Conical roller bearing

Claim 1

In a conical roller bearing having an outer race and an inner race spaced radially and defining tapered bearing surfaces spaced further apart at the axially outer end portion of said bearing surfaces, a plurality of rollers held between said inner race and said outer race, a retainer holding said rollers, and a seal fitted between the axially outer end portions of said outer race and said inner race, said seal having a rigid portion fitted to the axially outer portion of said outer race and an elastomeric portion positioned adjacent said inner race, the improvement wherein said retainer includes an outer portion extending axially outwards from said rollers and said rigid portion includes means extending radially inwards from said outer race at a position adapted to engage the adjacent outer portion of said retainer as said retainer shifts axially outwards relative said outer race for preventing the axially outer end surfaces of said rollers from engaging any portions of said seal, said rigid portion including a circumferential member fixed to the inner radial surface of the outer end portion of said outer race, and said means includes an angled member having a circumferential portion fitted to the radially inner surface of said circumerfential member and a flange portion depending radially inwards of the axially inner portion of said circumferential portion.
