The invention relates to a plug assembly for use in a rolling bearing comprising a first ring (10), a second ring (12), and at least one row of rolling elements (14) arranged between the first and the second ring. The first ring (10) is provided with an opening (18) for inserting the rolling elements (14) into a space between raceways (10a, 12a) of the rings (10, 12) or for acquiring the rolling elements (14) from the space between the raceways (10a, 12a). The plug assembly comprises a plug (20) constructed to seal the opening (18) when the bearing is operating. The plug (18) forms a portion of the raceway (10a) and has an inner end face (20a) facing the rolling elements (14) and an outer end face (20b) facing the inner end face (20a). The plug assembly further comprises a protective cap (28) to protect the outer end face (20b) of the plug (18) from a corrosive environment of the bearing. |
