NSK has highlighted the relevance of its cost saving, bearing asset improvement programme (AIP) to all sectors of industry. By reducing downtime resulting from production hold-ups, the AIP has saved a manufacturer of luxury handbags #8364;636.371 in lost revenue.
The cause of the lost revenue was the frequent failure of bearings on the inking machines that coat the side faces of leather used in the handbags. The bearings were failing regularly, every 6 weeks on each machine, due to ink ingress, resulting in seizure. With 40 machines on site, the regular failures meant that the costs for lost production, replacement bearings and maintenance were huge.
NSK visited the site to investigate the problem. The current bearings used on the machines were open ball bearings. NSK recommended replacing these units with Molded-Oil™ sealed bearings to combat the ingress of the ink.
A highly effective lubricant, Molded-Oil™ offers more than twice the operating life of grease lubrication in contaminated environments. Moreover, the technology means that operating environments are kept free of grease
