ABSTRACT:
A bearing, having an inner ring, an outer ring, rolling members, inner seal members, outer seal members, a first grease having good heat resistance which is contained inward of the inner seal member, and a second grease having water-resistance and corrosion-prevention which is contained between the inner seal member and the outer seal member. The second grease prevents rusting in the outer and inner rings even if water enters the inner side of the outer seal member. The first grease assures satisfactory lubrication of the rolling members, the outer and inner rings under high speed and high temperature conditions.
