摘要

The bearing (1) has two flanges (7.1,7.2) exhibiting inner bearing ring (2) and outer bearing ring (4). The outer bearing ring surrounds inner bearing ring under leaving an annular space (5) coaxially with rolling elements (3). A raceway (6) is provided in annular space (5) of the bearing rings. The seals (8.1,8.2) are used to seal the annular space to the environment. One of the seals is extended toward rotational axis (R) towards ends (19.1,19.2) to completely penetrate a hole (18). The hole is opened into a space (16) remained between the seal (8.2) and flange (7.2).
