Claim:
A bearing assembly comprising: a full type tapered roller bearing; and a roller presser; wherein said tapered roller bearing comprises an outer ring having a tapered raceway having a minimum diameter at one end thereof and a maximum diameter at the other end thereof, an inner ring having flanges at both ends thereof and a tapered raceway extending between said flanges so as to radially oppose said tapered raceway of said outer ring, and a plurality of tapered rollers disposed between said tapered raceways of said inner and outer rings; wherein adjacent ones of said tapered rollers are substantially in contact with each other, and a space is defined by said tapered raceway of said outer ring and any pair of adjacent tapered rollers; wherein said roller presser comprises a ring having a diameter smaller than said minimum diameter of said tapered raceway of said outer ring, and a plurality of arms extending from one side of said ring; wherein said respective arms are circumferentially spaced from each other and are inserted in every or every other one of said spaces so as to be substantially parallel to said tapered raceway of said outer ring, each of said arms having longitudinal edges in contact with the tapered rollers on both sides thereof; wherein each of said arms has a distal end remote from said ring; wherein an engaging portion is provided at the distal end of at least one of said arms and engages at least one of said tapered rollers; wherein the distal ends of at least an adjacent pair of said arms constitute free ends such that said adjacent pair of said arms are not joined to each other at said distal ends thereof.
