RESIN CAGE, TAPERED ROLLER BEARING USING THE SAME, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin cage configured to prevent tapered rollers of a tapered roller bearing from coming off from the elastic resin cage which is likely to be deformed by weights of the tapered rollers to deform cage pockets, while improving assembling or disassembling workability.SOLUTION: A resin cage includes a small-diameter ring part and a large-diameter ring part, and a plurality of column parts arranged therebetween. Tapered rollers are held between the column parts. The small-diameter ring part or the large-diameter ring part, or both of them have circumferential grooves. Preferably, the grooves are provided for mounting the ring parts.
