FIELD: machine building.

SUBSTANCE: invention relates to the field of seals, and more specifically to the cassette sealing structure, which is mainly used for seals of bearings in the field of railway transport, and a tapered roller bearing, in which a cartridge sealing structure is used. Sealing structure (1) of box-like type is mainly ring-shaped and contains oil-reflecting ring (11) and sealing ring, wherein sealing ring comprises frame (12) and sealing section (13) attached to frame (12), oil-reflecting ring (11) is equipped with axial part, which extends along axial direction, oil-reflecting ring (11) is additionally equipped with first centrifugal structure, which is located closer to inner side along axis in comparison with axial part of oil-reflecting ring (11), first centrifugal structure is equipped with first bent section (11a1), which extends towards the axially inner side and, simultaneously, extends towards the radially outer side, sealing section (13) comprises the first sealing closing section (131), which is located on the radially outer side of the first bent section (11a1) and which is located at a distance from first bent section (11a1), and the first sealing closing section (131) at least partially extends towards the axially inner side in the axial direction to a position, which is located at same level with first bent section (11a1). Further, a tapered roller bearing comprising a box-type sealing structure (1) is provided. Sealing structure (1) of box-type type and conical roller bearing improve sealing action for oil medium.

EFFECT: disclosed are a cassette sealing structure and a tapered roller bearing.
