摘要:
In one aspect, a seal case is provided for a roller bearing assembly having a central axis. The seal case includes an annular first end section including a rim configured to engage an outer ring, an intermediate section including a radial wall extending inwardly from the first end section and an axial wall extending axially away from the radial wall and the first end section, and an annular second end section extending radially inward from the axial wall of the intermediate section. The seal case further includes an insert of the first end section made of a first material. The first end section and the radial wall of the intermediate section include a second material joined to the insert. The first material of the insert may be selected to provide improved durability and/or to resist expansion and contraction of the first end section caused by changes in temperature.
