摘要： Provided is a rolling bearing using a retainer, particularly a highly reliable retainer in which dimensional stability required for a retainer of an outer ring guide type, ductility required for a crown-type retainer, improvement in adhesion of grease with a poly-α-olefin oil or the like as a base oil, and deformation prevention at a high speed can be achieved. The rolling bearing includes at least an inner ring 1, an outer ring 3, a synthetic resin retainer 9, and a rolling element 7, in which the synthetic resin retainer 9 is formed of a polyamide resin composition including polyamide 410 and a reinforcing fiber material with a content of 0% by weight to 40% by weight.

摘要： The present disclosure provides a deep groove ball bearing with a split cage, including an outer ring, an inner ring, steel balls, an upper frame body, a bearing frame, and a lower frame body. Pocket grooves are formed in the bearing frame. The bearing frame is provided with a connecting piece. A first insertion groove and a second insertion groove are formed in both side walls of the connecting piece. A connecting groove is formed in a bottom surface of each of the pocket grooves. An oil storage cavity is formed in the upper frame body. The oil storage cavity is provided with a positioning flange at an opening. The positioning flange is in insertion fit with the connecting groove. The lower frame body is provided with arc-shaped grooves at positions corresponding to the pocket grooves. A connecting seat is formed on the lower frame body. A first insertion member and a second insertion member are arranged on the connecting seat. The first insertion member is in insertion fit with the first insertion groove. The second insertion member is in insertion fit with the second insertion groove. Ends of the first insertion member and the second insertion member are provided with positioning members. The upper frame body is provided with positioning holes configured for insertion with the positioning members. The deep groove ball bearing has an overall structure convenient for installation, higher stability, and improved use effects, production and processing efficiency.

摘要： A retainer made of a synthetic resin for use in a deep groove ball bearing is proposed of which the lubricity has been improved. The retainer includes a cylindrical first split retainer member (41) having a first axial side, and a cylindrical second split retainer member (42) having a second axial side coupled to the first axial side of the first split retainer member (41). Circumferentially spaced apart first and second cutouts (45 and 50) are formed in the first axial side of the first split retainer member (41) and the second axial side of the second split retainer member (42), respectively, which define respective pockets for receiving balls with the split retainers (41 and 42) coupled together. A coupling arrangement (X) is provided between the first and second split retainer members (41 and 42) which is adapted to engage the split retainer members (41 and 42) when the split retainer members (41 and 42) are coupled together, thereby keeping the split retainer members (41 and 42) axially inseparable from each other. With the retainer mounted in a deep groove ball bearing, when the outer race (11) and the inner race (21) rotate relative to each other, since the first and second split retainer members (41 and 42) rotate at different peripheral speeds due to a difference in diameter therebetween, pumping action is produced in the bearing, which causes a forced flow of lubricating oil in the bearing.
