<p><P>PROBLEM TO BE SOLVED: To provide a roller bearing that produces an effect for creep prevention and bearing vibration reduction. <P>SOLUTION: The roller bearing has an outer ring 3, an inner ring 2, a plurality of rolling elements 4 provided between the outer ring and the inner ring, an annular o-ring 11 provided on an outer circumference of the outer ring, and a dent 12 is formed on the o-ring 11. The dent 12 holds oil and grease, so that oil can be supplied to between the outer ring and a housing due to bleeding of oil and grease from the dent. Further, as the dent 12 reduces elasticity of the o-ring 11, a damper effect is exerted, and thus bearing vibration can be reduced and creep can be prevented without depending on an attachment state. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
