Abstract
A sealed rolling bearing includes an inner ring and an outer ring defining a bearing space therebetween. Axially inner and outer contact seals are provided on each side of the bearing space to seal the bearing space. The axially outer contact seals stop any splashed muddy water, thereby keeping the lips of the axially inner contact seals and their sliding contact surfaces free of muddy water. This prevents the lips of the axially inner contact seals and their sliding contact surfaces from becoming worn by muddy water. The axially inner contact seals thus maintain high sealability even if the bearing is used in environments where muddy water splashes.
