time that focussed the attention of the production manager sufficiently to call-in NSK.
Engineers from NSK investigated the issue and conducted a failed bearing analysis which determined that both water and hard particles were contaminating the bearing and causing a breakdown of the lubricant. Considering the nature of the application and the demands of the process, NSK proposed a trial using its Molded-Oil deep groove ball bearings.
Molded-Oil technology has been developed by NSK to greatly improve the performance of bearings in terms of reliability by allowing maintenance-free operation. Molded-Oil bearings use an oil-impregnated resin cage to provide lubrication to the bearing. Although similar designs are used by other bearing manufacturers, NSK provides a lubricating oil content of more than 50% by volume, which is considerably more than the competition currently offer.
The trial period eventually ran to more than three years without the bearing showing any signs of requiring replacement. The performance of the trial bearing was more than sufficient evidence for the production manager to request the NSK solution to be installed across all five heat exchangers.
The annual savings made as a result of the decision to use NSK Molded-Oil bearings were significant. By avoiding any major loss of production, the company’s total savings were in excess of
