An assembly for sealing a rotating shaft and a bearing housing which has a stator, a rotor, and a unitizing element. The stator has at least two portions and an annular engagement flange extending in an axial direction having a groove on a radial side thereof. The rotor has at least two portions and an annular engagement flange extending in an axial direction having a groove on the radial side thereof. The annular unitizing element has at least two portions, a stator engaging member that engages the stator groove, a rotor engaging member that engages the rotor groove, and a rear member having a side edge that engages the stator. A radially outer surface of the unitizing element has two areas of differing diameter, one corresponding to the rotor engaging member and the other corresponding to the rear member.

Split bearing isolator and a method for assembling seal

A bearing isolator assembly for sealing a rotating shaft with a porous sealing element including a rotor configured to sealingly engage with a shaft, and a stator configured to sealingly engage with a housing of an assembly. The rotor and stator are configured to engage with each other to define a labyrinthine pathway and one or more cavities, in which may be disposed a unitizing element and a porous sealing element. The porous sealing element provides a barrier to particulate contaminants from entering the interior of the housing, and to prevent egress of lubricants from the interior of the housing. The unitizing element limits axial and/or radial movement of the rotor with respect to the stator, and helps prevent wear of the rotor and/or stator by helping prevent the rotor from contacting the stator during operation.

Bearing isolator with porous seal

An annular unitizing element has a rotor engaging member, a stator engaging member, and a rear member. The radially outer surface of the unitizing element has two areas of differing diameter, one corresponding to the rotor engaging member and the other corresponding to the rear member. The stator engaging member extends radially inward from the radially inner side of the annular unitizing element. A sealing assembly for sealing a rotating shaft and a bearing housing has a rotor having an annular engagement flange extending in an axial direction comprising a groove on a radial side thereof, a stator having an annular engagement flange extending in an axial direction comprising a groove on a radial side thereof, and an annular unitizing element having a stator engaging member, a rotor engaging member, and a rear member.

Unitizing element and method for assembling a seal

An annular unitizing element comprising a rotor engaging member, a stator engaging member, and a rear member. The radially outer surface of the unitizing element comprises two areas of differing diameter, one corresponding to the rotor engaging member and the other corresponding to the rear member. The stator engaging member extends radially inward from the radially inner side of the annular unitizing element. A sealing assembly for sealing a rotating shaft and a bearing housing comprising a rotor comprising, an annular engagement flange extending in an axial direction comprising a groove on a radial side thereof, a stator comprising, an annular engagement flange extending in an axial direction comprising a groove on a radial side thereof, and an annular unitizing element comprising, a stator engaging member, a rotor engaging member, and a rear member.
