The quest to stop the fake bearings industry continues apace at NSK, where the recent seizure of counterfeit NSK packaging and labels in Hebei Province, China, illustrates the scale of the problem. More than 23,000 fake boxes and cartons, which were subsequently confiscated pending further investigation and potential prosecution, were discovered in Linxi County, Xintai City.
Depending on the usage conditions, if rotational load*2 is exerted on the bearing, a slip phenomenon called creep can occur between the housing and the bearing, which results in wear that can reduce the life of the bearing. In 2007, NSK launched its Creep-Free™ series of bearings of an inner diameter (ID) of 45 mm or smaller. This series has been very well received by our customers. In ...
NSK jointly with the local distributor performed a bearing failure investigation on site. The result showed that the lubrication of the pump bearings as the source of repeated failures. NSK proposed to change the bearing type over to a sealed for life greased bearing featuring DDU seals and high temperature grease. This gave significant improvement in performance reducing maintenance costs.

Hybrid bearings using ceramic balls are designed for applications where high grade electrical isolation is necessary and / or high speeds occur. The robust design together with a combination of steel and ceramics makes the bearings useful for many different applications. The bearing lifetime is extended because electrical corrosion can not occur and in high speed operation seizures are avoided.
NSK’s “New Bearing Doctor” publication is the ideal tool to assist factory managers and maintenance engineers in identifying and preventing bearing failures to avoid costly production downtime. The new, free publication is one of the most comprehensive of its type, running to thirty-five pages and divided into seven sections.
