In a rolling mill, for use in combination with a roll neck 9 surrounded by a bearing sleeve 7 fixed thereto, the bearing sleeve 7 being journalled for rotation in a non- rotatable bushing 1a contained in a bearing chock 1, with the roll neck 9 having a tapered section 9a leading from the neck portion surrounded by the sleeve 7 to an end face on the roll barrel 8, and with lubricant being provided between the bearing sleeve 7 and bushing 1a, a seal assembly is provided surrounding the tapered roll neck section 9a and fixed relative to the bearing chock 1. A circular flexible seal 10 is mounted on the tapered roll neck section 9a for rotation therewith. The flexible seal has a flange 11 extending outwardly therefrom into sealing contact with an adjacent surface 6 of a seal end plate 3. An outer seal ring 3a is fixed relative to the seal end plate 3. The outer seal ring 3a has a cylindrical inner surface cooperating with the seal end plate to define a circular cavity 20 opening towards the end face of said roll barrel 8. A seal inner ring 21 has an inner portion 21c abutting the flexible seal, an outer peripheral portion 21a protruding into the aforesaid cavity, and lips 25, 24 sealingly contacting the roll end face and the inner cylindrical surface on the outer seal ring 3a. <IMAGE> |
