This is a two-row bearing assembly with two inner races and a one piece outer race. The outer race has a heavy wall section, which is self-supporting, allowing the bearings themselves to be used directly, for example, as steady-rest rollers, in sheet and strip levellers. The outer race is extended at both ends and counterbored to accept stamped closure and the bearings can be supplied with these ready fitted as unit assembly(but not pre-lubricated) Rubbing seals also available for certain sizes.
