## Abstract

A stabilizer adhesive bearing for a vehicle stabilizer may comprise an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer. The resilient inner contour of the annular sleeve may comprise on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume. The three-dimensionally structured surface has a maximum roughness depth (Rmax) greater than 45 μm and a core roughness depth (RK) of at least 65% relative to the maximum roughness depth (Rmax) of the three-dimensionally structured surface. The maximum roughness depth (Rmax) is a total of the reduced tip height (Rpk) and the reduced groove depth (Rvk). Further, the reduced tip height (Rpk), the reduced groove depth (Rvk), and the core roughness depth (RK) may be determined in accordance with EN ISO 13565-2: December 1997.

## Claims
