The programme is simple to implement, and is broken down into stages in order for people to understand it easily. This makes it logical for end users to buy into and understand the process; and it shows them how NSK can add value to their businesses. The process often starts with a site survey, which is very detailed. NSK engineers visit a customer’s premises, talk to them; get to understand what their difficulty is, and then work out what NSK can do to support them.
As part of the Cost Saving programme, all aspects of a company’s operations, including systems, stock, specific problem applications, lubrication, and even training issues are audited. A lot of the time is spent questioning, understanding and listening; this is crucially important because if this stage is not right, then anything that follows won’t work.
An analysis of the data acquired is then performed and this leads to recommendations for improvements.
In practice, these recommendations could relate to training: about how to examine or look after bearings; how to spot failure modes; and how to handle bearings correctly - as this is one of the biggest causes of premature failure. In addition, NSK might need to look at the lubrication of bearings; or recommend part substitution for a bearing that would work more effectively. The overall aim is to get to a stage where NSK can document the value that it has delivered, by proving how much money has been saved as a result of adopting Cost Saving solution. This provides management with firm figures that give them reassurance that they have saved money and improved profitability by working with NSK.
Value of Cost Saving Programme Evidenced by Savings of €35.786 Per Annum.
The value of NSK’s Cost Saving programme as a cost reducer is evidenced by an early application of the technology, where a confectionery manufacturer was experiencing short bearing life on a conveyor line carrying boiled sweets. The installed bearing units were lasting just 3- months due to ingress of water and sugar on wash down, and these failures were resulting in costly downtime.
NSK recommended changing the existing bearings for Molded-Oil™ ball bearings, providing over 1- year life compared to the current units. This change was implemented on the conveyor line and downtime was reduced dramatically. As a result, planned maintenance and any bearing replacement can now be carried out during the yearly shut down period.
