Success Story
Industry: Textile and Leather
Application: Belt washer
Cost Savings: € 9.000
Introduction
An international manufacturer of technical textile products was experiencing frequent bearing failure on a belt wash application. NSK carried out a Bearing Failure Analysis revealing ingress of water and chemicals leading to the bearing failures. NSK was asked to find a solution to this problem. A trail was agreed which resulted in an increase of bearing life.
Key Facts
- High volume belt cleaning and inpregnation line
- Water ingress
- NSK’s solution: replacing standard ball bearing with NSK’s Molded-Oil ball bearing
- No bearing failures for more than 12 months
- Productivity improvement
- Cost saving generated
- Belt washing application
- Molded-Oil Bearing
Value Proposals
- NSK engineering conducted a Bearing Failure Analysis showing ingress of water and chemicals into the bearing
- NSK required to replace the standard ball bearings with ball bearings Molded-Oil
