A leading manufacturer of seeding machines experienced bearing failure problems with their seeding discs of their Precision Seed Drills. After 500ha use they experienced nearly 100% failure rate, from clearance to loss of the whole seeding disc. After investigating the failed bearings, NSK found entry of dirt and contamination as the cause for the failures. NSK suggested an improved seal for the bearing with the same outer dimensions so that the customer did not have to change their design.
NSK proposed a double lip seal specifically developed for applications in these types of harsh environments. With this solution the lifetime was improved by at least 3 times, which saved the customer not only material costs but also several service hours to replace the failed bearings.
|Annual bearings replacement cost savings||$58,131|
|Maintenance cost reduction||$5,285|
