<P>PROBLEM TO BE SOLVED: To provide a bearing for a resin pulley capable of improving a bearing lifetime and acoustic characteristics by suppressing vibration and temperature rise of the bearing. <P>SOLUTION: The bearing 10 for the resin pulley is provided with an outer ring 11 including an outer ring raceway surface 11a on an inner circumference surface thereof, an inner ring 12 including an inner ring raceway surface 12a on an outer circumference surface thereof, and a plurality of rolling elements 1 3 arranged between the outer ring raceway surface 11a and the inner ring raceway surface 12a in such a manner that the same can freely roll. The resin pulley 16 is formed on an outer circumference surface of the outer ring 1 as one unit and circularity of the outer ring raceway surface 11a of the outer ring 11 is in a range of 0.3-0.5 μm. <P>COPYRIGHT: (C)2008,JPO&INPIT |
