Zusammenfassung:	By the contraction process in which the contraction die is made to displace a pair of inner spherical surfaces in the direction of approaching each other to deform plastically the outer race 1 in such a manner as the outer race 1 is followed along the spherical surface 2a of the inner race 2. And the releasing process in which, by a releasing device comprising a plurality of rollers, the outer race is rotated while the peripheral surface 1b of the outer race 1 deformed plastically being pressed by a plurality of rollers to release the internal stress of the outer race 1, the spherical bearing wholly made of titanium alloy is formed. Thus constituted, since a slide is generated between every ridge 6 of the outer race 1 and a pair of spherical surfaces, the outer race 1 is deformed plastically in such a manner as the outer race 1 is followed along the spherical surface 2a of the inner race 2, the spherical bearing wholly made of the titanium alloy for industrial use can be formed.
