摘要: A chain guide includes roller element bearings adapted to guide, while rolling, a timing chain through which torque is transmitted. The chain guide further includes a guide base arranged along one side of the timing chain and having an opposed pair of side plates. Each side plate is formed with plural shaft engaging portions arranged so as to lie on a circular arc. The chain guide further includes roller shafts having their ends supported by the respective shaft engaging portions, and rotatably supporting the roller element bearings. An oil guide hole is formed in a wall surface of each shaft engaging portion facing the end surface of the roller shaft so as to extend through the side plate to its outer side surface.

摘要: 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.
