CEMA Ceramic Hanger Bearings

Crown Industrial now offers Conveyor Equipment Manufacturers Association (CEMA) standard dimension and tolerance hanger bearings. These ceramic hanger bearings are made from Y-TZP Zirconia, a formulation that provides some of the toughest, strongest and longest-lasting ceramics available. It can also be up to 40% stronger than Mg-PSZ material and is manufactured to give a very fine microstructure and minimal grain boundary phase, ensuring extremely long life times and in-service quietness.

Zirconia ceramic hanger bearings provide a range of benefits:

  • Major increase in bearing life
  • Increase in life of journal and shaft, with a significant reduction in galling
  • Potential noise reduction in many applications
  • Option to use ceramic liner or replace only bottom bearing
  • Manufactured to CEMA standards
