ABSTRACT:
A seal for roller bearings having inner and outer rings, especially for bearings in electrical machines, comprising at least two sealing disks spaced a certain distance apart on one or both sides of the rolling elements between the rings, one of said sealing disks being attached to one of the bearing rings and with its free end engaging in an annular groove in the other bearing ring, and where the gap between the disks is sealed by flock fibers, characterized in that the one sealing disk, on its free edge near the annular groove, has flock fibers projecting perpendicularly from its surfaces, which fibers are arranged to make slight frictional contact with the surfaces of the annular groove and with the opposite lateral surface of the other sealing disk said other sealing disk being slotted and nonrotatably mounted in the annular groove and having, on the lateral surface facing the sealing disk, a layer of flock fibers, the free ends of which are in contact with the sheet metal part of the sealing disk.
