B630/7 Single Bonded Torsion Bush


This type of bush has both chemical bond (inner tube only) and interference fit with the outer tube.  The interference fit provides for pre-stressing of the rubber making it stiffer for normal radial, conical and torsional loads.  It is not intended for use in high axial loading situations.                                        

One advantage of this bush type is that occasional extreme torsional overloads can be accommodated since the bush will slip within the outer tube under these conditions.
