Success Story
Industry: Car Wash
Application: Rotating Unions
Cost Savings: € 11 932
Introduction
A modern car wash in Germany cleans more than 110,000 cars p.a. The rotating unions for the washing heads failed due to ingress of water - the grease had been washed out. The maintenance was carried out by in-house staff. NSK identified that the current DGBB's were not suitable for this purpose. NSK proposed to change from the existing VV sealing arrangement, to Molded Oil bearings with DDU seals. After this change the bearings rotation unions were running without any problems.
