ABSTRACT:
A flexible seal and seal assembly is disclosed for use in rolling mills where roll necks are journalled for rotation in oil film bearings.
The flexible seal has a circular seal body adapted to be mounted in sealing engagement on a tapered section of the roll neck for rotation therewith, and a pair of circular flexible flanges integral with and extending radially outwardly from the seal body with at least one of the flexible flanges being provided at its outer edge with an angularly extending flexible annular lip.
The seal assembly includes the aforesaid flexible seal surrounded by a circular non-rotatable rigid seal end plate having a radially inwardly extending rigid flange separating oppositely extending rigid shoulders. The rigid flange is located between the flexible flanges of the seal, with its inner edge spaced radially from the seal body. The shoulders of the seal end plate have cylindrical shoulder surfaces which are parallel to the rotational axis of the roll neck and which are arranged to be sealingly engaged by the flexible annular lips of the seal.
