Abstract: A spring system for resiliently supporting a mass with respect to a base comprises a supporting member mounted for movement and which can be coupled to the mass and is bounded by a portion of a spherical surface which bears against a concentric complementary guiding spherical surface fixed with respect to the base to guide the supporting member to rotate in all directions around the center of the sphere. A circular resilient device is provided in engagement with the supporting member and is supported with respect to the base. The supporting member is coupled to the mass at a point inside the circular resilient device whereby the supporting member is tilted by radial shocks while its spherical surface is guided along the guiding spherical surface and by the deformations of the resilient device as a result thereof, a resilient couple and/or a radial resilient force is developed which tends to move the supporting member into its initial position.

Abstract: A slide bearing in which at least one element of rubber or rubber-like material having projections thereon is introduced into the housing of the bearing with clearance and wherein this clearance is closed and the bearing race connected to the housing, by pressing the projections inwardly into the housing and holding them in expanded condition.
