Elastomeric bush bearing and process for manufacturing same

A process for manufacturing an elastomeric bush bearing designed as a slotted bush, the process comprising:

• providing a cylindrical metallic inner part and an axially slotted one-part or multipart outer sleeve for concentrically surrounding said inner part, said outer sleeve having a central surface, said cylindrical inner part having an outer inner part surface, said outer inner part surface defining a first inner part section having a first inner part radial dimension and a second inner part section having a second inner part radial dimension, said first inner part radial dimension being less than said second inner part radial dimension, said first inner part being located at an axially central area of said inner part;
• surrounding said metallic inner part with the one or more parts forming said outer sleeve;
• injecting an elastomer between said inner part and said outer sleeve to form a bearing body such that said bearing body is adheringly connected to and between said inner part and said outer sleeve in a vulcanization process to form an non calibrated bearing;
• calibrating the non calibrated bearing by reducing the diameter of said outer sleeve, wherein the one or more parts forming said outer sleeve of the bearing are beaded at one axial end and another axial end of said outer sleeve before they are connected to the other components of the bearing such that a radial dimension of said outer sleeve at said one axial end and said another axial end is less than a radial dimension of said outer sleeve at said central surface section, said first inner part section of said inner part being located between said one axial end and said another axial end.
