Abstract
To permit stacking of seals without possibility of the stacking of their synthetic rubber seal members to one another, permit, when assembling the seals to produce anti-friction bearings, storing the seals as a stack in a stocker of an automatic assembler and, unlike the case of using silicon or like prior art anti-sticking material, substantially eliminate generation of fine particles or the like adversely affecting precision apparatuses and deteriorating the reliability thereof. In an anti-friction bearing comprising an inner ring (1), an outer ring (2), and rolling elements (3) provided between the inner and outer rings, the side gap between the inner and outer rings is closed by seals (4), which each include a synthetic rubber seal member (6) and a surface active material (7) coated thereon.
