Bearings for the Petrochemical Industry - 5

Petrochemical industry 5 Companies in the Petrochemical Industry need bearings that are able to increase mean time between failures (MTBF), minimise costly downtime and reduce loss of productivity. The machine components used in this sector – such as pumps, compressors, electric motors and ventilators – are extremely sensitive. As a global supplier to the world’s leading manufacturers in these industries, NSK has the experience and expertise to help its customers manage their costs and improve production efficiency.

Bearings for the Petrochemical Industry - 6

6 Explicit requests demand precise solutions NSK is introducing a new series of bearings in order to increase mean time between failures (MTBF). This new series enables you to reduce your operating costs by improving bearing life for very sensitive equipment such as pumps. High-capacity deep-groove ball bearings The HR series of high-capacity deep-groove ball bearings features a special internal design, allowing for larger rolling elements than standard deep-groove ball bearings. However, the external dimensions remain the same, according to ISO standards. These new bearings increase...

Bearings for the Petrochemical Industry - 7

Petrochemical industry 7 Using HR deep-groove ball bearings saves a refinery more than € 27,000 a year A petrochemical refinery plant was experiencing recurrent failures of a cylindrical roller bearing in a critical centrifugal pump. The transition from belt drive to direct drive on the pump led to unexplained bearing failure, resulting in costly downtime. Thanks to the implementation of our Asset Improvement Programme (AIP), the problem was analysed and identified. In addition to providing high-quality products, it is also our duty to help make your machines more reliable by providing a...
