“PRESTRESSED BUSHES” with turned down sides:
For the same dimensions, this type of bush provides a radial load capacity which is superior to that of the classic “prestressed”.
In addition, versions of relatively short length permit conical movement more easily (reduced torque and increased angle).
This takes the form of a rubber sleeve whose external surface is a truncated, and which surrounds a cylindrical internal part to which it adheres strongly by high radial expansion.
Assembly in pairs, in a housing made up of two truncated cones placed small end to small end.
By axial pressure, a high compression is created which ensures the external adherence of the rubber and causes lateral cushions to form at each end of the housing. These cushions ensure resistance to axial forces.
