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.

NSK has updated its Solutions App to feature information that helps engineers understand the added value that can be achieved through the adoption of NSK bearings and associated services.

When a global manufacturer of bus gearboxes was unexpectedly faced with having to replace roller bearings in a series of helical transmission gears due to failures within the warranty period, NSK was invited to assess the cause of failure and suggest a solution.

A compact, 48-page booklet has been published by NSK that explains bearing designations in concise and clear terms, thus making it easier for engineers to choose bearings and order spare parts.

Michael Preinerstorfer, the recently appointed Managing Director of the European Industrial Business Unit (EIBU) at NSK, explains how he is aiming to extend further the company’s position of strength through superior added value for customers. In fact, NSK’s AIP added value programme, is already driving huge benefits and savings at customers worldwide, largely through a commitment to 100% in-house product development, extensive service provision and a pledge of total quality. Mr Preinerstorfer also emphasises on the relevance of next year’s centenary celebrations, and reveals that the company’s turnover target for 2016 is 7 billion euros.

Faced with high maintenance costs relating to bearings on a plate rolling mill, a major steel manufacturer has witnessed significant benefits following an application specific product replacement from NSK. Until recently, a daily maintenance routine was required on the rolling mill’s existing open roll bearings to ensure sufficient lubrication. However, analysis by NSK led to the proposal, and subsequent installation, of advanced Sealed-Clean bearings, which are designed specifically for use in heavily contaminated environments and offer 2.7 times longer life than conventional roll neck bearings.

Designed specifically to suit steel industry converters and continuous casting lines, optimised cylindrical roller bearings from NSK deliver benefits that include the use of up to 30% wider cylindrical rollers for accommodating greater loads. The bearings also provide longer replacement intervals, helping end users reduce downtime.

Twice as durable as previous generation models (LH/LS series), the new NH/NS linear guides have the same dimensions but feature a 30% higher basic dynamic load rating thanks to geometrically optimized ball grooves. They also support up to three times higher maximum speeds, from 150 to 300 m/min.
