Faerch Plast A/S

Faerch Plast A/S is one of Europe's leading plastic manufactures with annual turnover of more than 100 Million Euros. The company is situated in Holstebro, Denmark.
In August 2004 CeramicSpeed paid Faerch Plast A/S the first visit. In some heat ovens the company had problems with extremely short bearing life. Every 2 weeks the service team had to change bearings.

 

The application is common among the heat ovens available on the global market. An electrical motor is pulling a shaft, which pulls 50-meter plastic foil through 17 rollers. This will give the foil a temperature at 140 °C before entering the adaptation machinery.

Some of the most important reasons for the short bearing life are: 12-15 starts/stops pr. min, operating temperature between 150 °C and 170 °C, no air circulation, vibrations, and plastic-dust contamination.

The original solution with SKF greased bearings (6004 2RZ/C3) lasted 2 weeks - running 24 hours a day - before breakdown. Before the bearings can be changed the oven must cool down. Normally the down time period is 6-7 hours. It only takes 2 hours to replace the bearings.

Late August 2004 the first hybrid bearings was delivered and CeramicSpeed guaranteed 8 weeks lifetime - 4 times longer bearing life.
 

Already during first test period the hybrid bearings showed their worth. After 14 weeks of testing without a single break down, the service team decided to check the bearings - no signs of fatigue or wear. The hybrids looked like new and therefore Faerch Plast A/S decided to continue with the hybrids. 2nd November 2005 - the hybrid bearings from August 2004 are still running.
CeramicSpeed has delivered several hybrids since and the 2nd generation has a new cage and special grease. Those hybrids are expected to last 60 - 80 weeks.

 

In heat ovens at Faerch Plast A/S CeramicSpeed bearings reached 30 times longer service life

When Faerch Plast A/S first heard about the price difference, they were surprised - 20 times more expensive compared to standard steel bearings. But already after 2-3 times longer bearing life, there was return of investment. Further Faerch Plast A/S has ordered the manufacturer of the heat oven to use hybrids as a standard in the future.
