Savings at energy plant
14 June 2018
When a UK-based electricity producer was experiencing frequent breakdowns due to bearing failures in two industrial fan units, the plant requested the services of NSK to propose and implement a suitable solution.
As the free end bearing at the energy plant exhibited axial loading, NSK was able to attribute the root cause of the ongoing failures to incorrect bearing arrangement. High-capacity Spherical Roller Bearings within SNN Plummer Blocks were therefore recommended, along with correcting the fixing arrangement. NSK´s Spherical Roller Bearings use state-of-the-art materials that make them suitable for high speeds and loads.
Offering special ring tolerances to withstand vibration, shock loads and misalignment, the bearings are heat stabilised up to 200°C. Furthermore, high-capacity Spherical Roller Bearings were the preferred choice as the internal design is more reliable for direct-coupled overhung industrial fan units, thanks largely to inner ring ribs that provide better roller guidance.
