Abstract

Abstract A construction of the separating surfaces of a split bearing with bores for receiving the cover bolts, in which two adjacent separating surfaces of different bearing parts are inclined to one another when the bearing bolts are not yet tightened, in such a manner that these surfaces subtend an angle of relatively slight magnitude, as viewed in cross section.
