ABSTRACT:
The invention permits stacking of seals without possibility of the sticking of their synthetic rubber seal members to one another. Moreover, when assembling the seals to produce anti-friction bearings, the invention permits 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 eliminates 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, a side gap between the inner and outer rings is closed by seals (4) of the invention, which each include a synthetic rubber seal member (6) and a surface active material (7) coated thereon.
