Condition monitoring of critical calender roller bearings prevents costly production stoppages

摘要

With more than 30 manufacturing locations in over 20 countries worldwide, the Renolit Group is a leading global producer of high-quality plastic film and related products for technical applications.Repeated rolling bearing failures on various calender units at the production plant in Worms, Germany, were causing unplanned downtime and costly production stoppages. Schaeffler was given the task of developing a monitoring concept that would improve the overall availability of the facilities. The challenges included the very slow roller speeds, high housing temperatures (up to 150°C) and the difficulty of accessing the measurement points during production.
