23 times longer service life achieved with CeramicSpeed Bearings

Plastic dust was one of the huge challenges that threatened the service life of the bearings at one of Europes leading plastic manufacturers.

Problem

Mounted in ovens where the plastic film is extruded 24 hours a day, the bearings are facing a harsh environment, where the temperature varies between 150ºC170ºC. This along with an average of 12-15 start/stop per minute, followed by vibrations makes it very difficult for conventionally steel bearings to last more than 2 weeks.

Solution

CeramicSpeed LongLife HighTemp bearings with ceramic balls have a low coefficient of thermal expansion – only a quarter of that of steel balls – and don’t microweld to the races. These properties means that our bearings can be used with a lower degree of play compaired to other high temperature bearings, improving their function at high RPM.

Result

After implementing CeramicSpeed HighTemp bearings the company has achieved a bearing life which is 23 times higher compaired to conventionally bearings. This along with no machine crashes caused by bearings, has increased efficiency and reduced maintenance costs a lot. So in spite of higher purchase price of hybrid bearings the investment is recovered already when the bearing service life has been extended by only 2 to 3 times.

Technical Highlights

  • Harsh environment with plastic dust and vibration
  • Many start/stops per minute
  • Bearing temperature: 150ºC-170ºC
  • Lubrication: special customized
