Polymer spacer 

Fretting corrosion between the backing ring  and the inner ring side face is caused by  journal bending during operation. This  corrosion not only causes foreign particles  to enter the bearing, but also increases axial  bearing clearance, resulting in reduced  performance and reliability. The development target was to avoid  fretting corrosion by changing the steel-tosteel contact between the backing ring and  the inner ring side face to steel-to-polymer  contact. The polymer spacer of reinforced  polymer material is clamped onto the  bearing components. Extensive field  experience confirmed the expectations. As a  result, longer maintenance intervals can be  scheduled. This design was first introduced  for compact TBU designs. Today, the  polymer spacer can be offered for nearly all  TBU designs and sizes.
