摘要： A rolling bearing having bearing rings and rolling members wherein at least one of the bearing rings and the rolling members essentially consists of an alloy steel which contains carbide-forming elements. The bearing rings and the rolling members are subjected to carburizing or carbo-nitriding and then hardening to form a rolling surface layer. The content of retained austenite (.gamma..sub.R vol %) in the rolling surface layer is from 20 to 45% by volume and the hardness (Hv) of the rolling surface layer reinforced by dispersion of fine carbides or carbonitrides with an average grain size of from 0.5 to 1.5 .mu.m with regard to the content of the retained austenite (.gamma..sub.R vol %) is within the range of:-4.7.times.(.gamma..sub.R vol %)+920.ltoreq.Hv.ltoreq.-4.7.times.(.gamma..sub.R vol %)+1020.

摘要： A dynamic pressure type bearing comprising an outer cylindrical member made of metal and a thin walled inner cylindrical member made of synthetic resin and joined to the inner periphery of the outer cylindrical member. The inner periphery of the inner cylindrical member is formed with a plurality of grooves for generating dynamic pressure. The thin walled inner cylindrical member is joined to the inner periphery of the outer cylindrical member during the moulding time by a joining means. The method of making this bearing consists of the steps of: firstly, inserting an outer cylindrical member previously provided with suitable joining means into an outer mould; inserting an inner mould provided with projections into the outer mould; pouring or injecting molten synthetic resinous material into a gap formed between the outer cylindrical member inserted in the outer mould and the inner mould already placed in the outer cylindrical member; and allowing the poured resin material to solidify to form an inner cylindrical member integrally joined to the outer cylindrical member to constitute a composite bearing of laminated outer and inner cylindrical members. The composite bearing is removed from the moulds by moving it in an axial direction away from the moulds. Preferably, the synthetic resin for forming the inner cylindrical member is a thermosetting resin.
