Abstract: A self-centerable bearing retaining a spherical, porous bearing between a metal receiving and metal pressing plate in which the plates are integrally connected by a binder; one side of the spherical surface of the bearing being received in a corresponding portion of the metal receiving plate and an annular pressing and supporting portion of the pressing plate loosely receiving a spherical portion of the bearing, the annular pressing and supporting portion including a plurality of projections engaged in a plurality of corresponding grooves on the bearing, an annular flange portion on the inner peripheral surface of the pressing plate including projections engaged in a plurality of sloped recesses on a peripheral edge of the metal pressing plate.

Abstract: In this bearing for light rotary shafts, a metal receiving plate provided with a hemispherical recess of a diameter slightly larger than the outside diameter of a spherical bearing metal is formed, an annular felt impregnated with a lubricating oil is fitted to said metal receiving plate, the intermediate periphery of the spherical bearing metal is fitted to said annular felt, further an annular metal pressing plate having the edge part of an inner hole formed to be of an arc of a diameter slightly larger than the outside diameter of the spherical bearing metal is placed on said annular felt, the spherical bearing metal pressing plate by leaving a very slight clearance between it and the arc of the inner hole of said annular metal pressing plate and between it and the hemispherical recess of the metal receiving plate and the metal receiving plate and annular metal pressing plate are integrally combined with each other by filling an annular groove formed of the peripheral edge step part of the annular metal pr
