This shock-absorbing bearing comprises a bearing block (1), a pierced jewel (3), an endstone (4) and a shock-absorbing spring (5) connected to said bearing block (1) by four linking arms (5a1, 5a2, 5a3, 5a4), parallel to a plane containing the pivot axis (X) of said bearing and forming two suspension elements (5a1, 5c1, 5a2; 5a3, 5c2, 5a4), each having two of said linking arms connected to each other by a branch in the form of an arc (5c1, 5c2) centered on said pivot axis (X) and having a radius greater than that of said endstone (4), these suspension elements being connected to each other by two diametric arms (5e) located on either side of a central support element (5d). The outer ends of said diametric arms (5e) are connected to two of said linking arms (5a2, 5a4) belonging to said respective suspension elements (5a1, 5c1, 5a2; 5a3, 5c2, 5a4).
